Gas Traps
22081
High-Capacity Indicating Oxygen Trap
• Indicator changes from dark blue to black as oxygen & water
are trapped.
• Lasts longer than three smaller traps.
• Use with all carrier gases.
• Ambient operating temperature, 100 psi (689 kPa) operating
pressure.
• Built-in frit traps microparticles.
• Outlet gas purity:
O
2
< 0.1 ppm when inlet does not exceed 15 ppm.
H
2
O < 0.5 ppm when inlet does not exceed 10 ppm.
• Maximum operating pressure: 150 psi (1,034 kPa).
• Maximum flow: 16.5 L/min.
Dimensions: 9

Indicating Oxygen Trap
• Indicator changes from light green to grey as oxygen is
trapped.
• Heavy-walled glass body, protected by polycarbonate sleeve,
prevents oxygen & water infusion.
• Prepurged for fast stabilization.
• 100 psi (689 kPa) maximum operating pressure.
• Reduces oxygen to 0.1 ppm.
• 10 µm frits at inlet and outlet.
Dimensions: 10" x 1

High-Capacity Oxygen Trap
• Removes up to 600 mg of oxygen or 2 g of water.
• Long life—typically purifies more than five 200 ft
3
cylinders.
• Reduces oxygen to 15 ppb.
• Maximum operating pressure: 250 psi (1,724 kPa).
• Flow: 3 L/min. @ 32 psi (221 kPa).

Rechargeable Molecular Sieve S-Trap
• Traps water vapor; increases
column and oxygen trap lifetime.
• Reduces baseline noise from
sensitive detectors such as ECDs
and mass spectrometers.
• Activated and ready to use.
• Reduces water to less than 1 ppm.
• Fits in GC oven for easy thermal
recharging.
• Maximum flow: 1 L/min.

High-Capacity Moisture Trap
• Purged with ultra-high-purity helium; ready to use.
• Reduces water to less than 15 ppb.
• Maximum operating pressure: 250 psi (1,724 kPa).
• Maximum flow: 1.25 L/min.

Indicating Moisture Trap
• Reduces water to less than 10 ppb; indicator changes from
orange to green at 5% relative humidity.
• Prepurged for fast stabilization.
• Reduces noise from high-sensitivity detectors.
• Heavy-walled glass body prevents oxygen & water infusion.
• 10 µm frit prevents microparticulate damage to needle valves
and flow controllers.
• Maximum operating pressure: 100 psi (689 kPa).
Dimensions: 13" x 2" (33 x 5.1 cm)
