High Purity Gases

High Purity Nitrogen (N₂)

Nitrogen in purity grades 4.5 to 6.0 for moisture- and oxygen-sensitive applications such as gas chromatography, LC-MS and electronics manufacturing.

Product Description

Thanks to its colourless, odourless and inert nature, high purity nitrogen is the most widely used gas in analytical instruments and sensitive production processes. Nitrogen purity and impurity levels can affect chromatography, sample preparation and electronics processes. Suitability should be verified using the relevant technical specifications. We define the purity grade your application requires together with you and supply it in cylinders or bundles.

Key Features

  • ✓Supplied in grades 4.5, 5.0, 5.5, 6.0 (99.995% – 99.9999%)
  • ✓Inert nature that prevents oxidation and moisture-related deviations
  • ✓Certificate of Analysis (CoA) for every batch
  • ✓Shipment in compliance with ADR rules and high-pressure safety standards

Usage Areas

Carrier and make-up gas for gas chromatography (GC)
Nebulizer and drying gas for LC-MS instruments
Inert atmosphere in electronics and semiconductor manufacturing
Inerting in sample preparation and nitrogen evaporators

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: Nitrogen 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.
