9.3.6.1 PermaPure Drier

The PermaPure drier is constructed of 2 concentric tubes. The inner tube is a special material that has an affinity for water vapor. The outer annulus is evacuated by the instrument pump. This creates a concentration gradient causing water in ambient air to diffuse into the outer annulus, thus the air in the inner tube becomes progressively drier as it progresses down the tube.

Due to the large number of connections and fittings on the drier, the most common drier fault is leaks. Before proceding with any other procedures check the drier for leaks.

Occasionally the drier gets contaminated. The manufacturer of the drier recommends replacing the drier rather than trying to clean it. If cleaning is chosen, the following options are available:

1.Dirt - Clean any solids from dryer inlet by brushing. Use clean dry air to blow any loose particles from the inlet. Deionized water or dilute(5-10% conc HCl in deionized water) hydrochloric acid can be passed through the dryer. This should be done only with the dryer and HCl at room temperature.

2.Organic liquids and freons - Rinse the inner and outer tubes using 1,1,1 trichlorethane. Follow the solvent with dry air to purge the solvent.

3.Inorganic salts and oxgenated hydrocarbons can be removed by rinsing with 10% nitric acid at 50° C.
