Product Features
Ultra-Trace Analysis: When carrying out ultra-trace analysis, especially by ICP-MS, the risk of contamination must be minimized. The high purity of the PFA material used to make the OpalMist nebulizer provides the exceptionally low background necessary for ultra-trace determinations.
Handling Highly Corrosive Samples: The totally 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.
High sensitivity and precision: The rigidity of the PEEK body allows for manufacturing with high physical reproducibility, resulting in an inert concentric nebulizer design that does not compromise sensitivity and precision for demanding ICP-OES and ICP-MS applications. A comparison of the DuraMist DC with the SeaSpray DC, our worldwide market-leading high performance glass nebulizer, showed that the DuraMist DC gave similar performance.
Excellent Sensitivity: The small mean droplet size of the OpalMist™ enhances transport efficiency without increasing noise.
Robust and Consistent Self-Aspiration: Available with natural uptake rates of 0.01, 0.05, 0.1,0.2, 0.4, 0.6, 1 and 2mL/min. Self-aspiration eliminates the need for peristaltic pump tubing, a potential source of contamination.
High Physical Reproducibility: Approximately 1%. Meets stringent Quality and Reproducibility Standards expected from Glass Expansion.
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.
Benefits of PFA Nebulizers
Chemical Resistance: PFA nebulizers exhibit 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.
Direct Connection (DC) Nebulizer
The DC nebulizer has a UniFit sample connector that slides easily over the sample arm and an argon gas connector configured to connect directly to your ICP. The benefits of the DC nebulizer are:
- Inert metal-free argon gas connector.
- Instrument-specific Direct Connect flexible argon gas line.
- Reliable ratchet fitting ensures leak-free argon gas connection.
DC versions of the SeaSpray, MicroMist, Conikal, Slurry, DuraMist, OpalMist, and VeeSpray nebulizers are available to suit the most common models of ICP-OES and ICP-MS.
The DC nebulizer part number has a prefix specific to each type of gas connector. For example, the prefix "A13-" denotes a connector for the Agilent ® 5100, 5110, 5800, 5900 ICP-OES, so part number A13-07-USS2 is a SeaSpray nebulizer configured for direct connection to the Agilent ® 5100, 5110, 5800, 5900. See Understanding Glass Expansion nebulizer part numbers for a full list of available DC nebulizers, or Choose a Nebulizer to suit your ICP to see the DC nebulizers for your particular ICP model.

Nebulizer Maintenance Made Easy
If the sample capillary becomes blocked with particulates, use the Eluo Nebulizer Cleaning Tool to remove the blockage. For the DuraMist and OpalMist nebulizers, use the Eluo OPD version (P/N 70-ELUO-OPD). Regular use of the Eluo will help keep your nebulizer clean and in good condition.
If blockages due to particulates are a frequent issue for your laboratory, consider adding the re-useable Guardian in-line filter (P/N 70-803-1108). The Guardian in-line filter provides a simple and effective way to eliminate the risk of a blockage. And the filter can be cleaned using a simple attachment for the Eluo (P/N: 70-803-1160).
To keep your DuraMist nebulizer in optimum condition, follow our detailed nebulizer maintenance procedures listed in our Nebulizer Maintenance flyer.
