APPARATUS FOR GAS-CHROMATOGRAPHIC ANALYSIS OF MULTICOMPONENT MIXTURES Russian patent published in 1997 - IPC

Abstract RU 2092835 C1

FIELD: analytical chemistry, in particular gas chromatography; environmental control. SUBSTANCE: proposed apparatus comprises, connected in series, metering device, multi-section built-up chromatographic columns including sections with stationary unlike-polarity phases, and detector of type other than mass-spectral detector. Separating column and unit for isolating individual band are interposed, in series, between metering device and multi-section chromatographic column. In parallel to first detector, mass-spectral Vicjofy detector is arranged to service chromatographic columns. One of outputs of separating column is connected to inputs of detectors. proposed apparatus can be used in laboratories of chemical plants, in research laboratories, for analysis of contaminants for environment, for analysis of medicinal preparations, pesticides, oil processing products, etc. EFFECT: proposed apparatus is multi-purpose one and can be used in number of applications. 1 dwg
