Identification of the contents and shelf-life of field kits for the detection of organophosphorus compounds in the air

Eleven sets of glass indicator tubes for detection of organophosphorus compounds in the air were analyzed for their content and tested on their shelf-life. Sets of tubes were integral parts of army field kits found on the territory of Croatia during the 1991/1992 war. The sets were denoted with serial numbers and dates of validity expiration (from 1974 to 1992) but without statement on the content and manufacturer. Glass tubes were identified to contain a cholinesterase preparation, a non-thiocholine substrate of cholinesterase and a pH-sensitive indicator. Their functioning was tested by use of dimethyl dichlorovinyl phosphate (DDVP). All tested sets were found to be valid for detection which indicated a long shelf-life of the field kits.
