Description:
A prototype Source Analyzer has been tested during a Phase I SBIR contract. Its function is to monitor stacks and process streams and exercise computer feedback control to optimize combustion or other processes and to minimize pollution. The analyzer employs Gas Filter Correlation (GFC) Photometry to measure gases in the PPM range. Probe extractive sampling is used, and the unit is compact, potentially portable and intended to be cost effective to reach a large market. A stepper motor controlled multigas gas filter correlation wheel is used to discriminate each of the gases to be measured. NO,, N,O, SO,., HCI, HC's and CO have been successfully measured. Other gases, notably NO, should become analyzable with the substitution of a longer range IR detector than the one used in the study (lead selenide). The system, including the GFC Photometric Analyzer Module, is controlled by an IBM PC, and with the exception of the Photometer Module, can be assembled by the user from off-the-shelf components including commer- cially available control softwear. The innovative aspects employed in the GFC Photometer include true hermetically sealed gas cuvettes (no cemented windows) and the potential extended spectral range of operation from the UV to the mid-IR. The compact photometer, hand carried, can be controlled by a laptop computer, and would be affordable and operable by small companies and municipalities.Supplemental Keywords:
