what is the principle involved in determination of moisture
content?

Answer Posted / archana

The sample is dissolved in a solvent which is content in a
moisture free vessel & titrated against the KF sol. the
unknowm water content of sample is determined by measuring the
volume of KF sol.required to reach the end pt. of titratn.
simply..
water content = consumption of kf soln.in ml x titrated value
of KF soln.

titrated value = mg of water/ml of KF soln.

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
