High Purity Gases

High Purity Helium (He)

Helium in purity grades 4.6 to 6.0 for gas chromatography, leak testing and semiconductor manufacturing.

Product Description

Helium may be used as a carrier gas in gas chromatography and compatible GC-MS systems. Performance depends on instrument requirements and gas specifications. Because of its small atomic size, it is used as a tracer gas in leak testing and as an inert atmosphere gas in semiconductor and optical fibre manufacturing. We supply it in cylinders or bundles according to the purity grade your application requires.

Key Features

  • ✓Supplied in grades 4.6, 5.0, 5.6, 6.0 (99.996% – 99.9999%)
  • ✓Low background and stable vacuum in GC-MS systems
  • ✓Certificate of Analysis (CoA) for every batch
  • ✓Shipment in compliance with ADR rules and high-pressure safety standards

Usage Areas

Carrier gas for gas chromatography (GC and GC-MS)
Helium leak testing
Inert atmosphere in semiconductor and optical fibre manufacturing
Research laboratories and analytical instruments

Supply and Storage Models

1. High-Pressure Cylinders

Supplied in cylinders suitable for high purity gas service, for the daily consumption of laboratories, R&D centres and analytical instruments. The purity grade and cylinder type are defined together according to your needs.

2. Cylinder Bundle Systems

Manifold-connected cylinder bundle systems may be considered for high gas consumption facilities in terms of flow rate, pressure, and cylinder replacement planning. Suitable capacity and backup requirements should be determined for each project.

Safety Standard

Technical Warning and Safety Standard: Helium is not toxic, but it displaces oxygen and creates a risk of asphyxiation in confined spaces. Cylinders must be stored upright, secured and in well-ventilated areas; to maintain high purity, only clean and suitable regulators and line components should be used.
