pH Play the role for ionisation and unionisation of drug molucule in mobile phase..if our drug moity is acidic nature and our mobile phase pH is acidic then our drug moity behave to unionised and unionised molecule behave like hydrophobic or nonpolar so drug moiety more attract to stationary phase( coloum) so it not eluted with mobile phase readily and mor time expend in coloum.

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
