Abstract:
To establish a GC-MS method for determination of pindone in meat products. The effects of ways of extraction and purification on the recovery have been studied. The samples were extracted by acetone and (hexane 11) with dSPE purified column. GC-MS was used for determination by EI. The average recoveries were in the range of 81%~89% at spiked levels of 0.5~5.0 mg/kg. The relative standard deviation of the methods were 3.0%~8.4%, and the limit of quantification reached 0.005 mg/kg which meet the requirement of technical parameters for analysis with fast and simple determination and high sensitivity.
