Agilent Big Universal Trap, 1/8inch fttgs,Helium RMSH-2

The Agilent Big Universal Trap (RMSH-2) is an inline gas purifier specifically produced for carrier gas purification (helium) in GC and GC–MS systems. It houses a combination of adsorbents in a single large-capacity body to remove oxygen, moisture and hydrocarbons, simplify installation, and reduce potential leak points compared with multiple smaller traps. The unit is supplied with 1/8‑inch fittings and is intended to provide research‑grade effluent purity and reliable protection for columns and detectors.

Key Features:

• Fitting size: 1/8 in.
• Body material: Brass.
• Overall length: 17.5 in.
• Maximum pressure rating: 300 psig (per Agilent product listing).
• Trap capacity: 750 cc (adsorbent volume).

Advantages:

• Removes O2, H2O and hydrocarbons to improve carrier gas purity and protect detectors and columns, supporting GC/MS applications.
• Large single-unit capacity reduces frequency of replacement and consolidates three trap functions into one, lowering leak points and simplifying installation.
• Designed for common lab pressures and flows (high pressure rating and up to ~8 L/min flow in installation guidance), enabling robust operation in typical GC setups.
