 Overview

The CETAC AridusII Desolvating Nebulizer System is a specialized sample introduction accessory for ICP-MS, providing up to 10x signal enhancement and reduction of solvent based mass spectral interferences.

Sensitivity Enhancement for ICP-MS:  The AridusII can help typically enhance analyte element sensitivity by a factor of 4x to 10x (depending on sample uptake rate) vs. the standard pneumatic nebulizer.

Reduced Interferences:  The AridusII features an inert, fluoropolymer desolvating membrane apparatus for efficient removal of water vapor;  the %CeO/Ce is usually 0.05% or less.

Low-Flow PFA Nebulizers:  Low-flow (50, 100 or 200 microliters/min) CFlow PFA nebulizers are available for introduction of corrosive, low-volume samples.

Heated PFA Spray Chamber with Drain:  A heated PFA spray chamber improves sample aerosol transport efficiency.  A built-in drain pump removes any excess sample liquid to waste.

Protection for PFA Nebulizer and Spray Chamber:  Both the PFA nebulizer and PFA spray chamber are behind a secured door to alleviate electrostatic effects.

On-board Gas Flow Control:  Gas flow controllers are included for both the argon sweep gas and nitrogen addition gas.

Dedicated Temperature Controllers:  Dedicated, adjustable temperature controllers are included for both the PFA spray chamber and the membrane desolvator.

Modular Membrane Desolvator:  The membrane desolvator assembly is a modular unit which can be easily removed for cleaning and/or replacement.

Easy Setup:  All AridusII units are provided with a completion kit and an interface kit for quick and easy connection to the hostICP-MS.  The kit includes a nebulizer gas line and a sample out line with the appropriate ICP torch adapter.  In addition, a rinse kit is included for cleaning the membrane desolvator.

Optional Accessories:  Optional accessories for the AridusII include the ASX-112FR MicroAutosampler for automated sample introduction and the QuickWash Rapid Washout Accessory for in place cleaning of the PFA spray chamber.
