OBJECTIVE: To determine the conditions of substance abuse using the same GC-MS GC-MS with confiscated substances. Methods: By selecting different injection port temperature, carrier gas flow rate, starting temperature of the furnace, the program heating rate, the temperature of the end of the temperature and the holding time, the detection of the same substance abuse, the detection of different testing conditions on the detection of substance abuse The impact of optimizing test conditions. Results: Different test conditions have a certain influence on the retention time, peak shape and peak area of substance tested. Conclusion: The optimal conditions for the detection of substance abuse by gas chromatography / mass spectrometry are as follows: the detector is a mass spectrometer, the temperature is 280 ℃; the scanning mode is Scan; the temperature of the inlet is 250 ℃ ~ 280 ℃; the carrier gas flow rate is 0.8ml · min-1; the temperature of the furnace is programmed temperature, the starting temperature is 80 ℃ ~ 100 ℃, the program heating rate is 5 ℃ · min-1 ~ 10 ℃ · min-1, the temperature of the final temperature is 300 ℃, the holding time is 10min ~ 15min.
