1 A Modern Approach to Controlling ICP Spray Chamber Temperature Jerry Dulude, Glass Expansion,

2 Glass Expansion 1 Limitations of Externally Controlled Spray Chambers Requires antifreeze solution Requires bulky floor model chiller Cumbersome coolant lines from chiller to chamber Freezing of condensate on lines Requires intricate jacketed chamber

3 Glass Expansion 1 Limitations of other Peltier Controlled Spray Chambers Lack of programmability Insufficient cooling Require external fluid supply Limited temperature range Limited compatibility

4 Glass Expansion 1 IsoMist™ Programmable Temperature Spray Chamber

5 Glass Expansion 1 Features of IsoMist Powerful Peltier-effect chiller reaches -5C in 15 minutes Programmable from -10 to 60C in 1 degree increments Maintains temperature to within 0.1 degree Compact design (7.5x4x4 inches) 100% self-contained (no external lines) Incorporates Bluetooth® technology for clean wireless control (USB available)

7 Glass Expansion 1 Variety of Cyclonic Spray Chambers Borosilicate glass: most aqueous and organic applications Quartz: Trace boron determinations PFA: HF and ultra trace applications

8 Glass Expansion 1 Applications of the IsoMist Analyze volatile solvents – Low temp. Reduce oxide interferences – Low temp. Lower detection limits – High temp. Increase stability – Constant temp.

9 Glass Expansion 1 Determination of Trace Metals in Naphtha Interfere with the cracking process Poisoning of the catalysts Environmental release concerns Origin and migration markers

10 Glass Expansion 1 Spike Recoveries in Light Naphtha Direct (no dilution)
