The experiment in this thesis determines the S and C in geological samples by HF - IRCS Analyzer , based on the selective absorption of CO2 and SO2. The precision based on national’s CRM(certified reference material). The RSD% of C ranges from 2.47% to 8.5%, and the RSD% of S ranges from 2.95% to 3.9%. The precision also based on national’s CRM(certified reference material). The RE% of C ranges from -3.33% to 1.78%, and the RE% of S ranges from -2.4% to 4.1%.The limit of detecton of C is 0.5709%, and S is 0.0103%. Using HF - IRCS Analyzer, the stability of sampled-data is good, and a low detection limit is maintained.
