EMGA-921 typeHydrogen analyzerIt is the flagship model and user-friendly instrument for hydrogen analysis.
This is a high-precision, high repeatability hydrogen element analyzer suitable for material research and quality control in fields such as steel, new materials, catalysts, etc. This is a brand new product that has been optimized to meet the requirements of users.
The detection of hydrogen element is achieved by measuring hydrogen gas using thermal conductivity detection method.
Principle and Gas Flow Path Diagram
Place the sample in a graphite crucible, keeping the crucible between the upper and lower electrodes of the pulse furnace. A high current passes through the crucible to generate high temperature.
The hydrogen in the sample is released as hydrogen gas (H2), and its concentration is measured by a thermal conductivity detector (TCD).

high performance
Wide hydrogen detection range: 0-0.02%
Optimize the design of TCD detector for hydrogen detection.
●precision
SD ≤ 0.04 μ g/g or RSD ≤ 0.5%, whichever is met (reference gas)
●standard method
EMGA-921 complies with the requirements of various metal (titanium, zirconium, tantalum, etc.) analysis standard methods in JIS Z2614, JIS H1619, JIS H1664, JIS H0696, ASTM E1447.
Analysis example of JSS sample containing low concentration of hydrogen.

Humanized software
Detection interface
Humanized software makes operation exceptionally easy
The extracted gas signal is displayed in real-time in digital form, and is also displayed as a curve along with the temperature level. The release curve graph will be automatically saved.
In the measurement window, the sample weight can be automatically registered. The results are saved in a data table for easy management.

HORIBA's original maintenance navigator
Notify users when consumables need to be replaced to maintain the best condition of the equipment.
The method and steps for replacing parts described in the maintenance navigator are simple and easy to understand, and operators can carry out maintenance work without experience and technical reserves.
