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.
Your TOC analysis has never been easier with LECO’s solutions
Carbon is an essential building block of life on our planet. The amount of Carbon present is an important factor in soils and agriculture samples.
The determination of TOC in solids has recently become ever more important, not just for evaluating wastes but TOC content measurements are also an important aspect of assessing soils.
The Carbon present in soil organic matter is referred to as organic Carbon. Soil organic Carbon is a vital component of productive agriculture. In addition sequestration of Carbon in agricultural soils has been recognised as a tool to mitigate climate change.
LECO provides innovative and timesaving analytical instrumentation for the analysis of organic Carbon content.
Specific Advantages Including
- Market leading analytical performance
- Simplified sample preparation
- Robust & reliable instrumentation
- Unsurpassed instrument flexibility
- Adhering to all the current standards, such as ISO 10694, BS EN 17505 and EN 15936
Instrument Portfolio for TOC Analysis
CS744 // Carbon analysis by combustion
Redefine the way you determine carbon in soils and plant tissues with our 744 series. Using extensive customer feedback and innovative engineering, the 744 takes advantage of our immersive CORNERSTONE® brand software platform and a number of features, ...
... such as an improved IR cell design and available automation, come together to increase usability, lab productivity, and lower your cost-per-analysis.
RC612 // Multi-Phase Carbon And Water Determination
Get fast, reliable carbon and water determination with our RC612. The RC612 is a resistance furnace multiphase carbon and moisture determinator which quantifies the carbon and moisture present in soils and plant tissues and illustrates the source of several types of carbon.
The RC612 features a state-of-the-art furnace control system, which allows the temperature of the furnace to be stepped and ramped from near ambient to 1,100 °C, in either oxidative or reductive carrier gas. The RC612 utilizes an afterburner furnace that ensures complete combustion of volatile species released at lower primary furnace temperatures.
SC832 // Sulfur And Carbon Analysis
LECO’s 832 series of Elemental Determinators are specifically designed to perform carbon and sulfur analysis of soil, plant tissue and other organic and some inorganic materials. The 832 series is a valuable resource for any laboratory needing fast and accurate analysis.

Methods of TOC analysis include
1. Acid Digestion Method
The most common method for determining TOC is the acid digestion method. By acid treating a sample, usually with hydrochloric acid, which is strong enough to react with inorganic carbonates but does not react much with organic Carbon, the inorganic carbonate species within the sample will effervesce as Carbon dioxide. The acid-treated sample and a non-acid-treated sample can both be analyzed using either the LECO C744 series or LECO C832 series for Carbon content. The untreated sample would indicate the total carbon content, while the acid-treated sample’s Carbon content would be the remaining organic Carbon content. The difference between the two samples would be the total inorganic Carbon (TIC) content.
2. Temperature Dependent Method
Another Carbon determination method is temperature dependent. With the temperature dependent method, samples do not need to be pretreated. Organic Carbon combusts to CO2 between 150 °C and 450 °C, while inorganic species combust below 1,000 °C. The RC612 resistance furnace multiphase Carbon and moisture determinator performs this analysis by using a two-step temperature ramping at 450 °C and 1,000 °C without any acid pretreatment of the samples. The CO2 gases are swept through to an NDIR at 450 °C and again at 1,000 °C to determine the TOC and TIC in the sample.

Determinazione del carbonio organico totale (TOC) nel suolo mediante trattamento acido e differenziazione della temperatura
Presented by Jeffery Gast
The presentation will outline TOC determination in soil using two different approaches. First, we will explore the use of acid treatment of the soil to remove carbonates followed by analysis using conventional combustion techniques. Next, we will explore using a ramped furnace temperature approach to differentiate organic and inorganic carbon species. TOC results from both approaches will be presented.

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.

Total sulfur value is an important characterisation measurement for coal, coke, fuel materials, and a wide variety of other organic materials. It is considered to be part of the ultimate analysis parameters (determination of carbon, hydrogen, nitrogen, sulfur, and ash with oxygen calculation by difference). The total sulfur value is a primary parameter used for assessing the quality of a fuel, calculating coal and coke preparation and cleaning processes, and the emissions potential of the fuel. The SC832 Series will bring productivity, precision, and progress to your lab when determining the sulfur and carbon content of your samples.

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.
