摘要：
Various methods are studied for preparing stable gas mixtures with trace amounts of volatile substances based on a buffer effect of heterogeneous systems and implemented into headspace analysis, that is, static and dynamic versions of gas extraction. Information is provided on certified procedures for preparing such mixtures, that is, vapor-phase sources of gas mixtures included into the State Register of Measuring Instruments.
