Process for the essentially uniform impregnation of a bibulous medium with a stabilized reagents system prepared from an iodoplatinate solution and a Dragendorff reagent. The bibulous medium is, thereafter, cured at elevated temperatures and in a moisture-laden environment to insure uniformity of distribution of the reagent mixture and to allow adequate interaction of the reagents in the formation of a stabilized reactive environment within the bibulous medium. Following such curing, the bibulous medium is gradually brought to ambient conditions, packaged in opaque medium and stored in a refrigerated environment. The reactive bibulous medium prepared in the foregoing manner is useful in the selective detection of amphetamine and methamphetamine type drugs in urine and other biological samples. |
