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. Using EffecTech® calibration gases can greatly increase the accuracy of the gas measurements you make. We ensure you receive the best solution for your application, drawing on years of experience in gas metrology. EffecTech® produces calibration gases to the highest international standards according to their scope of accreditation awarded by UKAS. Our ISO 17025 accredited calibration gases ensure accurate and traceable calibrations through an unbroken chain of measurements back to the SI unit amount of substance, the mole. EffecTech® offers ISO 17025 accredited calibration gases for the following applications: LNG, refi nery gas, blast furnace gas, natural gas (up to C10), LPG, mixed refrigerants, trace sulphur / odorant (H2S, COS), stack emission, binary & multi-component (CO, CO2, NO, NO2, SO2 , CH4 & O2). Standard delivery for hydrocarbon mixtures is 2 – 3 weeks, emission gas is 2 – 4 weeks and sulphur mixtures is 4 – 5 weeks to UK or ex works Worldwide.

Inspection of Gas Quality Measurements
EffecTech® provides Inspection and performance evaluations on Gas Quality Measurement Systems & process gas chromatographs in accordance with the international standards ISO 17020 & ISO 10723. 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. Regular site Inspections and performance evaluations provide confidence in the metering system and objective evidence that the gas is being metered correctly. EffecTech® is first in the world to have gained ISO 17025 accreditation for on-site calibration by performance evaluation. This enables EffecTech to provide clients with evidence of compliance with even the strictest fiscal metering requirements.

AnalyticalEffectech_02 Support
EffecTech® has ISO 17025 accredited laboratories which provide high quality analysis, testing and sampling services for natural gas and gas condensate samples. In addition, we provide physical properties according to ISO 6976, hydrocarbon dewpoint to ISO 23874 and other combustion properties such as carbon emission factors. Sampling can be provided by one of our experienced engineers with comprehensive training to local staff for subsequent activities.

Flow Validation Services
EffecTech specialises in performing ISO 17025 accredited calibrations and validations of the secondary elements of any gas fl ow metering system. 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. We also witness metering validations as an independent third party.
