The 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.

The Aridus3 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 Aridus3 is particularly advantageous for small volume and highly corrosive samples such as those generated in the earth sciences and the semiconductor industry.

The sample path (nebulizer, spray chamber, and membrane) is composed 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, depending on ICP-MS model and operating conditions).

The Aridus3 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. Sample runs with the Aridus3 can be automated with the CETAC ASX-112FR MicroAutosampler.

Features

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
