Composition

EffecTech’s calibration gas design takes into account the following to deliver the optimum gas mixture for your measurement needs.

• Variation of stream gas composition
• Operational temperature and pressure
• Accuracy needed to make it fit for purpose

Maximising gas volume

Proposed designs will also maximise cylinder fill pressures, where appropriate, through gas liquid phase equilibrium calculations so you receive the highest gas volume possible within the required parameters.

Physical properties

Physical properties for all natural gas calibration mixtures are included on certificates of calibration. These can be used for measurement confirmation as part of your quality control procedures and validation.

Physical properties of calorific value, relative density, real density, Wobbe index, mean molar mass and compression factor are calculated from composition according to ISO 6976, GPA 2172 or ASTM D3588.
