METHOD OF GAS-CHROMATOGRAPHIC DETECTION OF ETHANOLAMINE IN AIR

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to analytic chemistry, namely to gas-chromatographic detection of ethanolamine concentration in air, and can be applied for sanitary control, for example, of air in operation zone. As sorption system, it is necessary to use solution of sodium carbonate, extragent - toluol, derivation reagent- pentafluoropropionic anhydride in amount 5-7 mm³, and chromatographic analysis is carried out with electron capture detector.;EFFECT: increase of sensitivity, accuracy, reliability of detection, as well as reduction of laboriousness and time for carrying out analysis.;2 tbl
