TRS Total Reduced Sulfur ,Model 101E/102E

H2S & TRS Analyzers for Ambient Air Quality Monitoring

The Models 101E/102E provide a dependable, accurate and convenient method of measuring hydrogen sulfide or Total Reduced Sulfur (TRS) in levels commonly required for Ambient Air monitoring, offering ranges from
0-50 ppb to 0-10 ppm. Both analyzers convert sulfur gases to sulfur dioxide and measure concentrations using fluorescence technology.

The M101E is equipped with an internally mounted low temperature converter which converts H₂S at a closely controlled temperature setting of 315 °C, leaving other gases unaffected. The M102E uses a high temperature
converter, mounted externally to the analyzer, and operates at a temperature of 850°C. TRS components (typically, H₂S, methyl mercaptan, dimethyldisulfide and methyl-disulfide) are all converted to SO₂ at this temperature, with efficiency greater than 98%.

Sample gas drawn into the analyzer first passes through a scrubber which removes all traces of sulfur dioxide. The converter then converts the components of interest to SO₂. The resulting concentration for SO₂ is then measured by fluorescence. In the basic configuration, the analyzer may be programmed to read H₂S concentration (101E) or TRS (102E) only. However, a switching option, showing H₂S/TRS and SO₂ readings alternately, is available. Cycle times may be adjusted, and each reading is truly independent, having its own calibration slope and offset. A sample and hold circuit provides continual analog outputs for each channel. Calibration is simplified by the optional zero and span valves, which allow direct entry of calibration gases, or the optional permeation tube may be used to provide span checks. The analyzers feature auto zero which
provides excellent zero stability.
