Why we have to do system suitability test to TOC…?
System suitability is done to make sure if the instrument is sensitive in desired limit. .
TOC system suitabilty test is esigned in such a way that, you to at least 2 materials, i which one is readily oxidizable (sucrose) and the second one is very difficult to oxidized (1-4 benzoquinone). so if your system oxidize, easily oxidizable and difficult to oxidize material, then your system is suitable for testing of TOC.
