OpalMist DC Nebulizer 2mL/min
The OpalMist™ PFA DC concentric nebulizer is the nebulizer of choice for high precision analyses requiring the highest chemical resistancy to HF, alkalis and organics. The high purity PFA construction makes it ideal for ultra-trace ICP-MS work. The self-aspiration properties of the nebulizer eliminate the need for peristaltic pump tubing which can be source of contamination. The inert construction of the OpalMist PFA nebulizer enables it to easily handle even the most corrosive samples, such as those containing high levels of hydrofluoric acid (HF) or reactive organic solvents. The OpalMist is also capable of aspirating high concentrations of dissolved solids (typically up to 15%) without clogging. This makes the OpalMist the ideal nebulizer to handle geochemical samples which are typically dissolved in HF and are high in dissolved solids. The small mean droplet size of the OpalMist™ enhances transport efficiency without increasing noise. For ICP-MS, the high purity of PFA makes it the preferred nebulizer for ultra-trace analyses.

Features
- Ideal for High Purity and High Chemical Resistance
- Ultra-Trace Analysis: The high purity of the PFA material used to make the OpalMist nebulizer provides the exceptionally low background necessary for ultra-trace determinations.
- Highly Corrosive Samples: The inert construction of the OpalMist PFA nebulizer enables it to easily handle even the most corrosive samples, such as those containing high levels of hydrofluoric acid (HF) or reactive organic solvents.
- Excellent Sensitivity: The small mean droplet size of the OpalMist™ enhances transport efficiency without increasing noise.
- Robust and Consistent Self-Aspiration: Self-aspiration eliminates the need for peristaltic pump tubing, a potential source of contamination.
- Suitable for all ICP-MS and ICP-OES models: For ICP-OES, it is the nebulizer of choice when samples contain both high dissolved solids and HF, but do not contain large particulates (75µm). For ICP-MS, the high purity of PFA makes it the preferred nebulizer for ultra-trace analyses.
- Chemical Resistance: Superior resistance to a wide range of corrosive chemicals, including strong acids (such as hydrofluoric acid), alkalis, and organic solvents.
- Low Contamination: PFA's inert nature results in minimal contamination or leaching of elements into samples, ensuring high purity and accuracy in trace element analysis.
- Application Flexibility: PFA nebulizers are widely used in ultra-trace analysis applications due to their low elemental background levels and high purity construction, making them particularly suitable for demanding analytical techniques like ICP-MS.
- Specialized Application: Ideal for handling geochemical samples dissolved in HF and high in dissolved solids.
