To establish the GPC - GC - MS detection method for determination of organochlorine pesticide residues in milk powder. After simple processing samples, concentration with multi-position concentrator, and online cleaning with GPC-GC-MS, injection into the mass spectrometer for analysis. Results showed that in the linear range of 5～100 ug/L, the correlation coefficient were >0.998, and the method detection limits (MDLs) were <0.5 ug/kg. The spiked recoveries at three levels of 10, 50, 100 ug/kg were in the range of 70 ~ 95%, the relative standard deviations (RSDs) (n=6) were<10%. This method had advantages of good accuracy and precision, simple operation, rapid, and was suitable for routine analysis.
