Grygorcewicz, Jon-Paul Frederick Improvement of hydrocarbon dew point determination via gas chromatography. Regular site Inspections and performance evaluations provide confidence in the metering system and objective evidence that the gas is being metered correctly. Flow Validation Services EffecTech specialises in performing ISO accredited calibrations and validations of the secondary elements of any gas fl ow metering system.

We ensure you receive the best solution for your application, drawing on years of experience in gas metrology. The limitation of the ISO standard is that it is only applicable for laboratory analysis type gas chromatographs.

It can take many forms. Due to the inherent design of the process type gas chromatograph there are limitations to the computation of the gas mixture in the C6 to C8 carbon groups. Typical customers are large consumers of gas such as power stations and producers including gas transmission and LNG terminal operators where the end user does not own and maintain the fl ow measuring equipment. This enables EffecTech to provide clients with evidence of compliance with even the strictest fiscal metering requirements.

The International Standard Organistation standard ISOuses this relationship to calculate the boiling points of unidentified hydrocarbon components by linear interpolation between the normalised alkanes. Calibration Gases Gas chromatography and gas analysis is a comparative method and as a consequence the calibration gas is the principal driver for the accuracy of the analysed gas composition, and that of any physical property calculated from it.

Our ISO accredited calibration gases ensure accurate and traceable calibrations through an unbroken chain of measurements back to the SI unit amount of substance, the mole.
