METHOD OF DETERMINATION OF BETA-CHLOROVINYL DICHLOROARSINE IN AIR WITHIN LEVEL OF MAXIMUM ALLOWABLE CONCENTRATION Russian patent published in 2000 - IPC

FIELD: analyses of nonbiological materials by physical and chemical methods. SUBSTANCE: method may be used in assessment of depth of distribution of hazardous concentrations of beta-chlorovinyl dichloroarsine at objects of chemical weapon destruction, and in solving problems of ecological monitoring. Sampling tubes are filled with glass balls whose surfaces are coated with polyethylene glycol. Method includes gas chromatographic analysis of acetylene liberated in alkaline hydrolysis of beta-chlorovinyl dichloroarsine. EFFECT: simplification of process by method of sampling with reduced consumption of materials, time and labor with preserved high sensitivity and accuracy of determination. 4 tbl, 1 ex
