EMA 502 Elemental Analyzer working principle

EMA 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 NO_X 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.

Unmatched ease-of-use and data security with EMASoft™ software

The EMASoft™ software is the powerful VELP solution that controls and operates the EMA 502 elemental analyzer.

EMASoft™ comes with a user-friendly interface that displays all the relevant information at a glance: results, database, and instrument working conditions.

It is possible to choose from a library of pre-installed methods and create customized ones. An easy calibration curve creation for all the elements allows for testing of any sample matrix with no memory effect.
