Helix CTTM ICP Spray Chamber
with ConstantTorque Technology
Provides Consistent Day-to-Day
Analytical Performance
Abstract
Glass Expansion revolutionized spray chamber design for the ICP-OES and ICP-MS
analyst by introducing cyclonic spray chambers. Prior to the Glass Expansion TraceyTM
cyclonic spray chamber, Scott-style spray chambers were the standard option provided
with your ICP. The design of Glass Expansion’s cyclonic spray chambers helps the ICP
analyst achieve sensitivity gains, reduced washout times, and reduced matrix effects
not possible with other designs.
This article will provide a summary of Glass Expansion’s unique cyclonic spray chamber
features and describe the advantages of the new Helix CTTM ICP spray chamber with
ConstantTorqueTM technology.
Introduction
Traditionally, ICP-OES and ICP-MS sample introduction systems have relied on o-rings
to form a gas-tight seal between the nebulizer and spray chamber. There are several
drawbacks with an o-ring seal, such as:
• 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
The evolution of Glass Expansion cyclonic spray design, specifically the advantages
of the Helix nebulizer-spray chamber interface were summarized in a 2014 article.1
In addition to the Helix interface, the benefits of each Glass Expansion cyclonic spray
chamber model are detailed1 making it easy for the ICP analyst to select the optimum
spray chamber to suit their application needs. Glass Expansion is now pleased to
introduce the new Helix CT (ConstantTorque) spray chamber, which provides a
constant, reproducible, inert, gas-tight seal between the nebulizer and spray chamber
(TwisterTM with Helix CT shown in Figure 1 on page 2).
