WATER, DEIONIZED

Definition

Deionized water is necessary for performing TSH test with the ELISA reader.

Deionized water is also used in reagent preparation, transferring an analyte within a test procedure, as a calibration standard or analytical blank, and for cleaning laboratory equipment.

Deionization removes minerals and ions, both cations (positively charged ions) and anions (negatively charged ions), through a chemical process. The deionizing process (DI) uses specially manufactured ion-exchange which exchange hydrogen ions and hydroxide ions for dissolved minerals, which are then recombined to form water. This leaves deionized water in an unbalanced condition and with an strong electrical charge.

Deionized water does not significantly remove uncharged organic molecules, viruses or bacteria.
