The LECO CHN628 Series Elemental Analyser is used to determine nitrogen, carbon/nitrogen, and carbon/hydrogen/nitrogen in organic matrices. The instrument utilizes a combustion technique and provides a result within 4.5 minutes for all the elements being determined. The instrument features custom Windows -based software operated through an external PC to control the system operation and data management. In addition to the above, the machine also offers a Sulphur add-on module which provides sulphur analysis for any element combination. The 628 S module is specifically designed to determine the sulphur content in a wide variety of organic materials such as coal, coke, and fuel oils, as well as some inorganic materials such as soil, cement, and limestone. The series allows you to achieve rapid and precise results in diverse organic matrices from food to fuels. For optimum versatility, this instrument is available in flexible configurations nitrogen/protein, carbon/nitrogen, and carbon/hydrogen/nitrogen. The add-on module provides sulphur analysis for any element combination of the CHN628 Series-FP (N), CN, or CHN.
