GAS PURIFIER
This DRIERITE Gas Purifier is specially designed for gas chromatography and other applications requiring dry, pure gas.
It will dry, purify, and filter gases used for chromatography and spectrometry. The purifier is filled with Indicating DRIERITE
and Molecular Sieves for the removal of moisture, impurities, and particulates from gas lines. It is easy to attach using
the compression type tube fittings common to most laboratory instruments. This unit is available filled with 500 cc
of Indicating DRIERITE for applications that require only drying and filtering. Plastic coated mounting clips may be
purchased separately.
Note: Do not use this drier in the presence of vapors or liquids containing phosphate esters, synthetic lubricants,
hydrocarbon solvents, methanol, acetone, lacquer solvents, or other organics. | Color Change
Indicating DRIERITE dries gases to a dryness of 0.005 mg/l. Color changes from blue to pink upon exhaustion. | Molecular Sieves
Molecular Sieves remove impurities that have an effective molecular diameter of less than 5 angstroms. | Applications
For use in gas chromatography to prevent ghost peaks and to improve baselines. The gas purifier should be used
for carrier gases and for flame lonization detector air and hydrogen gases. The gas purifier may also be used to
remove moisture and impurities from gases when purging spectrophotometer compartments, etc. | Refillable
Refillable upon exhaustion （DRIERITE turns pink） with refill kit Stock No. 27069, or contents may be regenerated.
