What is suitability test in a Total Organic carbon?
Typically a suitability test is one where the ability of a Total Organic Carbon (TOC) analyzer can recovery a compound with accurate efficiency. Many facilities utilize some quality control standard of a similar matrix to what is being tested for. In most cases, they suitability test is in reference to US Pharmacoepia Method 643, which is the system suitability test (SST) for TOC. In this case a water blank is run followed by sucrose (an easy-to-oxidize solution) and benzoquinone (a more difficult-to-oxidize solution) at 0.5 ppm C. You then subtract each from the water blank and divide the Benz by the sucrose for a recovery that must be within 15%. For more specifics, you can go to www.usp.org to get a copy of the method.
