Answer Posted / deepika hemant bankhede
A Quantitative chemical reaction between water and
Anhydrous SO2 and Iodine in the presence of Base(buffer)
that reacts H+.And the amount of water present in the sample is calculated
based on the concentration of iodine in the Karl Fisher
titrating reagent (i.e., titer) and the amount of Karl
Fisher reagent consumed in the titration. and the amount of Karl
Fisher reagent consumed in the titration. Macanism of action- H2O+I2+SO2+CH3OH+3RN=[RNH]SO4CH3+2[RNH]I

My question about gas chromatography sulfur chemiluminsecence detector. I test unknown sample gas by GC-SCD (calibrated ) and the result of *H2S is 279 PPM , *but when I test the same sample with the GC-TCD (calibrated ) the value of *H2S is 2500 PPM . I'd like to inform you that both GCs are calibrated and have very good operation conditions with stable parameters . the question is if the sample gas with higher H2S over detection limits of SCD detector (1000 ppm). why the result it 279 ppm Best regards
