Most of the ultrapure water used in laboratories has relatively high requirements for water quality. According to different applications, it can be divided into three levels of water. The first level of water has a resistance requirement greater than the conductivity and a lower conductivity. It is mainly used for analytical tests with strict requirements, including for particles. Required testing. Such as high pressure liquid chromatography analysis of water. Primary water is commonly produced by secondary water that has been distilled by quartz equipment or treated by reverse osmosis and ion exchange mixed beds, and then filtered through microporous membranes. Secondary water, the resistance requirement is greater than the conductivity and is mainly used for inorganic trace analysis and other tests, such as atomic absorption spectrometry water. Secondary water can be produced by multiple distillation or reverse osmosis and ion exchange methods. Grade three water is used for general chemical analysis tests. Tertiary water can be produced by distillation or ion exchange.
