The Agilent Big Universal Trap (RMSH-4) is a high-capacity in-line gas purifier intended for helium carrier gas used in GC and GC‑MS systems. It combines layered adsorbents to remove oxygen, moisture, hydrocarbons and other common contaminants, protecting columns and MS detectors, reducing stabilization time and simplifying installation using 1/4‑inch fittings.

Key Features:

  • Fitting size: 1/4 in (Swagelok-style fittings as shipped).
  • Intended gas: Helium (designed for GC/MS carrier gas purification).
  • Trap packing capacity: 750 cc (big universal trap packing volume).
  • Length: 17.5 in; outer diameter ~2.3 in (unit dimensions as listed).
  • Maximum flow rate: up to 8 L/min (manufacturer performance spec for treatment).
  • Maximum temperature rating: 100 °C (operating temperature limit stated by manufacturer).

Advantages:

  • Much larger single‑unit capacity than standard in-line traps (reduces frequency of replacements).
  • Combines the function of multiple traps into one unit, lowering the number of fittings and potential leak points.
  • Removes O2, H2O, hydrocarbons and CO/CO2 to improve detector sensitivity and protect GC columns and MS inlets.
  • Speeds system stabilization and simplifies installation and replacement for routine GC/GC‑MS maintenance.
