In order to measure TRS in accordance with the federal regulations, the sample must be measured on a dry basis and be corrected to a fixed Oxygen (O2) content. This is accomplished by extracting the sample from the process using the Thermo Scientific PRO902C Low-Flow Dilution Probe.
First, the sample is passed through a water removal device to provide a dry sample. The oxygen content is measured and the sample is diluted to an appropriate level, depending on the site conditions.
The diluted sample is sent through a sample line to the instrument cabinet and passes through a selective scrubber where Sulfur Dioxide (SO2) is removed and TRS is allowed to pass. Next, the sample is routed to a thermal oxidizer where the TRS compounds react with O2 under high temperature, and is then sent on to the 43iQ SO2 analyzer..
Key Features:
- Designed to meet U.S. EPA 40 CFR Part 60 requirements
- Dry-basis measurement
- Reliable pulsed-fluorescence technology
- Corrective oxygen measurement
