This proficiency test is part of the National Measurement Institute's (NMI's) 2023 proficiency testing program for gas mixtures.
Registrations close 1 June 2023.
We will supply each sample:
- in a 5 L gas cylinder
- with a AS2473 Type 20 outlet
- at approximately 25 bar pressure
The gas samples will contain the following components (nominal mole fractions only):
- Nitrogen ≤ 30 %mol/mol
- Methane ≤ 30 %mol/mol
- Hydrogen (Balance)
- Mixture may contain trace amounts of other process gases such as hydrocarbons and carbon dioxide
Sample distribution and reporting
- We will distribute samples by 1 August 2023.
- You must submit your measurement results and return the sample cylinders by 1 October 2023.
