EffecTech offers an LNG sampling system inspection service in accordance with ISO 8943 to enable customers to check that their sampling systems are fit for purpose under a full range of conditions.
An experienced EffecTech gas quality engineer will complete a full inspection of the LNG loading sampling system against the requirements of ISO 8943.
The inspection reviews the following:
- The enthalpy of sub-cooling for homogeneous sample vapourisation
- GC repeatability in line with the requirements of EN 12838 for the measurement of vapourised LNG. Based on this data, a Monte Carlo simulation is run, which will identify a safe operating envelope to ensure homogeneous sampling or vapourising.
A detailed compliance report is provided, highlighting any recommendations for change and adjustments based upon the findings.
For customers who measure LNG using a gas chromatograph and vapouriser, EffecTech offers
- 17020 accredited inspections and ISO 17025 accredited calibrations in accordance with ISO 10723 for LNG and natural gas
- high quality traceable ISO 17034 Certified Reference Materials, which provide the amount mol fraction and uncertainties for methane, as well as all the other components.
- LNG Sampling System Inspections

What are the issues with LNG sampling?
Pre-vapourisation and enrichment occur when the LNG sample is not completely vapourised in a single step.
