A New Setup for the Measurement of Total Organic Carbon in Ultrapure Water Systems.

With the increasing demand for ultrapure water in the pharmaceutical and semiconductor industry, the need for precise measuring instruments for those applications is also growing. One critical parameter of water quality is the amount of total organic carbon (TOC). This work presents a system that uses the advantage of the increased oxidation power achieved with UV/O advanced oxidation process (AOP) for TOC measurement in combination with a significant miniaturization compared to the state of the art.
