Description
本发明涉及一种医学检验设备，尤其涉及一种用于皂化回流充氮保护装置。The invention relates to a medical testing equipment, in particular to a nitrogen filling protection device for saponification backflow.
在使用国家标准方法进行维生素E的检测时，需用皂化回流提取，且在皂化回流装置中需要充氮气保护，国家标准中只提到了充氮气保护，但未具体说明如何进行充氮气保护。给实际检测工作带来诸多不便，不同实验室采用了多种不同的方案，起到一定的作用，但操作不太便利，比如：从冷凝回流管顶端放置长玻璃管至圆底烧瓶口处；使用充氮气的气球套在冷凝回流管顶端等。有的实验室甚至不进行氮气保护，直接进行试验，采用回收率校正后报告检测结果。这些方案起到了一定作用，但数据的准确性会大打折扣。据了解，目前市场上还未有一款较为合适的器皿或耗材能够应用到皂化回流过程中，作为充氮气保护的装置。When using the national standard method for vitamin E detection, saponification reflux extraction is required, and nitrogen protection is required in the saponification reflux device. The national standard only mentions nitrogen protection, but does not specify how to perform nitrogen protection. It brings a lot of inconvenience to the actual testing work. Different laboratories have adopted a variety of different schemes, which play a certain role, but the operation is not convenient, such as: placing a long glass tube from the top of the condenser reflux tube to the mouth of the round bottom flask; Use a balloon filled with nitrogen to cover the top of the condensate reflux tube, etc. Some laboratories do not even carry out the nitrogen protection, and directly conduct the test, and report the test results after the recovery rate is corrected. These programs have played a role, but the accuracy of the data will be greatly reduced. It is understood that there is no suitable utensil or consumable on the market that can be applied to the saponification reflux process as a nitrogen-filled protection device.
