What are the requirements of the water used for laser diffraction particle size analysis?

2023-01-19WIKI

According to the demand of the application, distilled water, purified water, deionized water, clean tap water, and well water can be used as media for particle size measurement. No matter which kind of water is used for measurement, it should be pure without impurities. The water temperature should be as close to room temperature as possible, especially higher than the dew point temperature, in case the sample cell becomes foggy.

 

When using tap water or well water as the medium, it should be placed in a container inside the laboratory for at least 24 hours before use. The reasons are that the impurities will precipitate, and the water temperature will be closer to the laboratory room temperature, especially after a long period of storage.
