Answer Posted / king_suresh-chelika
Peak purity concept is spectrally homogeneity of a perticular peak, if two or more peaks having same polarity, then they will come at same RT (most probably some times merge with each other)
Even though they have different uv absorption, due to same polarity, peaks merged or co elution observed.
In this case, angle will be higher than threshold,results peak purity fails

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
