Introduction Instrument is composed of gas path, light path and circuit of special gas chromatograph flame photometric detector.Sulphide after special chromatographic column separation, in the flame photometric detector signal amplified by photomultiplier tube, then through micro current amplifier amplified signal transmission to the appropriate value and after sulfur concentration is proportional to square of the chromatography workstation dedicated software processing, spectrum peaks can be displayed on the computer with the quantitative analysis of the results.Has bigger difference due to the nature of the sulfide and boiling point, with different columns, specially set up two separate column temperature box.Quantitative sampling tube with a switching valve after switching to a different in the chromatographic column separation. Technical parameters 1.Sensitivity: Mt 5 x 10-12 g/s or less (COS), COS. CS2, H2S: : minimum detectable concentration is 0.03 PPM SO2: minimum detectable concentration: 0.2 PPM 2. Oven temperature, column 1 room temperature + 5 ℃ ~ 150 ℃, accuracy of plus or minus 0.2 ℃. Column 2 room temperature + 5 ℃ ~ 100 ℃, accuracy of plus or minus 0.2 ℃. 3. The baseline drift ≦ 0.1 mv/h Features 1. The analysis speed, short analysis period, analysis of CS2 is about 3.22 "; H2S is about 3.08 ". 2. High efficiency of separation: through long-term repeated test, choose out of the two special chromatographic column. 3. The start time is short: about half an hour can be put into use. 4. Stable and reliable operation and convenient. 5. The instrument has analog signal and digital signal transmission, the user can be put into use computer on.
