This paper describes the detection limit for 23 drugs and chemicals in the blood by means of a screening method that uses a gas chromatographic system equipped with a wide-bore capillary column and a nitrogen phosphorus detector. The detection limit by this method was determined as being 1 mm of peak height at the detector's range of 100 and 8 of attenuation. Using this scale, the absolute detection limit was in the range of 1 pg for malathion and sumithion to 1 ng for meprobamate. The detection limit of drugs and chemicals in the blood was 5 ng/ml for sumithion to 8 micrograms/ml for meprobamate. Therefore, this screening method is able to detect the presence of drugs even a therapeutic-level dosages, with the exception of compounds such as haloperidol, which have extremely low therapeutic dosage levels.
