Application
EMGA-600W Oxygen/Nitrogen/ Hydrogen Combined Analyzer
Overview
The HORIBA EMGA-600 is a combined model between ON and H analyzers and determines the oxygen, nitrogen and hydrogen contained in ferrous and non-ferrous metals, semiconductors, electronic materials and so on using the inert gas fusion method.
The oxygen is measured as carbon monoxide by a non-dispersive infrared detector and the nitrogen and hydrogen are measured by a thermal conductivity detector. The detectors for O/N/H are connected to the same single furnace through a gas selection unit.
