EMGA-921 Hydrogen Analyzer

Description

The EMGA-921 Hydrogen Analyzer is a high-precision analytical instrument specifically designed for accurate and reliable hydrogen measurement in a variety of inorganic materials. As HORIBA’s flagship model for hydrogen analysis, the EMGA-921 delivers exceptional accuracy and repeatability, making it indispensable for advanced research and development, quality control, and production environments. It is particularly suitable for industries such as steel, new materials, catalysts, ceramics, semiconductors, and energy materials.

Advanced Detection with TCD Technology

The EMGA-921 uses a Thermal Conductivity Detector (TCD) to measure hydrogen as H₂ gas, ensuring highly accurate and dependable results. The analyzer achieves precision levels of SD ≤ 0.04 μg/g or RSD ≤ 0.5%, whichever is larger, enabling high-sensitivity measurements across a wide concentration range. This makes it ideal for both low-concentration and high-concentration hydrogen analysis in various metals and non-metals.

Applications:

The EMGA-921 is ideal for:

• Energy Materials (lithium-ion batteries, fuel cells, electrolyzers)
• Semiconductors (silicon, poly-silicon, GaN)
• Metallurgy (steel, non-ferrous alloys, ceramics)
• Ceramics, Catalysts, and Minerals

Advanced Functionality & Usability:

• High-Temperature Impulse Furnace – Efficiently extracts hydrogen as H₂ gas, ensuring accurate quantification.
• Real-Time Measurement Display – Shows extracted gas signals as curves and numerical values.
• Automatic Data Saving & Management – Graphs and data are automatically saved for easy review and analysis.
• Maintenance Navigator – Provides visual guidance for routine maintenance, enabling any operator to perform maintenance tasks with ease.
