Detail:
The OpalMist DC Nebulizer differs from the traditional OpalMist nebulizer primarily in its argon gas connector, featuring a UniFit sample connector and an instrument-specific Direct Connect flexible argon gas line for a more direct and reliable connection.
The OpalMist concentric nebulizer is the most economical nebulizer for high precision analyses involving samples digested in HF. Glass Expansion DC (Direct Connection) nebulizer has a UniFit sample connector which slides easily over the sample arm and an argon gas connector configured to connect directly to your ICP-MS.
What is an OpalMist DC Nebulizer?
In ICP (Inductively Coupled Plasma) analysis, an OpalMist PFA nebulizer is a type of nebulizer with a design specific for high-precision analysis, especially ICP-MS. It uses a PFA (Perfluoro alkoxy) material for its construction, offering high chemical resistance and low background contamination.
The DC nebulizer is designed for a more direct and secure connection to the ICP instrument, while the traditional OpalMist nebulizer uses a different connector type and may have features focused on nebulizer performance and durability.
How is an OpalMist Nebulizer Different from Other Nebulizers in ICP?
The OpalMist nebulizer, made of ultra-high-purity PFA, stands out for its high chemical resistance to HF, alkalis, and organics. It is suitable for ultra-trace ICP-MS work due to its low elemental background levels.
A critical details checklist supporting the unique qualities of OpalMist includes:
- Materials: As mentioned, the OpalMist nebulizer is constructed from PFA (perfluoro alkoxy), a high-purity fluoropolymer, which is known for its inertness and resistance to chemicals.
- Chemical Resistance: Importantly, the PFA material provides superior resistance to corrosive samples, including those containing HF, alkalis, and organics, making it work for many applications.
- Ultra-Trace Analysis: The high purity of the PFA construction results in very low elemental background levels, which is crucial for ultra-trace analysis, especially in ICP-MS.
- Self-Aspiration: The OpalMist, with its design for self-aspiration, removes the need for peristaltic pump tubing, and therefore removes a primary source of contamination.
- Applications: OpalMist is ideal for labs requiring increased resistance to harmful sample types and/or ultra-trace analyses.
What Stands Out About the OpalMist DC Nebulizer?
Primarily, it’s the Argon Gas Connector featuring a UniFit sample connector that slides over the sample arm and an instrument-specific Direct Connect flexible argon gas line.
The benefits are:
- Inert metal-free argon gas connector.
- Reliable ratchet fitting ensures leak-free argon gas connection.
- High physical reproducibility (~3%).
- Strong and consistent self-aspiration.
- High tolerance to particulates (up to 75µm depending on uptake).
- TDS tolerance, typically up to 15%.
- Low RSD’s due to concentric geometry.
- Uses only standard ICP argon supply pressures
