The CETAC Aridus II™ Desolvating Nebulizer System is a specialized accessory for all types of ICP-MS instruments. Particular benefits and features of the Aridus II™ include:

• Sensitivity enhanced up to 10x or greater for ICP-MS
• Patented PTFE membrane desolvator for extremely low oxide (CeO/Ce < 0.03%) and hydride levels
• Modular design of membrane desolvator for easy removal and cleaning
• Covered PFA spray chamber for reduction of electrostatic effects
• Improved signal stability, even for organic solvents such as methanol
• Equipped with the tunable Aspire PFA Nebulizer, with flow rates of 50, 100, and 200 µL/min

The figure to the right shows long term Aridus II™ stability data for a 1 µg/L spike into 100% methanol. For a 7-hour run the Aridus II demonstrates exceptional signal stability, with %RSDs at or less than 1%.

Additional performance data using the Aridus II™ with qudrupole and multicollector ICP-MS is given in the literature links at the left side of this page.
