Answer / dinesh solanki
If it is a assay method then inject std in hplc system and compare the chromatogram and identified the interested peak from them.
Same RC method inject std and identified the interested peak and other is may be impurities or contamination of sample.

what is difference between Performance check and Calibration?
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
