The invention discloses a sample preparation device for derivatization reaction of dairy products, and particularly belongs to the technical field of detection. The sample preparation device comprises an upper fixing rod, a hollow lower fixing rod, a containing cylinder, a driving device and a shaking device for driving the containing cylinder to shake left and right. The driving device comprises an ejector pin air cylinder, a sliding column, a first connecting rod, a first transmission toothed plate, a first transmission wheel, a second connecting rod, a first transmission belt, a second transmission wheel, a fixing frame and a telescopic connecting rod. The sample preparation device has the advantage that sample liquid and a derivatization reagent can be fully and uniformly stirred.
Description
technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a sample preparation device used in the derivatization reaction of dairy products. Background technique [0002] When detecting and analyzing dairy product samples in the laboratory, certain compounds usually need to undergo a chemical reaction with certain chemical reagents under specific conditions, and the target compound in the dairy product sample is prepared into an appropriate derivative, and then chromatographically Perform separation testing. Different compounds require different derivatization reaction conditions, such as high temperature, water bath or freezing. During the derivatization reaction, it is necessary to fully stir the derivatization reagent and the sample, so as to prepare standard derivatives. [0003] Common dairy product testing samples include cow's milk, goat's milk, camel's milk, etc. However, when experimenters use milk samples prep...
