Abstract:: Rapid Test Instrument RP-420 and Gas Chromatography 7890A-FPD were used to test some vegetable samples.The results showed there were 20 vegetables that the pesticide residues were exceeding the limit when testing by Rapid Test Instrument，then，using the Gas Chromatography 7890A-FPD to test the 20 vegetable samples again，the results showed there were 17 vegetables that had pesticide，the rate of detection was up to 85%，and there were 3 vegetables among them that the pesticide residues were exceeding the limit，the rate of exceeding limit was up to 15%。At the same time，the tested results that had been detected by Gas Chromatography had difference.Therefore，Rapid Test Instrument was used to go preliminary test was very important，it can economize time and fee，and in order to ensure the accuracy of test results，gas chromatography should be used to test the vegetables again.
