The Teledyne CETAC Aridus3 Desolvating Nebulizer System is a specialized liquid sample introduction accessory for inductively coupled plasma mass spectrometry (ICP‑MS). The Aridus3 can enhance analyte sensitivity up to 10 times or more ​​​and can greatly reduce solvent-based interferences such as oxides and hydrides.​ Download the Prod​uct Brochure​​ for additional information.



  • 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

  • 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

  • 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​
