Detail:
Nebulizer Sample Quick Disconnect includes Teflon insert with PTFE capillary tubing (1.6mm OD x 0.5mm ID x 18″ long) – 1 Red O-ring.
In an ICP system, nebulizer fittings refer to the specific connectors and attachments used to connect the liquid sample delivery line to the nebulizer. The nebulizer, of course, is the component responsible for converting the liquid sample into a fine mist for introduction into the plasma. Essentially, the fittings, such as FI Nebulizer Sample Quick Disconnect 500-QD-FI-1, are the parts that allow the sample solution to be precisely delivered into the nebulizer for analysis.
Function of Nebulizer Fittings
Nebulizer fittings ensure a tight, leak-free connection between the sample tubing and the nebulizer. In doing so, the fittings prevent any disruptions in the sample flow that could affect the accuracy of the analysis.
Types of Nebulizer Fittings
Depending on the nebulizer design, fittings may include:
- Sample inlet connector: The part where the sample tubing is attached directly to the nebulizer.
- Gas inlet connector: For connecting the carrier gas line to the nebulizer (if applicable).
- O-rings or seals: Used to create a tight seal around the connections and prevent leaks.
The Quick Disconnect Function
A “quick disconnect” on a nebulizer fitting in ICP (Inductively Coupled Plasma) allows for the rapid and easy attachment and detachment of the gas supply line to the nebulizer. As a result, quick switching between samples or cleaning procedures can occur without the need for time-consuming, fiddly connections or disconnections. Essentially, it provides a convenient way to quickly connect and disconnect from the gas source to the nebulizer.
- Ease of use: The quick disconnect mechanism allows for fast and simple connection/disconnection of the gas line. Of course, this is particularly useful when frequently switching between samples or performing cleaning procedures.
- Minimized contamination risk: By quickly disconnecting the gas line, the potential for cross-contamination between samples is reduced.
- Maintenance convenience: The quick disconnect feature facilitates easy removal of the nebulizer for cleaning and re-installation.
Material Considerations in Nebulizer Fittings
Fittings are often from materials like PEEK (polyether ether ketone) or PFA (perfluoroalkoxy polymer) to resist corrosion from aggressive chemicals commonly in ICP analysis.
