In Toc Analyzer Calibration (System suitability) we are preparing Standard sucrose of 500PPb and Benzoquinone Preparing of 500ppb . Sucrose is easy to oxidized and p- Benzoquinone is hard to decompose(oxidized).Its molecule bound not easy to oxidized so the response efficiency defined in USP (united state pharmacopoeia )its response efficiency not less then 85% and not more then 115% . BQ run as control sample in the References of Sucrose .And Its Calculation methods [(rss-rw ) / (rs-rw)]100.
