What is an LNG Sampling System Inspection?
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.
This service is now covered by EffecTech’s ISO/IEC 17020 scope for inspection.
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 vaporisation
- GC repeatability in line with the requirements of EN 12838 for the measurement of vaporised LNG. Based on this data, a Monte Carlo simulation is run, which will identify a safe operating envelope to ensure homogeneous sampling or vaporising.
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 vaporiser, EffecTech offers
- ISO 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.
