GENERAL GAS ANALYSIS Method
MA-1105
Samples may be collected in aluminised bags or other suitably prepared containers such as gas cylinders.
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.

SULPHUR GAS ANALYSIS Method
MA-1113
Samples should be collected in aluminised 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 aluminised 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.
