Two classes of contaminants, inorganic salts and dissolved organics, are known to affect most laboratory experiments and it is therefore important that they are monitored online in laboratory water systems.
Lab Water Grades
Norms define different laboratory water grades for both technical and economical reasons. The purpose of these norms is to ensure that the right water quality is used for a specific application, while limiting laboratory operating costs - Type 1 water is more expensive to produce than Type 2 or Type 3 water.
Using Type 1 water for Type 2 water applications is a common laboratory practice in order to decrease the risk of artifact generation during experimental procedures.
