  • ​​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 µL/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

Software Control of Gas Flows and Temperatures​​

​The Aridus3 is equipped with dedicated mass flow controllers (MFCs) for precise control of both the Ar sweep gas and N2 addition gas flows. Control is also provided for the PFA spray chamber and membrane oven temperatures. An easy to use software interface (which can be loaded onto the host ICP-MS computer or a separate computer such as a laptop) allows ease of parameter tuning and minimizes any manual user interaction with the Aridus3. The latter feature is an important benefit if the Aridus3 must be placed in a special enclosure such as a clean box. 

In addition to temperature and gas flow control, the Aridus3 software has a new Flow Saver timing function that allows the user to turn off the Ar sweep gas and N2 addition gas flows at a predetermined time. This benefit saves valuable gases after a longer unattended sample run.

Removable Membrane Desolvator Module

The Aridus3 is equipped with a removable membrane desolvator module. The module is an integral part of the Aridus3 chassis and simply pulls directly out of the back panel (no need to open the main cover). Once removed from the Aridus3, the membrane desolvator module can be conveniently cleaned or replaced. A dedicated rinse kit is provided to introduce an appropriate cleaning solution such as dilute nitric acid.​​

C‑Flow PFA Concentric Nebulizer

Optimized for the Aridus 3/ASX-112FR: C-Flow PFA nebulizers for the Aridus3 are factory adjusted for best performance in the heated PFA spray chamber and feature a built-in autosampler probe for connection to the ASX-112FR MicroAutosampler.

Low-Flow Rates Available: The C-Flow PFA Nebuliz er for the Aridus3 is available in three self-aspiration flow rates of 50 µl/min, 100 µL/min, and 200 µL/min.

​Option: ASX-112FR Micro Autosampler​​

The ASX-112FR (Flowing Rinse) MicroAutosampler  is designed for use with the Aridus3. The ASX-112FR offers the benefits of a transparent protective cover and a dual flowing rinse station to ensure sample integrity from the first to the last sample in a sequence. All sample vials, racks, and trays are constructed of metal-free, acid-resistant polymer materials. A hinged door in the front of the cover allows easy access to sample and standards. 

There are five standard positions for 20-mL PFA vials and nine stan dard positions for 4-mL PFA vials. Sample racks include 24, 48, and 96 position types for 0.5 mL to 2.0 mL sample volumes. Bel-Art half racks (30 and 42 position) for 7-mL and 14-mL samples are also available.

The modular design of the ASX-112FR allows placement on the Aridus3 cover for maximum conservation of valuable benchtop space. This arrangement also minimizes sample path length using the C-Flow PFA nebulizer with integrated sample probe. Computer interfaces include RS-232 and USB. ​​

​

Sample solution is introduced ​to the Aridus3 by a self-aspirating C-Flow PFA nebulizer. The nebulizer aerosol is sprayed into a heated (up to 110°C) PFA spray chamber to maintain the sample in a vapor phase. The sample vapor then enters a heated fluoropolymer membrane desolvator (140°C) module.

A counter-current flow of argon sweep gas is added to remove solvent vapors that permeate the porous wall of the membrane. Non-volatile sample components do not pass through the membrane wall and continue to the ICP-MS instrument.​​
