Moisture Control and Gas Conditioning for Reliable Measurements

Precise drying and humidification solutions for industrial, environmental, and medical gas analysis

In gas analysis, moisture is often the hidden variable that distorts readings, corrodes instruments, and increases maintenance needs.

Perma Pure, a Halma company, provides advanced gas conditioning and moisture control technologies that solve this problem — delivering dry, clean, and stable samples for accurate measurement and dependable system performance.

Technology Built on Nafion™

Perma Pure’s unique advantage lies in its use of Nafion™ polymer, a fluorocarbon ion-exchange membrane that selectively transfers water vapor while leaving analyte gases unaffected. This technology allows Perma Pure’s dryers and humidifiers to:

Remove excess moisture without sample dilution or chemical interference
Maintain precise gas composition for accurate analysis
Resist chemical attack and corrosion even in harsh environments

These properties make Nafion™-based systems ideal for continuous emissions monitoring (CEMS), biogas process control, combustion analysis, and laboratory applications.

Complete Gas Conditioning Systems

For process and emissions monitoring, Perma Pure designs integrated gas sample conditioning systems combining dryers, coalescers, filters, and heated sample lines.

These systems convert hot, wet, contaminated gas samples into the clean, dry samples required by analytical instruments — ensuring compliance with environmental standards and reducing analyzer downtime.

Humidifiers and Specialty Components

In medical and life-science applications, Perma Pure humidifiers add controlled moisture to breathing air or medical gases, protecting patients and ensuring reliable test results.

Specialty scrubbers and filters also address CO₂, NH₃, or acid gas removal, enhancing system lifetime and precision.
