Indicating Oxygen Traps chemically convert oxygen in carrier gas streams and uses a high capacity oxygen adsorbent and an indicating adsorbent to display depletion.

Adsorbs up to 40cc's of oxygen to less than 30ppb levels	Approx. dimensions: 3.2 x 26cm
Inner heavy walled glass tube encased in a hard plastic tube for      added safety and strength
Redundant three part inner seal for leak-free operation
Can be regenerated - no need to dispose

The Model 1000 high capacity oxygen trap  is specifically designed for the bulk removal of oxygen for capillary use, especially with ECD and GC-MS systems.

NOTE:  The active catalyst in this high capacity oxygen trap becomes hot when exposed to air.  According, this Trap MUST ship as HAZARDOUS GOODS.

Over 2.5 liter O2 capacity from 500cc's of adsorbent	Approx. dimensions: 5 x 37cm
Removes O2 to less than 70ppb oxygen levels at the outlet
Nickel plated steel construction rated to 1000psig
Maximum flow of 1L/min recommended
Can be regenerated (instructions are included)
Delivered filled with high purity helium - ready for use

We recommend using the Indicating Oxygen Trap (at top) downstream from this Model 1000 trap to show when its capacity is depleted.

For use with ECD or ElCD detectors where high purity gases are required.
 

Molecular Sieve 5A and Indicating Drierite® adsorbing materials	Approx. dimensions: 3.2 x 26cm
Inner glass tube encased in plastic shell with threaded aluminum      end caps - makes it easy to disassemble and reactivate
Stainless steel frits with nickel plated end fittings
For use below 100psig

Improves baseline stability and chromatographic data by trapping moisture, oil, and dust before it reaches your GC.  Recommended for the filtration of hydrogen in FID's.

400cc capacity - requires fewer refills	Approx. dimensions: 6 x 43cm
Replaceable molecular sieve and indicator
Drierite® changes from blue to pink at 5% relative humidity to      warn of leaks in the gas stream.
Simple construction allowing for easy disassembly
Clear acrylic tube rated to 100 psig

The Model 300 Hydrocarbon Trap removes hydrocarbons from hydrogen and other gases.  It contains 500cc's of pure activated charcoal - more than twice the capacity of other leading hydrocarbon filters -removing all hydrocarbons except methane at room temperature.  The all-metal cylinder rated to 1000psig.

500cc capacity	Approx. dimensions: 5 x 37cm
Highest efficiency is obtained using flow rates below 500 cc/min.
Frits in each end prevent fines from entering the gas stream.
Can be regenerated

During split injection mode, more than 99% of your sample is vented to the atmosphere.  The Split Vent Trap contains 1200 milligrams of pure activated charcoal which captures these volatile contaminants venting from split/splitless injectors.  The Split Vent Trap consists of the inner glass adsorbent tube with nickel plated end fittings, clear plastic protective outer sleeve and 1/8" tube fittings.  Each trap comes with three replacement tubes.

High capacity - 1200mg of activated charcoal
Protect your health and the health of your coworkers
Three replacement cartridges included
