Testing and detection of arsine, phosphine, and ammonia in liquid petroleum gases (LPG) and natural gas.

Arsine, phosphine, and ammonia trace level content in liquid petroleum gases (LPGs) and natural gas can be tested by select Intertek laboratories, using the dry colorimetric detector method.

When found in natural gas, arsine, phosphine, and ammonia levels can contribute to the poisoning of gas processing catalysts.  

The LPG and natural gas analysis laboratories also analyze for hydrocarbons and non-hydrocarbon gases and compounds in gaseous mixtures by gas chromatography, using ASTM D7833 and other industry and in-house test methods.
