Process and apparatus for simultaneous measurement of sulfur and non-sulfur containing compounds |
| abstract |
The present invention describes the process and apparatus for the simultaneous measurement of sulfur-containing compounds and organic compounds with or without sulfur in their structures. A detector cell is described that allows simultaneous measurement of compounds that can be ionized in a flame and thereby cause the electrical conductivity of the flame to increase, and the selective measurement of sulfur-containing compounds which simultaneously form sulfur monoxide. Sulfur monoxide, upon mixing with ozone, emits light from 240 to 450 nm. The intensity of the light can be measured and related to the concentration of sulfur in the sample, while changes in electrical conductivity of the flame measured by imposing a voltage across the cell quantifies the organic compounds irrespective of whether or not they contain sulfur. Ratios of the signals of light intensity and electrical conductivity are different for each compound and, when the detector is coupled with a chromatographic separation column and process, this ratio facilitates the identification of unknown constituents in a mixture. |
