what is the need of calulation of RRF of impurity in HPLC
analysis?
Answer Posted / laura
Hi,
When a different marker is used to find out which impurity is seen in the chromatogram due to not being availble, and a really similar compound is used (in this case the salt ) how can I calculate the RRF of the compound which was not available in regard to the one that was tested? I calculated the RRF of the compound tested, but how can I extrapolate to the one I am looking for?
Many thanks in advance,

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
