Teledyne CETAC is one of the industry leaders in nebulizer systems, offering a comprehensive line of specialized sample introduction accessories for ICP-AES and ICP-MS. Among our systems are the Marin-5 Enhanced Nebulizer System, the U5000AT+ Ultrasonic Nebulizer, the U6000AT+ Ultrasonic Nebulizer & Membrane Desolvator and the Aridus II Desolving Nebulizer. The newest member of the CETAC sample introduction family is the Aridus3 Desolvating Nebulizer System, which is a 4th generation of a specialized liquid sample introduction accessory for ICP-MS.
The Aridus3 offers analyte element sensitivity that is enhanced 10 times or greater and significant reduction of solvent-based interferences such as oxides and hydrides. Aridus is widely used in a variety of ICP-MS applications, including geochemistry, geology, clinical, pharmaceutical and semiconductor. The Aridus3 can be used in a variety of ICP-MS applications, including geology, semi-conductors, pharmaceuticals, and clinical samples.
In a news release, Teledyne CETAC Nebulizer Product Manager Fred Smith said, The Aridus3 offers a number of important new benefits based on feedback from AridusII customers around the world.”
Among the key benefits of the Aridus3 system are the following:
- Enhanced analyte sensitivity (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 preset shut off of 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
Significant upgrades with the Aridus3 include new; dedicated mass-flow controllers with computer software control that set the Ar sweep gas and N2 addition gas glows, easing the tuning process. A novel removable membrane oven assembly greatly simplifies cleaning and maintenance, while a software Flow Saver application allow preset shut-off of valuable gases after long unattended sample runs.
Smith added, “The development of new and improved accessories for the atomic spectroscopy marketplace is a constant process at Teledyne CETAC and this will continue with the Aridus product line.”
