Glass Expansion News June 2013

NEWS Glass Expansion Newsletter | June 2013 | Issue 31 GE NEWS Application Spotlig ht 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 Glass Expansion will be exhibiting at the 59th ICASS (International Conference on Analytical Sciences and Spectroscopy) which is being held in conjunction with Spectr’Atom 2013 on June 25 to 28 at Mont-Tremblant, Quebec, Canada. NYAAEL/PaAAEL 2013 Annual Convention & Exposition The NY Association of Approved Environmental Laboratories (NYAAEL) and the PA Association of Accredited Environmental Laboratories (PaAAEL) will hold their 2013 Annual Convention and Exposition at Gettysburg, PA, USA on July 21 to 23. This year’s meeting will have a focus on Automating Manual Techniques and Glass Expansion products will be on display. JASIS 2013 A full range of Glass Expansion products will be on display at JASIS 2013, Tokyo, Japan, September 4 to 6 and Glass Expansion specialists will be on hand to assist you.

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. www.geicp.com page 1
