- at approximately 30 bar pressure
The gas samples will contain the following components (nominal mole fractions only):
- Ethane: 4 %
- Propane: 1 %
- n-Butane: 0.2 %
- iso-Butane: 0.2 %
- n-Pentane: 0.015 %
- iso-Pentane: 0.015 %

- We will distribute samples by 1 December 2020.
- You must submit your measurement results and return the sample cylinders by 15 February 2021.
Cost
There are 3 price options to participate:
- $1550 if we supply sample cylinder at 30 bar, and you return it after testing
- $5100 if we supply a sample cylinder at 100 bar and you keep the sample to use as a calibration standard
- $5750 if we supply 2 cylinders—a calibration standard and a sample—and you return the sample after testing
