What safety matters should we pay attention to when using chemical reagents and using analytical instruments?
General workshop control analysis, selection of analytical pure chemical reagent. Any preparation, experiment, cooling bath, or heating of a drug. Optional industrial products.
In the sample with a large number of pH, the pH should also choose excellent chemical pure. At the same time, the preparation method of the purified water and the washing method of the glassware are also required,. The analysis also used as analytical reagent, gr.
The selection of chemical reagents should be based on analytical requirements, including analytical tasks, analytical methods, and accurate results. Different grades of reagents should be used. If you want to use high purity or guaranteed reagent trace analysis, in order to reduce the blank value and avoid the interference of impurities.
