OF

⮱Rapidly determine the carbon, hydrogen, nitrogen, sulfur, or oxygen in inorganic and other types of materials. Our proven elemental analyzers handle a wide variety of sample types including solids, liquids, volatile and viscous samples. Examples of how our elemental analysis technology is applied today include:

  • Pharmaceutical / Chemical: confirmatory analysis, purity
  • Energy: C/H Ratio of fuel, BTU analysis of coal, impurities analysis
  • Polymers: blend analysis, nitrogen level
  • Environmental: C/N ratio in soil, sediment and plant material, organic particulate collected on filters, nitrogen content in fertilizer
  • Food / Animal Feed: protein content, product labeling
  • Explosives: nitrogen content

    Organic Elemental Analysis of Soils -- Understanding the Carbon-Nitrogen Ratio

    Understanding the health of the soil in which crops grow is fundamental in ensuring healthy yields. Two elements that are essential to this are Carbon and Nitrogen, especially in their proportion to each other. This relationship is called the CarbonNitrogen or CN ratio. This ratio is relatively simple to understand. If soil is made up of 30% Carbon and 2% Nitrogen then the CN ratio is 15 to 1. The EA2400 CHNS/O Analyzer is shown to be a powerful tool for the analysis of soil samples of varying organic contents. It is shown that along with CN ratios, TOC and TIC measurements can also be performed to a high level of accuracy. It has also been shown that the EA2410 Nitrogen analyzer can also perform Nitrogen measurements on soil to high levels of accuracy.
