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

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.

Total Organic Carbon (TOC) Determination in Soil Using Acid Treatment and Temperature Differentiation
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.

The Dumas method has several advantages over the Kjeldahl method: it is much faster, with much lower operating costs, no real safety issues, and no toxic waste produced. However, there is a debate over which of the two main approaches to the Dumas method is better: a vertical or a horizontal combustion furnace. Determined to settle the question on which method is more precise and offers the most advantages, LECO chemists analyzed many sample types in both an FP828 and an FP928.
For more information and a detailed breakdown of the results and a look at more of the samples used in this experiment, read Michael Jakob's article in the September 2021 issue of 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.

Well-balanced crops require well-balanced soil. While carbon may be the most essential element for organic life, the right ratio of nitrogen and sulfur in the soil along with the carbon can really influence the speed and strength of plant development and growth. With a macro combustion carbon, nitrogen, and sulfur determinator such as LECO's CNS928, those ratios can be discovered easily through fast and precise analysis.
There are countless fertilizers that can be applied to change the ratio of elements in soil, but without knowing the baseline for your soil, you have no practical way of knowing what it needs. LECO's CNS928 can take some of the uncertainty out of soil management.
While helium remains the inert gas of choice for elemental analysis, supply is limited, driving cost up. The CNS928 is designed to support the use of either helium or argon as a carrier gas. The thermal conductivity difference between argon and nitrogen is not as great as the thermal conductivity difference between helium and nitrogen, so the detector is inherently less sensitive when using argon for nitrogen determination, but the CNS928 does offer the option of using a larger 10 cm3 aliquot loop. The 10 cm3 aliquot loop helps to overcome the lower sensitivity of argon carrier gas by optimizing the system for the lowest nitrogen range and provides the best precision.
To see how the CNS928 handles carbon, nitrogen, and sulfur determination with various combinations of carrier gases and aliquot loop sizes, read the app note.
