1 Elemental Scientific | | PC 3 Advantages 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.

2 Elemental Scientific | | PC 3 Features 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.
