Dr. Belen Morales, Head of Analytical Services from the Sheffield Assay Office in an interview with LECO
"[...] I have experience with LECO for years. To summarise is very, very simple. The reason why I bought the last machine from LECO, the Oxygen, Nitrogen, Hydrogen analyser was because in the market it’s the best in terms of practicality. The fact that I can do the multi element analysis at the same time for Oxygen, Nitrogen and Hydrogen is a really benefit for me. You do not have this in most other competitors. Also, the aftersales service is something that is perfectly working for LECO. We have service contracts with LECO on all our instruments and are very happy with the aftersales support we get. [...]"

Quando la miniera di ferro di Kaunis aprì in Svezia, fu la più recente in una delle più grandi industrie svedesi. La miniera stipulò un contratto con il Degerfors Laboratory (D-LAB) per l'analisi del ferro. Prima che l'analisi potesse essere eseguita sui campioni, tuttavia, era necessario essiccare il minerale e misurare i livelli di umidità.
D-LAB ebbe un problema: i loro attuali metodi di determinazione dell'umidità utilizzavano una bilancia manuale che poteva gestire solo un campione alla volta, richiedendo l'attenzione di un tecnico ogni cinque minuti. Anche il metodo ISO 3087:2020 utilizzato rappresentava un problema, poiché il completamento di una singola esecuzione poteva richiedere più di 5 ore. Il laboratorio si rivolse a LECO per una soluzione.
Il metodo Dumas presenta diversi vantaggi rispetto al metodo Kjeldahl: è molto più veloce, con costi operativi inferiori, nessun reale problema di sicurezza e nessun rifiuto tossico prodotto. Tuttavia, c'è un dibattito su quale dei due approcci principali al metodo Dumas sia migliore: un forno a combustione verticale od orizzontale. Determinati a risolvere la questione su quale metodo sia più preciso e offra i maggiori vantaggi, i chimici LECO hanno analizzato molti tipi di campioni sia in FP828 che in FP928.
Per ulteriori informazioni e una ripartizione dettagliata dei risultati e uno sguardo a più campioni utilizzati in questo esperimento, leggi l'articolo di Michael Jakob nel numero di settembre 2021 di eFOOD-Lab International.

"Moisture analysis is typically a classical gravimetric technique when analysing both food and animal feeds. As such there is a considerable amount of 'hands on' analyst time to ensure accuracy. Freeing up analyst time allowing focus on other testing was the drive and automation of tests such as moisture was key to achieving.
The laboratory was aware of systems on the market which it could use to automate the moisture analysis but dealing with companies with a trusted track record, allowing an easier route to commission any such testing, was very important under our accreditation. We have used LECO instrumentation for nitrogen testing for over 20 years and therefore we felt that initial discussion with the company was justified. The instrumentation was then purchased on time and on budget. Communication with the representatives and technical specialists during the purchase was excellent.
We have had a long association with using LECO instrumentation particularly in the field of nitrogen/protein testing and they are viewed as a leader in this field. Reliability and accuracy of equipment is very important in the enforcement field and our experience is that LECO instrumentation delivers on both. The instrumentation (TGM) purchased was also at an affordable cost which ticked another box for us.
Time savings have been made as the analyst only has to weight the samples and set the instrumentation going and the rest is automated. Checking that the weighings are 'true' and to constant weight is the next intervention but this is clear from the analytical printout and takes little time and effort. So the time process of moisture determinations has now been optimised and we are achieving good external proficiency test results enhancing confidence in the figures reported to customers.
The equipment is robust, accurate and well priced compared to others on the market. LECO are a well established company with a long track record to producing high quality and reliable instrumentation. We are over cautious in terms of our suppliers of instrumentation in terms of the legal implications of the samples we are testing and the constraints of the ISO 17025 accreditation we work to. But LECO instrumentation we have used has never failed to deliver. Excellent after sales care is another bonus and engineers and reps are easily accessible."

"At Livelab we have always used LECO instruments for their accuracy and reliability, but also for their reputation. If a customer knows that we have tested their samples on the LECO, then they have an increased level of confidence in the results that is important to us. I have a bit of a reputation amongst our employees for having a soft spot for LECO instruments, precisely because of their reliability and also their ease to maintain. For us, they are the number one name in CNS determination, and to that end we have two SC144 instruments, two FP528 instruments and one FP628 Nitrogen determinators. Easy to use, rarely goes wrong, easy to fix if it does, and the top name in the industry – why use anyone else?"
The past year with the rise of Covid-19 around the Earth has been a challenge to all of us. See how our European subsidiaries dealt with the pandemic around Europe and how our customer support and other services adapted to these new situations in the different countries.

The start of the years begins with the usual enthusiasm, targets set, goals to achieve and strategy to achieve them. I remember being in Dusseldorf for a managers meeting on March the 3rd. Life was still normal, and the word ’lockdown’ was only ever heard on a Friday when my children were watching Wrestling. We were able to travel, visit restaurants and have a beer without the constraints of the facemasks, social distancing and track and trace apps. Life was normal. Within a month the world changed – lockdowns, stay-at-home, work from home, stay safe.
As the LECO customers adapted to this new way of life due to COVID, so did we. Our sales force worked from home and like never before used this relatively unheard-of platform called Microsoft TEAMS to interact with customers.
“I hear the chimes of ‘TEAMS’
calling me in my sleep now.”
Our service team continued to work throughout the pandemic with the new additions to their LECO uniform. LECO face masks and gloves. And of course, let’s not forget the bottles of hand sanitiser. As well as remote selling was used, remote service support came to the forefront. Both sales and service teams adapted to continue the high level of support that has become a custom with LECO.
LECO UK has been able to adapt and continued to support our customers while keeping ourselves and customers safe. Let hope moving into 2021 we can get back to some sort of previous normality. The vaccines are coming and there is a glimmer of light at the end of the tunnel but for the moment we continue with the slogan of Hands – Face – Space.

It has for sure been a challenge even though Sweden have had less restrictions. When crossing borders to Norway, Denmark and Finland our service technicians have sometimes had to take Covid-19 tests before. We have been fortunate, no one in our team have been infected as we know of. We haven’t even been to Iceland since the start of the pandemic. Our service technicians try to go by their own cars to customers, which have meant drives up to 14 hours single way.
On the sales side it has of course been a challenge in other ways. But with ‘Teams’, online demos and Virtual Trade show our sales team have connected with our customers in the best way possible. We only attended one real trade show since the start of the pandemic – LabDays in Copenhagen – but the attendance was of course quite thin…
Lennart Schwartz, Ph.D, Sales Director Nordic Region, LECO Nordic AB
Since 14th of March of 2020, and the declaration of State of alarm in Spain, Leco Instrumentos started to work in a new different way, adapting to the new scenario of pandemic. All the employees completed a training course regarding the new risk at work and the personal protective equipment for COVID-19:
- We all learnt about the use of face masks and the way to wash our hands
- Some employees customised their masks… thanks to their mother’s support!
- Remote working was the only option in most of cases.
- Virtual meetings have come to stay.
- The service team has been active since the first day, working in safe conditions.
So far, everything was normal… But LECO Spain had to face a new challenge – to move to a new office. It was a hard task cleaning the old facilities and open boxes – a lot of boxes. And in times of COVID we had to consider to organise small groups at the office working together. Minimising risks was a priority despite of the fact that we needed to be operative in the new facility in a short time. The collaboration of the Tres Cantos-based employees was essential.
But the result made the effort worthwhile! And the Spanish LECO team is ready for 2021!
Leticia García, Commercial Director, Spain & Portugal
From the perspective of the German Service Centre, a Corona routine has emerged throughout the past months. Customer demands increased - ever so often our service engineers are only allowed to enter labs after presenting a negative Corona test result. Of course, this requires special logistics in scheduling. In addition, there are different Corona rules the federal states of Germany and abroad, which makes planning much more difficult. But our colleagues adapt, as the pictures show, and as our colleague Manuel Lindemann describes below.
"When the pandemic really took off from March / April 2020, I first noticed a lot of uncertainty among both myself and the customers. There were many questions: What is Corona? What happens if I fall ill? How will this affect my work? Will the customers still let me enter their lab? How will LECO react? Now, almost a year later, there are still some questions left to be answered, but as humans we adapt and get used to the new circumstances – positive and negative.
in the beginning of the pandemic, I remember waiting for hours in 100m-long queues between lorry drivers and other visitors at a company and having to wait for the gatekeeper to let me pass. And there were customers who had their "special" views. From "Corona doesn't exist” to “You don't need the mask here" and "We have an internal lockdown, you can't get in" – it was all there.
After one year many questions remain unanswered, but some questions have already become obsolete. What remained as well, unfortunately, are the waiting times at customers‘ sites. Simply walking in and working on a unit is no longer possible. "Where are you from? Have you had contact with infected people? What does your Corona Warn app say? Do you have any symptoms?” ...And so on. What I've also noticed is that social interaction often gets left behind these days unfortunately – be it a casual conversation or just a gesture that disappears behind the mask. But, hopefully that is to come back soon.
But LECO protect their employees very well and always has an open ear for questions – a solution will be found together. All in all, I think we have organised ourselves very well and will probably make it through the rest of the pandemic."
Manuel Lindemann & Thomas Post, LECO Instrumente GmbH Deutschland
After a beginning of year full of prospects and projects, the arrival of Covid-19 took us by surprise. Italy was the first European nation to be massively attacked by the virus, the first cases recorded were in the north of the country, particularly in Lombardy, the region where the headquarters of the LECO branch in Italy are located.
To counter the spread of the virus, the entire country was placed in the "red zone" and operations were greatly reduced to adapt to the new situation.
- The symposium of world interest on the GC×GC in Riva del Garda, as well as other local events, albeit no less important, have been cancelled
- We did our meetings online
- The office staff worked in smart working
- The technical staff continued to follow their customers both remotely via the telephone and with remote interventions, and in person with the help of masks, gloves, overalls and protective goggles.
The pandemic has led us to cover our faces with masks, but it has not managed to extinguish our enthusiasm and we hope that 2021, together with the vaccine, gives us the opportunity to resume showing our smiles.
Rita M. Monfredini, LECO Italy S.R.L.
We’re dealing with the pandemic problem in a similar way, like the rest of the world:
- Using, masks and gloves
- Struggling with scheduling sales visits
- Mostly using ‘Teams’ and mobile phones to contact with each other and with customers…

Incorporando l’hardware all’avanguardia e una piattaforma software touch-screen integrata con tempi di analisi rapidi, il CHN828 opera a basso costo per analisi e consente agli utenti di gestire facilmente le applicazioni campione più esigenti.
Hai letto il nostro recente articolo su Food Navigator? È necessario misurare il contenuto di azoto negli alimenti quando si determina il contenuto proteico totale. La misurazione dell'azoto può essere eseguita utilizzando un metodo di chimica umida classico, ma tende ad essere un processo lento e noioso. Il metodo Dumas basato sulla combustione ha guadagnato popolarità negli ultimi anni, poiché aumenta significativamente la produttività del laboratorio. Tuttavia, quando il campione ha un basso contenuto di azoto, può essere difficile da analizzare. Esempi di questi campioni difficili da analizzare includono l’amido di mais secco, i sacchetti filtro NDIN, le bevande nutrizionali e la birra. Come si può ottimizzare il metodo di combustione per gestire questi campioni con azoto a bassi livelli?
Analisi carbonio/idrogeno/azoto/zolfo

Soil is the material where corn grows. This sounds to be a simple sentence, but keep in mind, that a big part our food is directly or indirectly coming from plants that are sown, grown and harvested in agricultural soil. For modern agriculture especially when including environmental concerns, the chemical analysis delivers very important parameters for a complete characterisation of soil. LECO is the specialist for CNS and moisture/ash analysis in soil, as well as for Carbon species analysis like TOC/TIC or according to EN 17505 TOC400, ROC, ROC900 and TIC 900.

AMG Superalloys UK Ltd
"AMG Analytical has been working on LECO machines for over 25 years for the determination of O, N, C and S.
We embarked on a project working with LECO to bring Hydrogen testing in-house. The outcome of the project was excellent!
We have now purchased a LECO ONH836 machine and will offer the testing of Hydrogen to its external customers.
In our experience the level of commitment, technical expertise and support provided by LECO is unique within the industry.
We have no hesitation in recommending LECO to any company wishing to improve the efficiency of their operations."
D-Lab
"For our business as an accredited contract laboratory we need very flexible instruments that remain stable in the long run. Flexibility for the ever-changing levels of alloying elements and also for the lack of reference materials. We therefore need a versatile instrument for analysis and research, i.e. possible to separate, and for serving our customer with extended element range. We need top of the range instruments. D-LAB has for a long time used LECO Instruments for analysis of C S N O H.
We are very happy about the ranges that the instrument can handle!"
Calcinor S.A.
"In the past, my company, CALCINOR S.A. used to carry out quality control tasks using muffle furnaces to determine Loss by Calcination.
When we acquired the LECO equipment to automate our process, we saw a significant improvement.
Our work with these instruments is very satisfactory and I emphasize the robustness of our LECO instruments because they are prepared for continuous work backed by LECO technical service. We continue to trust the LECO brand, acquiring their instruments when necessary."
AINIA
"LECO is undoubtedly a great brand synonymous with quality and professionalism that offers me Security and confidence.
Our AINIA chemical analysis laboratory has been using LECO equipment for more than 14 years!!, specifically the TRUSPEC N and a TGA701 thermogravimetric analyzer. We use these to routinely analyze solid foods such as pastries, sausages, pre-cooked meals, etc. and we are accredited for these tests by ENAC from time we began using these instruments. We do over 10,000 analyses per year!
LECO enabled us with the latest technology to carry out tests quickly, economically with higher PRECISION compared to traditional methods such as Kjeldahl for Total N or the muffles for humidity & ashes that are slower and more expensive. In all these years LECO has never failed us when we needed their Technical Service or help with a new application."
NSPLAV
"With LECO CS844 and ONH836 instruments, we can easily test our degassed chrome products and restrict gas-forming impurities to a very low level (~0.0005% ).
Reliability of the equipment and the speed of analysis is very important to me because it directly affects shipment of our finished products.
A big portion of our products are exported and for as long as we have used LECO instruments, we haven’t received any complaints for our analyses. The work of LECO Russia is noteworthy. They’ve been highly professional with us from providing recommendations for preparation of the room to methods for analysis of our samples. Warranty services are at the highest level and consumables are always available at their nearest warehouse.
We are highly satisfied and readily recommend LECO to other users."

“La mia azienda utilizza strumenti LECO per l’analisi CSNH dal 1973. Thousands and thousands of analyses, through day and night, in a steel shop laboratory… That’s hard work… both for the operator and the analytical equipment.
Dal 1973 la precisione e l’accuratezza continuano a migliorare!
Semplicemente una strumentazione robusta e affidabile! Semplicemente… LECO!”
Elektrowerk Weisweiler GmbH
"Even with an increase in the number of analysis per day, turn around times – over the years – could be maintained or even reduced. This was achieved without decreasing of the measurement accuracy and repair-related or maintenance-related shutdowns.
In Germany we have a saying that perfectly fits for LECO: The first car sells the sales, the second one the service. By the way, at LECO you get everything out of one hand. The quality of the consumables is the same as for the analyzers themselves.
"Never change a running system". The statement is true, but to have a ‘running system’ over the years requires a lot of efforts. LECO not only stands for the sale of equipment but is also always helpful in the continued operation of old equipment.
Simply speaking, the LECO analyzers are "workhorses" with a very long service life. The devices require only a relatively low own maintenance and the consumption of consumables are within normal limits."
Wallonian Agronomy Research Center
“Il Trumac CN è davvero molto valido rispetto a Elementar e Thermo Flash. Ecco i risultati di uno studio che ho condotto nel 2015. LECO TRUMAC è più preciso rispetto ad altri strumenti. One method fits all solid and semi-solid matrix, while with other instruments, the methods need to be customized for each sample matrix!"
Coal Services A.S.
"Our main instruments for 'fuel analysis' are LECO calorimeters AC500 & AC600, LECO TruSpec CHNS together with LECO CHNS628 and Thermogravimetric analyzers LECO TGA601 & TGA701. It could take us as little as 2 minutes per analysis and with the TGA we can simply load samples and continue working on other tasks! LECO understands the importance of our work and provides highly reliable services to keep these instruments in order. Thanks to remote consultation with LECO Service department they are never too far from us when we need help. Simply a great technology partner to have!"
Le colture ben bilanciate richiedono un terreno ben bilanciato. Sebbene il carbonio possa essere l’elemento più essenziale per la vita organica, il giusto rapporto tra azoto e zolfo nel suolo insieme al carbonio può influenzare davvero la velocità e la forza dello sviluppo e della crescita delle piante. Con un determinatore di carbonio, azoto e zolfo a combustione per campioni macro come il CNS928 di LECO, questi rapporti possono essere rilevati facilmente attraverso un’analisi rapida e precisa.
Esistono innumerevoli fertilizzanti che possono essere applicati per modificare il rapporto tra gli elementi del suolo; tuttavia senza conoscere la linea di base del suolo, non esiste un modo pratico per sapere di cosa esso abbia bisogno. Il CNS928 di LECO può eliminare alcune delle incertezze legate alla gestione del suolo.
Sebbene l’elio rimanga il gas inerte preferito per l’analisi elementale, l’offerta è limitata, aumentandone i costi. Il CNS928 è progettato per supportare l’uso di elio o argon come gas di trasporto. La differenza di conducibilità termica tra argon e azoto non è grande quanto la differenza di conducibilità termica tra elio e azoto, quindi il rilevatore è intrinsecamente meno sensibile quando si utilizza argon per la determinazione dell’azoto, ma il CNS928 offre la possibilità di utilizzare un loop di aliquota maggiore di 10 cm3. Il loop di aliquota di 10 cm3 permette di superare la minore sensibilità del gas di trasporto dell’argon, ottimizzando il sistema per la gamma di azoto più bassa e offrendo la massima precisione.
Per scoprire come il CNS928 gestisce la determinazione del carbonio, dell’azoto e dello zolfo con varie combinazioni di gas di trasporto e dimensioni del loop di aliquota, leggi la nota applicativa.
