Conclusions
The results from our study show how dead volume around the
nebulizer seal can affect washout efficiency, and ICP sensitivity is
affected by both nebulizer depth within the spray chamber and the
torque applied to the nebulizer seal. If consistent performance is
crucial to your ICP laboratory, the new Helix CT spray chamber is
your solution. The Helix CT spray chamber provides unparalleled,
reproducible day-to-day ICP analytical performance.
Glass Expansion will now equip all of its glass, PFA, and PTFE spray
chambers with the new Helix CT interface. However, if you already
have a Helix spray chamber, you can easily upgrade to the Helix
CT interface. The new Helix CT locking screw and PressFit PTFE
ferrule are fully compatible with all Glass Expansion Helix style spray
chambers. Achieving consistent day-to-day analytical performance
in your ICP laboratory is just a click away with the new Helix CT
cyclonic spray chamber, learn more at www.geicp.com/HelixCT and
upgrade your ICP today.
