Why do we use 500ppb sucrose and 500ppb 1,4 benzoquinone in TOC calibration?..

Answer / vishal shah

In TOC calibration 1,4 Benzoquinone used because 1,4
Benzoquinone is tufest to oxidized and sucrose is easly
oxidized so cover upper and lower range for calibration.

Why do we use 500ppb sucrose and 500ppb 1,4 benzoquinone in TOC calibration?..

Answer / dev rawat

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.

Why do we use 500ppb sucrose and 500ppb 1,4 benzoquinone in TOC calibration?..

Answer / amarjeet kumar

Any sample in TOC analyzer is being purged with inert gas aftrr mixed with an acid and 1,4 benzoquinone is the toughest as said above to get oxidised others may get easily oxidised.

Why do we use 500ppb sucrose and 500ppb 1,4 benzoquinone in TOC calibration?..

Answer / dignesh udwadia

sucrose is high oxidation and 1,4-benzoquinone is vary low oxidation to cover higher and lower oxidation range we are used above mention material for calibration.

Is This Answer Correct ?    7 Yes 1 No

Why do we use 500ppb sucrose and 500ppb 1,4 benzoquinone in TOC calibration?..

Answer / umamahesh

sucrose is high oxidation and 1.4- benzoquene is very low oxidation to cover higher and lower range
