CGM-AIR-2

CGM-AIR-2

CGM-AIR-2 reference standard for calibration gas composition is designed for the verification, calibration, and metrological support of gas-analytical equipment. Based on air, these mixtures contain various combinations of components and guarantee high measurement accuracy for use in laboratories, industries, and metrological services.

These calibration gas mixtures are used for:

  • verification, calibration, and graduation of gas analyzers and measurement systems;
  • monitoring the metrological characteristics of measurement instruments;
  • certifying testing equipment;
  • validation and metrological certification of measurement procedures;
  • internal and external quality control of measurement results.

Concentration Range

The mixtures are prepared with molar (volume) fraction of components ranging from 1×10⁻⁴% to 99.9%.

Standards and Regulations                                                                     

  • ST RK 2.442 — Procedure for measuring the volume fraction of components in gases and gas mixtures using gas chromatography;
  • ST RK 2352 — Calibration gas mixtures: Technical specifications.
  • Production is based on technical documentation of ""JV Oxygen"" LLP
