The limitation of the ISO standard is that it is only applicable for laboratory analysis type gas chromatographs. Calibration Gases Gas chromatography sio 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.

Operators require this to demonstrate that their natural gas measurement systems are operating as expected and that optimal performance is being maintained reducing signifi cant mis-measurements which may compound over time leading to large financial discrepancies. Improvement of hydrocarbon dew point determination via gas chromatography. Take the smart route to manage medical device compliance.

These standards, which currently underpin the use of gas chromatography for gas quality measurement form the basis of many commercial contracts. One important characteristic of the gas chromatograph, is that the measurement of carbon fractions greater than pentane, n – C5, is based on the relationship of component elution time and hydrocarbon boiling point.

In addition, we provide physical properties according to ISOhydrocarbon dewpoint to ISO and other combustion properties such as carbon emission factors. EffecTech also holds ISO All rights reserved Opt Out of Google Analytics. Learn more about the cookies we use and how to change your settings.

Flow Validation Services EffecTech specialises in performing ISO accredited calibrations and validations of the secondary elements of any gas fl ow metering system. This enables EffecTech to provide clients with evidence of compliance with even the strictest fiscal metering requirements.

UKAS provides accreditation to conformity assessment bodies that carry out conformity assessment in accordance with standards. It is important to us that you purchase the right document. This accreditation covers the analysis of natural gas from customers’ sites to determine the physical properties of the gas — Natural Gas Analysis.

Gas chromatographic requirements for hydrocarbon dewpoint calculation Status: The reason for this, is that the process type gas chromatograph does not have a method to identify these species between the normalised alkane components in the C6 to C8 carbon groups.

As part of its commitment to staff development, EffecTech has successfully maintained its Investors in People IIP accreditation for over five years. Search all products by. We also witness metering validations as an independent third party. 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.

EffecTech offers a troubleshooting and consultancy service to investigate and identify metering errors, lost or unaccounted for gas and suspected metering or energy imbalances across plant and hydrocarbon accounting chains. Regular site Inspections and performance evaluations provide confidence in the metering system and objective evidence that the gas is being metered correctly. We ensure you receive the best solution for your application, drawing on years of experience in gas metrology.

Organisations that have successfully achieved accreditation to ISO standards have demonstrated their competence through an independent third-party review by their accreditation body. ISO — Testing View accreditation schedule This accreditation covers the analysis of natural gas from customers’ sites to determine the physical properties of the gas — Natural Gas Analysis.
