- 摘要:
- 利用速测仪RP-420及气相色谱7890A-FPD 对一定数量的蔬菜样品进行检测。结果表明：经速测仪检测农药残留超标的20份蔬菜，再经气相色谱检测后有17份蔬菜有农药残留检出，检出率达85%，其中有3份超标，超标率达15%。说明利用速测仪对农贸市场或蔬菜批发市场蔬菜进行初步检测，是很必要的，既可以节省检测时间又可以节省检测费用。同时，相同的蔬菜品种虽经速测仪检测均属农药残留超标品种，但经气相色谱检测后发现其检测结果差异很大，说明利用气相色谱对农药残留超标蔬菜进行再次检测，对保证检测结果的准确性是很重要的。
- 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.
