Gas Analysis Services

GENERAL GAS ANALYSIS Method MA-1105 Samples may be collected in aluminised bags or other suitably prepared containers such as gas cylinders. A sample volume of 4 litres or more is required. Carbon monoxide is confirmed by infrared analysis. If less than 4 litres of gas is supplied the lower reporting limit is 0.001% Ranges indicated may vary depending on actual gas compositions. Turnaround time for General Gas Analysis is typically 12 working days from receipt in our laboratory. Components Range - % by Vol Helium 0.001 - 100 Hydrogen 0.001 - 100 Carbon Dioxide 0.01 - 100 Ethylene 0.002 - 0.1 Ethane 0.002 - 10 Oxygen 0.1 - 20.9 Nitrogen 0.1 - 100 Methane 0.01 - 100 Carbon Monoxide 0.0005 - 100 SULPHUR GAS ANALYSIS Method MA-1113 Samples should be collected in Tedlar bags. The gas should be dried prior to collection. This involves passing the gas through an anhydrous sodium sulphate drying tube. If required, we can provide prepacked drying tubes and tedlar sample bags for a fee. Samples should be submitted immediately after collection for analysis. A gas sample volume of 500 ml or more is required. If elevated H2S levels are present, reporting limits for the other compounds may be raised. The laboratory requires a minimum of 2 days notice prior to receipt of samples. Turnaround time is 12 working days from receipt in our laboratory. Components Range - ppm Hydrogen Sulphide 0.2 - 500 Carbonyl Sulphide 0.2 - 500 Ethyl Mercaptan 0.2 - 500 Methyl Mercaptan 0.2 - 500 Sampling Procedures & Media form an integral part of obtaining reliable results. We work with our clients to ensure the sampling & analytical techniques satisfy the “data quality objectives”. In addition, we are able to prepare and supply the right, solid sorbent tubes, gas bags and canisters for sampling.
