How do we fix the sample concentaryion in hplc method
development. what is the basis?Thanks in advance
Answer Posted / rajareddy
based on the peak response ,peak height and LOD and LOQ Signal. Ex:sample concentration 1mg/ml than LOQ value (0.1%mg/ml) LOD value(0.03mg/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
