QC for Water Treatment Chemicals

We have a new capability that we are offering to our water treatment clients, quality control of water treatment chemicals according to AWWA and ANSI/NSF 60 standards. These chemicals should be tested to insure that they are correctly identified, that they have the proper strength, and that they do not contain unwanted impurities.

Our lab has developed these capabilities based on (1) a request from the City of San Francisco, for whom we are now an approved vendor, and (2) the other monograph and compedial testing we have been performing for the pharmaceutical and chemical firms for many years (USP/NF, ACS, EP, JP, etc.).

These are examples of chemicals and tests that we offer. If you don’t see the test or chemical that you require, we may still be able provide the service. We are constantly adding new tests. Even if the chemical is not in any monograph, we can contact the supplier and find out how they QC their product or develop tests independently.
