The Aridus3 Desolvating Nebulizer System is a specialized sample introduction accessory for Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
The Aridus3 can enhance analyte sensitivity up to 10 times and can greatly reduce solvent-based interferences such as oxides and hydrides. The Aridus3 couples the C-flow PFA nebulizer and a heated PFA spray chamber with a PTFE membrane desolvator unit. 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 (e.g. HF) such as those generated in the earth sciences and the semiconductor industry.
The Aridus3; can be easily interfaced with all current t ypes of ICP-MS instruments, including quadrupole, high-resolution (HR), multi-collector (MC) and time of flight (TOF) systems. The sample path (nebulizer, spray chamber and membrane), are all made of inert 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 usually 0.05% or less).
