we are performed SOR for a particular product the limit is -6 to -10.We face particular bathes it is not meeting the specification.we performed diffrent instrument diffrent analyst we are getting diffrent diffrent results.solvent is dimethyl sulfoxide what could be the reasion
why we are using hexane in calibration of number of drop per mL

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
