Presentation Transcript

  1. Thermal stabilization of spray chamber improves long-term stability Reduces effect of laboratory temperature variation on signal stability Reduces solvent loading. Fast rinse-out using PFA-ST nebulizer and O-ring-free quartz cyclonic spray chamber. Reduced oxides Enhances stability with PC3-SSI Chamber: Isotope ratio measurements Other analyses requiring improved precision Additional reduction of oxides vs. standard PC3 Optional oxygen addition port for organic solvents. PC3 Advantages

  2. Default settings of spray chamber temperature (+2 C/ -5 C) for aqueous or organic solvents. Custom temperature settings available upon request. Quartz cyclonic or HF resistant cyclonic spray chambers available. Direct connection to torch injector. Completely o-ring-free for organic solvents analysis. Organic solvent analysis using PFA-50 nebulizer. Aqueous sample analysis using PFA-ST nebulizer. PC3-SSI model for isotope ratio determination or other high precision analyses. Optional mounting tray for x-y-z torch adjustment. Air-cooled. PC3 Features
