Abstract
Sample handling and analysis procedures have been developed for the verification of soman, sarin, triethyl phosphate and mustard in contaminated paint, concrete, and rubber. Triethyl phosphate and mustard were generally recovered from the sample media with efficiencies greater than 65%. Soman was usually recovered with slightly less efficiency (20% to 60%) and sarin was recovered in the lowest yield (5% to 40%). Each extract was quantitatively analysed by capillary column GC-FID and confirmation of all spiked chemical agents was performed by capillary column GC-MS. The developed methods were successfully applied during the 1991 United Nations sponsored round robin analytical exercise. Defence Research Establishment Suffield, the designated Canadian laboratory, positively confirmed all the spiked mustard related compounds in the samples provided for round robin analysis and did not detect any artifacts or false positives in the samples.
