Why sulpuric acid only used to ROI but not used nitric acid
and some other acids?
Answer Posted / amarendra allu
sulpuric acid is strong acid and after addition of H2SO4 ORGANIC COMPOUND WILL DECOMPOSED AND VAPORISED BY IGNITING. ROI IS CONTENT OF INORGANIC ,after addition of H2SO4 to compound it converting into their sulphates with the treatment of H2SO4 and sulphates are very stable at high temperature
(about up to 800-1000). while nitrates and chlorides are
not stable at high temperature.

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
