Findings (conclusion) n n The research in the area of plasma methods for analysis of substance matter is very important not only for science but also for the industry ; Traditional methods of spectral analysis are possible only in the laboratory. It is impossible to use vacuum analyzers because of their size and operating conditions; The microplasma sensor CES is one of the best alternative options, which can be able to replace big vacuum gas analyzers ; Due to its miniature our sensor can be used not only for the medicine but also for the construction and operation of high-security objects.
