Influence of process parameters on the composition of gaseous standard mixtures of n-propanethiol obtained by thermal decomposition of surface compounds.
A method for preparation of gaseous standard mixtures of n-propanethiol based on thermal decomposition of surface immobilized compounds bonded to silica gel is described. On the basis of the experimentally established relationships between n-propanethiol concentration and generation time, the influence of the mixture composition on diluting gas flow rate, decomposition temperature, and surface compound bed mass was determined.
