摘要:以番茄汁中克百威的检测为例,将对比教学法应用于高效液相色谱仪(HPLC)和液相色谱-质谱联用仪(HPLC-MS)的实验教学中。在理论教学部分,对比两种大型仪器的原理、构造、应用特点及其在克百威检测中的异同。在上机实操部分,由于番茄汁中的克百威含量低于HPLC 法的检出限但高于HPLC-MS 法的检出限,两种仪器得出截然不同的检测结果。对比教学法切实提高了实验教学效率,提升了学生的大型仪器综合运用能力,对高校应用型人才的高质量培养具有重要意义。

Abstract: The comparative teaching method was applied in the experimental teaching of High Performance LiquidChromotography(HPLC)and High Performance Liquid Chromotography-Mass Spectrometry(HPLC-MS)by takingthe determination of carbofuran in tomato juice as an example. In the theoretical teaching part,the similarities anddifferences of the discipline,structure,application in the determination of carbofuran between HPLC and HPLC-MSand their determination of carbofuran were compared. In the practical operation part,different results were given byHPLC and HPLC-MS since the carbofuran content in tomato juice was lower than the detection limit of detection ofHPLC method but higher than that of HPLC-MS method. The teaching efficiency and the comprehensive applicationability of students for large-scale instruments were increased substantially by the comparative teaching method,whichis meaningful to the application-oriented talent cultivation in colleges and universities.
