Detail:
Direct Connection (DC) Nebulizer
The Slurry DC Nebulizer is designed for introducing slurries, suspensions, and wear metals into an ICP instrument. It’s a specialized type of nebulizer that offers advantages like reduced blockage, improved signal stability, and the ability to handle undissolved particles up to a certain size.
What is the Slurry DC Nebulizer Best For?
The Slurry glass concentric nebulizer is ideal for applications requiring the aspiration of slurries or suspensions. Its capillary bore is 50% larger than standard concentrics, which reduces the possibility of particle blockage while giving excellent signal stability.
- Material: Borosilicate glass
- High physical reproducibility ~ 1%
- TDS tolerance, typically ~ 1%
- High tolerance to particulates, typically up to 150um
- Low RSD’s due to highly accurate construction
- Slurry nebulizers have a natural liquid uptake of 4mL/min but operate best between 1.5 – 2.5mL/min
Does the Slurry DC Nebulizer have Advantages in ICP?
Yes, the Slurry DC Nebulizer does have advantages in ICP, such as:
- Handles Slurries and Suspensions: The large capillary bore (50% larger than standard concentrics) of the Slurry DC Nebulizer reduces the risk of particle blockage, making it suitable for samples containing undissolved particles.
- Improved Signal Stability: The larger capillary bore also contributes to better signal stability.
- Tolerant of Undissolved Particles: It can handle undissolved particles up to 150 microns in diameter.
- Direct Connection: The DC design features a direct connection to the ICP instrument, minimizing dead volume and improving efficiency.
- Ease of Use: The UniFit connector and direct connection design simplify the process of connecting the nebulizer to the ICP instrument.
- Self-Aspiration: Some Slurry DC Nebulizers, like the OpalMist™ PFA DC Concentric Nebulizer, offer self-aspiration, eliminating the need for peristaltic pumps and potential contamination.
In essence, the Slurry DC Nebulizer is a valuable tool for analyzing samples that contain suspended solids or undissolved particles, offering advantages in terms of blockage resistance, signal stability, and ease of use within the ICP analytical workflow.
