Calibration gas, also known as a calibration gas mixture, is generally a compressed mixture of gases or gaseous components. Calibration gases are used as comparison standards in the calibration of many instruments. They ensure that instruments such as gas analyzers or gas detectors read correctly.

Fine Gas along with its associate Air Products offers complete range of gas mixtures that are primarily used for checking and calibrating the function of detectors and instruments used in the following applications:

  • Flammable gas detection
  • Toxic gas detection
  • Refrigerant gas detection
  • Ethanol breath testing
  • Gas chromatography
  • Food atmosphere analysis
  • Medical gas analysis
  • Environmental monitoring

The portfolio of available mixture types covers the whole range from simple LEL binary mixtures through to laboratory standards featuring complex blends of multiple components at low ppm levels and use where accuracy, stability and reliability are a must.

Gas mixtures are available in two modes of supply, the traditional refillable cylinder as well as non-refillable canisters.

Mixtures in traditional cylinders can be supplied to the most stringent customer specifications, including parts per billion concentrations and certification up to ISO 17025 with stability levels of up to 120 months. These features ensure suitability for almost all user requirements and applications.

Non-refillable canisters, typically used where low gas volumes are required, have unrivalled stability levels for both reactive and non-reactive components and are available with short delivery times.

Fine Gas can offer complete range of Calibration gases in small non refillable cylinders to traditional 50Ltr refillable cylinders with complete certification as per customer’s requirement.
