摘要
随着人类对食品要求的提高,农药残留检测技术在食品中应用越来越普遍,气相色谱仪和质谱的联用技术被广泛使用,多数的使用者只能够熟练操作气相色谱-质谱联用仪,但使用中对应特别注意的问题、气相色谱-质谱联用仪的日常保养和维护的知识了解很少。而农药残留等分析数据的准确可靠,仪器的状态是一个及其重要的影响因子,正确合理的使用与维护保养不但可以确保仪器的状态良好,而且可以让仪器和易耗件的使用寿命延长。
With the improvement of human demands for food, Pesticide residue detection technology applied in the food more and more common, Gas chromatography and mass spectrum detection is widely used, but the knowledge that we should pay special attention to some of the problems in use, the daily maintenance of the instrument is known very little. But for the accuracy and reliability of the data analysis, equipment status is a very important factor, the correct use and maintenance can not only ensure equipment in good condition, can also extend the service life of equipment and consumable.
