Glass Expansion - Helix CT ICP Spray Chamber

• Potential for contamination due to dead volume around the o-ring seal
• Chemical resistivity of strong acids and organic solvents
• The o-rings are difficult to replace, often requiring tools
• Bonding to the nebulizer can result in breakage

Glass Expansion is now pleased to introduce the new Helix CT spray chamber with ConstantTorque technology, which provides a constant, reproducible, inert, gas-tight seal between the nebulizer and spray chamber.

The main feature of the Helix CT spray chamber is a new Helix locking screw with a built-in torque control mechanism that allows for a consistent seal of the PTFE ferrule against the nebulizer –making it impossible to overtighten or under tighten while ensuring a gas-tight seal every time. A new PressFit PTFE ferrule provides a chemically inert seal around the nebulizer, which is immune to strong acids and organic solvents routinely used in ICP sample preparation. The new Helix CT cyclonic spray chamber by Glass Expansion, therefore, eliminates all the drawbacks of the o-ring nebulizer seal, while improving user safety by preventing broken nebulizers.

The new Helix CT nebulizer interface is also simple to use:

• Fully insert the nebulizer into the Helix CT interface, until the nebulizer side-arm comes into contact with the molded-in positive stop.
• Hand-tighten the Helix CT locking screw until the ConstantTorque mechanism clicks, indicating a secure, gas-tight seal.
