Some combustible gases, like natural gas, are colourless and odourless and are difficult to detect in its natural state. Odorization is the process of injecting an odorant into a combustible gas in a pipeline so that it is detectable by smell. Regulations require odorization in exact quantities, to detect every leak, no matter how slight, during distribution, reloading or transport.

Gas sampling is conducted to characterize the thermal, chemical and hydrological properties of a surface. Various methods are applied to obtain samples used for the determination of the composition of gases.
