title: Application of polar stationary phases OV-225 and OV-275 in the detection of drugs in urine samples.
abstract: A procedure for fast screening of urine sample is described. TLC and GC equipped with NPD enable detection of therapeutic doses of drugs to be made in a short time. Tables of retention values for TLC and GC are also presented. TLC detects drugs with a sequence of three reagents. GC screening is carried out with a temperature programmed run of 30 degrees C/min up to 290 degreesC. For the determination of retention indices new polar phases with suitable thermal stabilities such as OV-225 and OV-275 are used.
