The entire sample stream, from the probe stinger to the analysis bench, is maintained at a temperature of 190 °C to prevent sample loss or condensation. The Omni FTIR Multi Gas CEMS has the unique ability to switch to a Flowback mode that purges the sample stream all the way from the analyzer through the sample line to the tip of the probe.
