This thesis contains the developed methodology for defining tributyl phosphate and di-2-ethylhexylphosphoric acid by gas chromatography method in their coexistence in aliphatic hydrocarbons dilution. The optimal conditions for analysis were determined. Moreover, while research the need of using the internal standard for getting more accurate results was found. The metrological characteristics of established research were defined.
