Teledyne CETAC Aridus 3
The Teledyne CETAC Aridus 3 Desolvating Nebulizer System is a specialized liquid sample introduction accessory for inductively coupled plasma mass
spectrometry (ICP‑MS). The Aridus 3 can enhance analyte sensitivity up to 10 times or more and can greatly reduce solvent-based interferences such as
oxides and hydrides.
Introduction
The Aridus 3 couples a low-flow (50, 100, or 200 μL/min) PFA nebulizer and a heated PFA spray chamber with an inert fluoropolymer membrane. This combination
provides enhanced analyte sensitivity while reducing solvent based interferences such as oxides and hydrides.
The Aridus 3 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 Aridus 3 can be easily interfaced with all current types of ICP‑MS instruments, including quadrupole (Q), high resolution (HR), multicollector (MC), and time of flight (TOF) systems.
The sample path (nebulizer, spray chamber, and membrane) are all made of 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 typically 0.05% or less).

Benefits
- Analyte sensitivity enhanced up to 10 times or more, depending on liquid sample uptake rate
- Low-volume sample uptake rates of 50, 100, or 200 microliters/min, preserving valuable sample
- Low-volume sample uptake rates of 50, 100, or 200 microliters/min, preserving valuable sample
- C-Flow PFA nebulizer with integrated autosampler probe for use with Teledyne CETAC ASX‑112FR MicroAutosampler
- Heated PFA spray chamber for higher sample transport efficiency
- Both PFA nebulizer and PFA spray chamber are behind a secured door to alleviate electrostatic effects
- Both PFA nebulizer and PFA spray chamber are behind a secured door to alleviate electrostatic effects
- Inert fluoropolymer membrane for resistance to acids (including HF) and low oxide and hydride levels
- Built-in mass flow controllers (MFCs) for precise setting of Ar sweep gas and N2 addition gas
- Convenient computer software control of spray chamber temperature, membrane oven temperature and both Ar sweep gas and N2
addition gas allows remote tuning if the Aridus3 is placed in a clean enclosure - New Flow Saver software application allows the user to turn off Ar and N2 gas flows after completion of an overnight run, saving valuable gases.
- New removable membrane heater block for ease of cleaning or replacement
