In HPLC what is Single point threshold, peak purity index
and minimum peak purity index? what should be consider for
pure peak.

Answer Posted / m

Single point threshold is show only peak maxima spectra
whenever peak purity index is shows the front, tail and
peak maxima spectra.

for pure peak we have to consider three point peak purity
which shows that your purity angle should be less than
purity threshold which is clearly shows that your peak is
specrally pure and homogeneous.

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
