Abstract: Different techniques of Glow Discharge AES are described in this paper. Themost important parameters at such investigations are: the power of VHF-field,pressure of the inert gas and concentration of the easily ionizable additive,e.g. NaCl. The influences of these parameters were studied It is proposed ahigh sensitive flash desorption method, which enables investigation of thewater desorption rate from humidified samples of biological origin, namely DNAand chromatin. The ways of minimizing of detection limit are considered as themost important characteristics of an analytical device. The concentration ofany measured element is detectable if it correlates to the signal equal totripled standard deviation of the results of background measurement. Electrontemperature of the Helium has been evaluated by absorption rate at two lines ofhelium \lambda=353.828nm; \lambda-=344.759nm that was equal to T c ~ 15000 K.
