When dealing with high purity gas handling, the nature of metallic surfaces in contact with the gas is a major concern because these surfaces are a possible source of gaseous pollution. Several surface treatments may be applied to stainless steel tubes used in gas handling systems, and these lead to different desorption properties. A comparison of the topographical effects accomplished by roughness and SEM measurements, and chemical effects by XPS determinations was made. Results were correlated to the outgassing behaviour of 316‐L SS surfaces, as determined by thermal desorption mass spectroscopy. It appears that similar treatments of 316‐L SS may not result in similar outgassing properties. Electropolished surfaces are smoother and present the least outgassing, although carefully cold drawn and chempolished stainless steel surfaces also show a comparable outgassing behaviour.
