Consistent performance, proven accuracy and tested reliability

Results are automatically calculated by the EMASoftTM?software receiving real-time data from EMA 502 Elemental Analyzer.
Get a comprehensive understanding of the analysis output before even checking on the results thanks to the?gas chromatographic column?and?TCD, which?enable a real-time view of the analytical process and pathway with premium performance for the whole instrument life span.
EMA 502 Elemental Analyzer working principle

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

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.
