6 views 1
Most popular method used by Perma Pure customers by unit volume
The split sample method is similar to the Reflux Method previously described except that it channels a portion of the sample gas through the Nafion tubing serving as the purge gas before the analyzer.
Choose the split sample method if it is not possible or practical to route the analyzer exhaust back to the gas dryer.
The dryer must be up-sized for the increased flow rate adding the portion used for the purge gas to the sample gas flow rate required for the analyzer.
Additionally, the right purge gas amount will need to be selected to provide optimum drying performance.
Provides a consistent dryness level at the output when run continuously.
