gas sorption effects : The physical processes whereby some gases are adsorbed onto or desorbed from the surfaces of a solid without transformation of the molecules. 1, record 1, English, - gas%20sorption%20effect
Record number: 1, Textual support number: 1 OBS
The force of attraction between some gases and solids is purely physical and depends on the nature of the participating material. Natural gas can contain several components that exhibit strong sorption effects. Special care should be taken when determining trace concentrations of heavy hydrocarbons, water, sulfur compounds, and hydrogen. 1, record 1, English, - gas%20sorption%20effect

effets de sorption du gaz : Phénomènes physiques d’adsorption ou de désorption observés entre certains gaz et la surface d’un solide sans transformation des molécules. 1, record 1, French, - effet%20de%20sorption%20du%20gaz
Record number: 1, Textual support number: 1 OBS
La force d’attraction entre certains gaz et certains solides est purement physique et dépend de la nature des matériaux en contact. Le gaz naturel peut renfermer un certain nombre de constituants présentant de forts effets de sorption. Il convient de veiller à ces phénomènes, en particulier lors de la détermination des concentrations d’éléments à l’état de traces, comme les hydrocarbures lourds, l’eau, les composés soufrés et l’hydrogène. 1, record 1, French, - effet%20de%20sorption%20du%20gaz

A device to ensure that the sample gas remains at a temperature sufficient to avoid a change of its composition due to condensation of some compounds. 1, record 2, English, - heating%20device
Record number: 2, Textual support number: 1 OBS
Heating elements can be installed on the sample probe and sample lines. In some cases, heating the sample cylinder is also required. It is particularly important where Joule-Thomson cooling occurs as a result of pressure reduction. 1, record 2, English, - heating%20device
Record number: 2, Textual support number: 2 OBS
Heating devices are also used to maintain "wetted surface areas" at near constant temperatures to avoid changes in gas sorption coefficients when measuring components that are prone to strong sorption effects. 1, record 2, English, - heating%20device

Les dispositifs de chauffage peuvent être installés sur la prise de gaz et les lignes de prélèvement, ainsi que, dans certains cas, sur le cylindre échantillonneur.
