FLAME-PHOTOMETRIC DETECTOR FOR GAS CHROMATOGRAPHY WITH USE OF CAPILLARY COLUMNS

摘要

FIELD: analytical instrumentation, design of flame-photometric detectors for gas chromatography.;SUBSTANCE: detector includes gas burner with gas-feeding conduits for hydrogen and oxygen placed in case, optical filter and radiation receiver. Section of capillary column and upper section of gas burner are located at one level. Burner has inner diameter exceeding inner diameter of column by factor of 5-30 times.;EFFECT: provision for high sensitivity and selectivity.;1 dwg
