EMGA-921 Hydrogen analyzer: It's a "New flagship model” for H analyzer and user friendly product.
This is an hydrogen elemental analyzer with high accuracy and repeatability suiting to cutting-edge technology’s R&D as well as quality control in the market of steel, new materials, catalyst and so on. This is a new generation model optimized to fit to user’s requests. The hydrogen is measured as H2 by a thermal conductivity detector.
Features
- Principle and Gas flow diagram
The sample is placed in a graphite crucible and the crucible is maintained between the upper and the lower electrode of the impulse furnace. A high current power passes through the crucible to create a high temperature. The Hydrogen in the sample is extracted as Hydrogen gas (H2) and its concentration is determined by a thermal conductivity detector (TCD).
- Super High Performance
Wide measurement range Hydrogen: Up to 0.02%
Optimized TCD design for hydrogen.
Precision
Hydrogen: SD?0.04µg/g or RSD?0.5% whichever is larger (Reference gas)
Standard method
EMGA-921 fulfills requirements of the standard methods for analysis of various metals(titanium, zirconium, tantalum etc.) JIS Z2614, JIS H1619, JIS H1664, JIS H0696 ASTM E1447
- User-friendly Software
Simple software allows easy handling. Extracted gas signals are displayed in real time numerically and also as curves together with temperature level. Graphs are saved automatically. In the measurement window, sample weight can be registered automatically. Results are saved in a data table for easy management.
- HORIBA originality-Maintenance navigator
Maintenance counter informs users at the timing of consumables replacement to keep high accuracy means.
And as navigator describes the easy to understand procedure for the replacing parts, operator can do maintenance works with absolutely no experience and technical knowledge.
