The PUR-Gas™ Inline Purifier System offers a traditional “in-line” (trap) configuration for point-of-use gas purification in laboratory environments. This versatile system easily integrates into existing gas delivery lines or can be wall-mounted using clips for space-saving installation. The unique “End Connectors” enable tool-free replacement of purifiers within seconds. Integrated check valves automatically seal the gas lines during purifier replacement, preventing atmospheric contamination and preserving gas purity. Like the PUR-Gas™ Cartridge Purifier System, this inline system delivers 99.9999% gas purity through effective contaminant removal.

Applications

• Point-of-use purification of all gases utilized with the operation of an FID equipped GC.
• Ideal for purification of carrier gases used with GC/MS, ECD, PID and NPD detectors.
• Removal of hydrocarbons (n-butane (C₄H₁₀) or heavier) and moisture from FID fuel gases.
• Purification of Nitrogen for LC/MS instruments.

Design Features

• Quick-connect “End Connectors” enable tool-free purifier replacement.
• Replacement purifiers can be installed within seconds, minimizing instrument downtime.
• Integrated check valves in the “End Connectors” prevent contaminants from entering gas delivery lines during replacement.
• Single purifier design enables removal of hydrocarbons (n-butane (C₄H₁₀) or heavier), oxygen, and moisture.
• Visual “End Point” Indicator available for Moisture and Oxygen breakthrough optimizes purifier performance and signal when replacement is needed.
