Industrial gas cylinder ALPHAGAZ™ 1

gashydrogencylindrical

Summary
The high-purity gas recommended for laboratory analyses, suitable from % to ppm levels.

Applications

• Carrier gas (GC)
• Instrument gas (flame detectors, thermal analysis, ...)
• Semiconductor industry: carrier gases for doping and epitaxy

Fields of use
ALPHAGAZ™ 1 Hydrogen (H2) is used across routine laboratory analysis: as a carrier gas in gas chromatography (GC), as a working gas for flame ionization detectors (FID), flame photometric detectors (FPD) and thermal analysis. It is also used to create a reducing atmosphere in metal processing and for chemical synthesis.
