Whatever the structure of the testing service provider, the manufacturer must be satisfied that their partner can deliver the project turnaround, quality, scope of services, reliability, and ultimately, the value that they need.
Technology-specific testing methods in relation to the American National Standards
Bacteria are the most abundant organisms on the planet. It is estimated that they have been in existence 3.5 billion years. These fascinating little creatures are responsible for many of the functions that allow Earth to sustain other forms of life. The health of our planet ultimately depends on their activities as they dwell everywhere throughout the planet such as in the soil, in food, on plants, in our bodies, in the waters and way deep within the Earth.
I thought I would take a moment to bring you up to speed on some of the contaminants making the news in the last month or so.
It is safe to say that this month’s issue has turned into a focus on contaminants. When researching and writing drinking water news for our website, I, of course, get the scoop on both breaking news and some that is less publicized in the greater media. I thought I would take a moment to bring you up to speed on some of the contaminants making the news in the last month or so.

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
