FIELD: analytical chemistry. SUBSTANCE: process of chromatographic separation of vapor-phase mixture includes its injection with eluent into chromatographic column filled with conductive sorbent and formation of difference of potentials between electrodes located in column. Difference of potentials is formed between electrodes located at ends of column and contacting sorbent produced from metal. Zirconium or scandium may be used in the capacity of this metal. EFFECT: improved efficiency and authenticity of chromatographic separation of vapor-phase mixture. 2 cl
