Several Common Extraction Methods
In chemical analysis, the general requirement of analytical instruments is the state of solution, so extracting the substances to be measured from solid and semi-solid into solution is a process that almost all methods will encounter. In fact, in our daily life, the extraction process occurs all the time, such as making tea, boiling chicken […]
Common Purification and Separation Methods in Laboratory
Purification refers to the purification of the mixture to remove its impurities and obtain the main substance in the mixture. The purified impurities do not need to consider their chemical composition and physical state. There are many separation methods for mixtures, but according to their separation nature, they can be divided into two categories: 1. […]
