CHROMATOGRAPHIC METHOD OF SEPARATING AND ANALYZING MIXTURES IN GASEOUS PHASE Russian patent published in 1995 - IPC

FIELD: gas chromatography. SUBSTANCE: components of the mixture are ionized preliminary, and positively and negatively charged fraction of ions are separated. Each separate fraction is directed to its special column for subsequent component-by-component separation. Gas is used as movable phase, which gas has ionization energy to be higher than ionization energy of components of the mixture. In specific cases, not all the components of the mixture are subjected to ionization, but single pair of components which is separated hardly, or only single component of the pair. EFFECT: widened capabilities of chromatographic method of separation. 3 cl, 2 dwg
