This explosion-proof chromatograph is designed for on-line automatic measurement of the mass concentration of sulfur-containing compounds in combustible natural gas (CNG) in accordance with ASTM D 7493, ISO 19739 with subsequent calculation of the total and mercaptan sulfur content.
- Selective ECD detector;
- Carrier gas - compressed air;
- Detection limit - from 0.01 ppm (H2S);
- Hydrocarbons do not affect the analysis;
- Linear characteristic: calibration by 1 CGM;
- Wide measurement range.
Measurement ranges and the values of the relative expanded uncertainty of the measurement result of the mass concentration of sulfur-containing components in the analyzed sample correspond to ASTM D 7493.
Option: can be manufactured in a laboratory based design.
