Scrubber with Selectable Media

The Universal Analyzers Scrubber is designed to hold a variety of medias to remove non-analyte components that can negatively impact a sample conditioning system or analyzer. A common media will remove Ammonia from a gas stream to protect the analyzer from interference due to the formation of salts. Ammonia when present in gas samples, will readily react with other components such as Sulfur Dioxide in the sample to form ammonium salts. This salt is relatively low-boiling, so it is present as a gas at the higher temperatures in the stack and in the heated line. When the sample cools, it precipitates out as a solid, clogging or impairing the chiller or analyzer.
