It is not only important to have the correct quality of gases, it is equally important to handle the gases by using equipment most suited for the application.
Sources of Error When Transferring Gases
Reduction in component concentrations – increase in Absorbent Surface Area
ERROR Employment of unsuitable material
IMPACT Chemical Reaction, especially in the presence of moisture.
Reduction in Assayed Components Contamination through undesired components
ERROR Ad/Desorption on surface area.
IMPACT Gas molecules are given off in the gas stream. Components adhere to the surface area.
Pure gas is constantly being contaminated
ERROR Line leaks.
IMPACT Partial pressure gradients between different gases force gas molecules towards the side with lower partial pressure, regardless of pressure.
Irregular contamination of pure gas, reducing after an extended period of withdrawal
ERROR Dead volume is not taken into account
IMPACT Pressure drifts as well as the motion of the molecules themselves; contaminate the pure gas stream with foreign gases from the dead area.
Contamination of pure gas increases as hose length increases and temperature rises
ERROR Permeation through hose walls.
IMPACT Even after the first purge, foreign gas molecules enter the stream of gas (H₂O, CO₂, HC, etc)
