Scope

Main technical content: I. Methodological Principles After the sample is extracted and shaken with the extraction solution, it is detected using a portable mass spectrometer. The instrument software compares the test results with the built-in standard spectral library of 31 health products to determine the test results: displaying the test results and determining whether they are negative or positive. II. Reagents and Materials 2.1 Dropper bottle containing the extraction solution (ethanol: acetonitrile: formic acid = 180:20:1). 2.2 500μl EP tubes. 2.3 0.22μm organic nylon filter membranes. 2.4 Sampling spoons. III. Sample Preparation Use a disposable sampling spoon to take a spoonful of sample and place it in the extraction solution. Shake with a vortex shaker for 1 minute or vigorously shake for 1 minute. Then, squeeze the extraction solution from the dropper bottle through the 0.22μm organic nylon membrane into a 500μl EP tube. IV. Analysis Steps 4.1 Turn on the power and start the molecular pump for about 5 minutes. 4.2 Secure the capillary column, fix the blank reagent, clean it 5 times, and then replace it with the sample to be tested and clean it 10 times. 4.3 Select "Health Product Detection", select the category, enter the sample number, and then start the test. After the analysis is completed, the results can be reviewed. V. Result Determination The instrument software compares the test results with the built-in standard spectral library of 31 health products to determine the test results: displaying the test results and determining whether they are negative or positive. VI. Comparative Test Data Compare the results of the rapid detection method with those of the corresponding national standards, industry standards, or validated standard methods.
