How you will select the runtime in HPLC for a drug in
method development.
Answer Posted / rahul
There are two three concerns to keep in mind when setting a
run time during method development.
1)Refer the degradation study data of the product.due to
this you come to know about the product beheviour with
method during stress conditions.
2)Confirm the impurity and main compund mass balance test
because of this you will assure about no further elution.
3)Run the HPLC for 5X to the column volume due to this you
can assure about and late elutions.
If with these experiments there is no elution after certain
time you can set the run time after 5 to 10mins after last
peak elution.

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
