Detail:
DuraMist Nebulizer is an HF-resistant nebulizer, that provides excellent sensitivity and precision at an affordable price. The DuraMist is a concentric, self-aspirating nebulizer. It is compatible with all ICP models’ ability to run samples with up to 30% total dissolved solids without blockage making it a universal nebulizer. The strength and rigidity of the PEEK material allow the DuraMist to be manufactured to very tight tolerances, enabling it to closely match the SeaSpray, the worldwide market-leading high-performance glass nebulizer. A comparison of the DuraMist with the SeaSpray showed that the DuraMist gave a similar performance.
What are the Key Features of the DuraMist Nebulizer?
- Inert Material: Constructed from PEEK (polyether ether ketone). That is because this robust and inert material resists corrosion and chemical attack, including from acids like HF.
- Concentric Design: The concentric design has a smooth capillary tip. As a result, it contributes to high sensitivity and excellent precision.
- High Tolerance to Dissolved Solids: The smooth surface of the capillary and nebulizer tip allows for a high tolerance to dissolved solids, typically up to 30%.
- HF Resistance: It is designed to handle samples containing up to 5% hydrofluoric acid (HF).
- High Physical Reproducibility: Minimal nebulizer-to-nebulizer variability. This ensures consistent analytical performance.
- Self-Aspirating: The DuraMist is a self-aspirating nebulizer. For example, it draws the sample into the nebulizer without the need for an external pump.
- Direct Connect: The DuraMist DC nebulizer features a direct connect installation. As a result, it seamlessly integrates with various ICP-OES and ICP-MS models.
- UniFit Sample Connector: The UniFit sample connector provides an excellent seal and a zero-dead-volume connection.
- Compatible with LC Interface: The sample arm of the DuraMist is compatible with Glass Expansion’s Liquid Chromatography (LC) interface kit.
How does the DuraMist Differ from Other ICP Nebulizers?
- Material: Unlike traditional glass or quartz nebulizers, the DuraMist is made of inert PEEK, making it suitable for samples containing HF and other corrosive acids.
- Concentric vs. Parallel-Path: While parallel-path (or v-groove) nebulizers are designed to resist blockages, they may have larger droplets and a wider droplet size distribution, potentially affecting efficiency and precision. The DuraMist’s concentric design offers a balance of sensitivity and tolerance to dissolved solids.
- Dissolved Solids Tolerance: The DuraMist has a higher tolerance to dissolved solids compared to some other concentric nebulizers, allowing for the analysis of a wider range of samples.
- Applications: While concentric nebulizers are ideal for routine analysis of aqueous samples, the DuraMist is a versatile “all-rounder” suitable for a variety of sample types, including those containing HF and high concentrations of dissolved solids.
