Great results, could not live without it!

  • Application Area: MC-ICP-MS Isotopic analyses

"The Aridus II is pretty much an industry standard (the industry being isotope geochemistry research). I believe the Aridus provides the best senstivity for desolvation. The Aridus II model is susceptible to changes in atmospheric conditions. I notice drops in sensitivity even from opening the door to the lab. Walking by the Aridus, or touching it in any way, also destabilizes the beam. Therefore, I typically set up autosampler sequences at the end of the day and leave it to run overnight so no one is in the lab to interfere. I have also had issues with the connects and tubing, but replacing them is not a huge issue. Overall, for all the complaints I have about it, I still use it for certain applications that I do not think would be possible without it. I am hoping to purchase an Aridus 3 soon, and was excited to see a new model has come out."

Depending on the application, we are more or less satisfied.

  • Application Area:Sample indroduction for isotope geochemistry

"The product works well for certain applications (mainly heavier isotopes like Hf, Sr and Pb), but for others we fail to achieve satisfying results (e.g. Si, Fe) and have to use a different product (usually Apex). The sweep gas needs to be tuned quite often and the intensity varies which makes it unsuitable for concentration measurements of samples."

  • Application Area:Analysis of radiogenic isotopes by MC-ICPMS

"Since Septermber 2017 we have installed a new MC-ICPMS (Nu Instruments Plasma 3). After some recommendations and many years working with APEX I decided to purchase an Aridus II. I had experience with Aridus I several years ago. So far extremely dissapointed. The Aridus II is simply not stable or ready for measuring low abundance radiogenic isotopes (Nd). The sweep gas system stability is a nightmare. We don't even use N2, but the sweep gas out is completely unreliable and keeps losing its optimization. There is also the issue of droplets in the tube that goes from the acid bottle trap to the exhaust. If there is condensation there you are basically done as the signal instability will increase. Not only signal intensity but also isotopic ratios are highly dependent on the sweep gas. We haven't managed to get stable runs for more than a few hours before we have to re-tune the sweep gas. At this point it is impossible to run the instrument unattended with the autosampler. We are seriously considering in purchasing an APEX for these reasons."

The Aridus II Desolvating Nebulizer System is a specialized sample introduction accessory for Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

The Aridus II can enhance analyte sensitivity up to 10 times and can greatly reduce solvent-based interferences such as oxides and hydrides. The Aridus II 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 Aridus II 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 Aridus II™ 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).

 

Key Features:

  • Sensitivity enhanced by a factor of 4 to 10 times
  • Low volume sample uptake rates of 50, 100 or 200 μL/min
  • Unique, tunable Aspire™ PFA Nebulizer with replaceable capillary
  • Heated PFA spray chamber for high sample transport efficiency
  • Both nebulizer and spray chamber are behind a secured door to alleviate electrostatic effects
  • Patented PTFE membrane desolvator for lowest oxide and hydride levels
  • Built-in gas flow controllers for both argon sweep gas and N2 addition gas
  • Built-in spray chamber drain pump with acidresistant PVDF parts
  • Dedicated, adjustable temperature controllers for both spray chamber and membrane desolvator
  • Modular membrane desolvator for easy cleaning and/or replacement
