He or Argas according to method
Direct response
The EMGA HORIBA line is especially focused on O, N and H in metals, steels, alloys, copper, titanium and metallic powders. The sample is fused in graphite crucible under inert gas, and the extracted gases are measured by NDIR and/or TCD according to the model.
Highlights
Residual gases as a material indicator
O, N and H influence properties, processability and reliability. The EMGA family offers configurations for O/N, O/N/H and hydrogen ultratrace.
02
Selective detection
NDIR and TCD applied to gases formed and conditioned in the analytical flow.
03
Simplified maintenance
Project oriented to exchange electrodes, dust filter and preventive routines.
04
Scalable automation
Options for crucibles, samples, cleaning and integration with host system.
Measurement principle
How Inert Gas Fusion Works
Extraction
The sample is fused in graphite crucible to release the gases formed.
Inert-gas flow
Helium or argon transports the extracted gases according to the configuration.
Conditioning
Reagents and columns remove interfering or convert species for each element.
NDIR and TCD
CO/CO2, N2, H2O or H2 are measured according to the model and method.
Equipment

Frequently Asked Questions
HORIBA EMGA — technical information
What is the EMGA HORIBA line?
It is a family of oxygen, nitrogen and hydrogen analyzers in metals and solids. The sample is fused under inert gas and the extracted gases are measured by NDIR and/or TCD.
What is the difference between EMGA-Pro and EMGA-Expert?
The Pro meets selected tracks and is positioned as input solution. Expert expands range and ultratrace performance and offers greater flexibility of options and automation.
Can EMGA operate with argon?
Yes. For nitrogen analysis, the specified performance can change with air; the gas must be defined for the method.
What is the difference between EMGA-30E and EMGA-21E?
The 30E measures O, N and H. The 21E is dedicated to H ultratrace, measures H2 by TCD after column separation and has its own range and cycle.
