  1. A Modern Approach to Controlling ICP Spray Chamber Temperature Jerry Dulude, Glass Expansion, jdulude@geicp.com

  2. 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 Glass Expansion www.geicp.com 1

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

  4. IsoMist™ Programmable Temperature Spray Chamber Glass Expansion www.geicp.com 1

  5. 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) Glass Expansion www.geicp.com 1

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

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

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

  10. Spike Recoveries in Light NaphthaDirect (no dilution) Glass Expansion www.geicp.com 1

  11. Oxide Reduction in ICP-MSIsobaric oxide interferences Robert Thomas, Practical Guide to ICP-MS, Marcel Dekker, NY, 2004. Glass Expansion www.geicp.com 1

  13. Analysis of Limited Sample Volumes • Biological applications • Intracellular fluids • Neonatal samples • Forensic applications • Requires micro flow nebulization • Low DL’s desirable Glass Expansion www.geicp.com 1

  14. Effect of Temperature on Normalized LOD (20ul/min Uptake) PE Optima 2100DV Glass Expansion www.geicp.com 1

  15. Constant temperature benefits • Environmental monitoring • Tighter CCV’s • Fewer QC’s • Higher productivity • Metal assays • Tighter bracketing • Higher accuracy Glass Expansion www.geicp.com 1
