Peltier Based Sample Handling System
The Uniphos Peltier Cooled Probe is an advanced sample conditioning system to draw a gas sample from an emissions stack being monitored. Sample extraction and conditioning is an important part of all Continuous Emission Monitoring Systems (CEMS) and includes extracting the sample from the stack and maintaining the dew point of the sample at such a level that there is no condensation at any point until the concentration of the sample is measured. This ensures proper transport and measurement of sample concentrations.
The Peltier Cooled Probe is a unique product which is based on an advanced hot and dry extractive technique where the sample is extracted and conditioned on the stack and transported to the analyzer using a non-heated sampling tube at ambient temperature. It consists of a stack mountable system which includes a heated probe, a short, heated sampling line and a Peltier cooled sample conditioning module, all integrated in a single enclosure. Using a Peltier Cooled Probe reduces the length of the heated sampling line to less than half a meter, bringing down the operating cost many times.
