Standard gas mixtures (SGM) are indispensable reference materials for ensuring the reliability of analytical work. Reference materials are an excellent tool for the quality control and assurance of analytical results. Standard gas mixtures are unique among reference materials. The rapid progress of SGM production is connected with the instability of gaseous analytes which make them difficult to obtain. The use of standards with matrix compositions and analyte concentrations resembling those of environmental samples enhances the reliability of analytical results. The increasingly frequent analysis of representative samples of various gaseous media is stimulating demand for new techniques of preparing standard gas mixtures, which in certain cases act as matrix-free reference materials. The field of standard gas mixtures has for a number of years now witnessed rapid advances in methodological approaches for producing matrix-free reference materials. Among the available static and dynamic techniques for preparation of standard gas mixtures, the thermal decomposition of a surface compound has recently gained in popularity. At the Department of Analytical Chemistry of the Gdańsk University of Technology research on the application of thermal decomposition techniques for obtaining standard gas mixtures has been in progress for a 25 years.
