GC-HS is useful for Residual solvents. since the sample is
heated about 40 minutes. then the volatiles present in the
sample will come to the empty space(Head space)of the vial.
then the needle will suck the vapour and inject into GC. It
means we are extracting the volatiles from the material
before injection.
In case of GC- Direct injection, sample also will go into
GC.

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
