果蔬有机磷农药残留检测中的温度控制研究
Temperature control during determination of organophos- pbete pesticides residue in fruits and vegetables
【摘要】 为了给便携式农药残留检测仪研究开发提供温度控制单元的方案,深入研究了环境温度、水浴温度和比色池温度对农药残留检测结果的影响。结果表明,对以酶抑制法为原理的农药残留检测方法和仪器,温度控制方式不仅影响分析结果的准确度,而且还影响分析结果的灵敏度。在仪器比色池中采用恒温的方式不仅可以提高分析方法的灵敏度和准确度,还可以提高仪器的最低检出限。
【Abstract】 In order to provide a temperature control design for a portable device for determination of organophosphate pesticides residue, the effect of temperature on the determination of organophosphate pesticides residue has been studied in this paper. The results showed that the temperature could not only affect the accuracy but also the sensitivity of the analysis. Control of the cell in the colorimetric device can improve the accuracy, sensitivity and the limit of detection.
