Aridus3 Desolvating Nebulizer System by Teledyne CETAC

The Aridus3 Desolvating Nebulizer System is a specialized sample introduction accessory for Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

The Aridus3 can enhance analyte sensitivity up to 10 times and can greatly reduce solvent-based interferences such as oxides and hydrides. The Aridus3 couples the C-flow PFA nebulizer and a heated PFA spray chamber with a PTFE membrane desolvator unit. This combination provides enhanced analyte sensitivity while reducing solvent based interferences, such as oxides and hydrides. The Aridus3 is particularly advantageous for small volume and highly corrosive samples (e.g. HF) such as those generated in the earth sciences and the semiconductor industry.

The Aridus3; can be easily interfaced with all current t ypes of ICP-MS instruments, including quadrupole, high-resolution (HR), multi-collector (MC) and time of flight (TOF) systems. The sample path (nebulizer, spray chamber and membrane), are all made of inert fluoropolymers which are resistant to all acids including hydrofluoric acid (HF). Sample-solvent vapors pass through the inert membrane to vent, providing very low oxides (%CeO/Ce is usually 0.05% or less).

Key Features:

• Sensitivity enhanced by a factor of 4 to 10 times
• Low volume sample uptake rates of 50, 100 or 200 μL/min
• Unique, tunable Aspire™ PFA Nebulizer with replaceable capillary
• Heated PFA spray chamber for high sample transport efficiency
• Both nebulizer and spray chamber are behind a secured door to alleviate electrostatic effects
• Patented PTFE membrane desolvator for lowest oxide and hydride levels
• Built-in gas flow controllers for both argon sweep gas and N2 addition gas
• Built-in spray chamber drain pump with acidresistant PVDF parts
• Dedicated, adjustable temperature controllers for both spray chamber and membrane desolvator
• Modular membrane desolvator for easy cleaning and/or replacement
