A Nebulizer Update
In June of 2008, Glass Expansion released a Newsletter article addressing ICP Nebulizer
Selection and Maintenance. Since that time our line of nebulizers has expanded and
designs have improved to better support the demands of the ICP-OES and ICP-MS
analyst. This article will provide a summary of these additions and design changes, as
well as addressing proper nebulizer maintenance and presenting an updated guide to
nebulizer selection.
What Makes a Glass Expansion Nebulizer Unique?
Glass Expansion is most notably known for the unique VitriCone™ sample channel
of the glass concentric line of nebulizers (MicroMist, SeaSpray, Conikal, and Slurry).
The VitriCone sample channel is created by machining constant bore heavy stock
glass tubing to create the desired aerodynamic exterior while maintaining a consistent
internal diameter. Other manufacturers heat and draw a thin fragile capillary from glass
tubing to create the internal capillary. This process is prone to a number of potential
problems including inconsistent inner diameter, an increase in the porosity of the glass,
and harmonic vibrations from the flow of argon, all of which degrade performance and
lifetime. A diagram comparing a Glass Expansion nebulizer (A) to other brands (B) is
shown in Figure 1.
59th ICASS

Figure 1: Glass Expansion VitriCone construction versus other brand glass concentric nebulizer.
The benefits of the VitriCone construction are:
• The sample channel is guaranteed uniform and thus resistant to clogging.
• The rugged precision-machined capillary resists vibration and delivers the best
possible precision.
• The industry’s tightest tolerances ensure that each nebulizer will perform to the same
high standards as the previous one.
