Abstract
An apparatus and method to convert high resistivity (18 MOhm/cm) deionized water into lower resistivity deionized water with a tight resistivity range (150 KOhm/cm+\−50 KOhm/cm) without adding metals to the DI. The invention discreetly injects carbon dioxide in an on demand fashion through a metals free fluid path.
