摘要 |
FIELD: gas chromatographic devices; chemical industry; oil industry; metallurgy; medicine; biology etc. ^ SUBSTANCE: detector can be used in gas chromatographic device as with filled and empty capillaries and micro-nozzle separating columns for analyzing complex mixtures of matters having as natural and artificial origin. Detector has heater made in form of metal thread, two film thermo-sensitive elements mounted in gas channel at output of chromatographic column in parallel to the heater at similar distance. Thermo-sensitive elements are connected into opposite arms of bridge circuit. Electric current source for the heater has automatic controller to keep temperature and resistance of the source to permanent value. ^ EFFECT: improved precision of detection; improved sensitivity. ^ 2 dwg |
