Teaching method for integration of chemical experiment and chemical test of trace medicines

The invention provides a trace pharmaceutical chemistry experiment and assay integrated teaching method, which comprises the following steps of: using a trace (ul-level) disposable reaction container and a trace (ul-level) reaction measuring vessel; normal temperature or water bath heating chemical experiment reaction is used, a quantitative sample application capillary tube is used for extruding air into a melting point tube with reaction liquid for bubble stirring, the reaction time is shortened by three quarters, and thin layer chromatography is directly carried out on the reaction liquid after the reaction is finished or after the reaction liquid is dissolved by an organic solution. Students carry out thin layer chromatography on sample contrast initial reactants and teacher reaction products, and the result is photographed, compared and analyzed. Separation and simulation of related substances are close to an impurity experiment: students scrape off a related substance reference substance from a silica g
