EMA 502 Elemental Analyzer working principle

EMA 502 Elemental Analyzer working principleEMA 502 - CHNS Flowpath

The CHNS analysis starts with the combustion of the sample inside the VELP combustion furnace at a temperature higher than 1000°C to obtain elemental compounds.

VELP Vcopper™, a formulation of highly active copper powder, is placed in the lower part of the reactor to help the reduction of NOX into N2.

The flow then reaches the gas chromatographic column oven, which ensures homogenous and modular temperature leading to a complete separation of all the elements for the final detection by TCD.

When analyzing Oxygen, the sample undergoes pyrolysis inside the furnace and then passes through a chemical trap where all impurities are absorbed, before reaching the gas chromatographic column and the TCD for detection.
