The goal of this article is to demonstrate that the Shimadzu TOC-VW can effectively oxidize the Humic Acid (HA) matrix at high accuracy and precision levels never before witnessed by the wet chemical TOC community. The Shimadzu TOC-VW Carbon analyzer is the only TOC on the market that uses three oxidation techniques of UV light, heat, and persulfate in a single analyzer.1
