In the Cross-Flow Nebulizer system, what causes the conversion of solution filaments into an aerosol spray?
High speed stream of Ar gas
In an ICP-OES system, what is the primary function of a spray chamber?
To separate large droplets from small droplets and transport the latter to the plasma torch.
What is a common material used in the construction of a Scott Spray Chamber in an ICP-OES system?
Ryton (corrosion-resistant material)
What is the main function of a Cyclonic Spray Chamber in an ICP-OES system?
To separate large aerosol droplets downward and carry fine droplets upward to the plasma torch.
What is the advantage of the axial view in ICP-OES over the radial view?
Higher sensitivity and lower detection limit
Why is the SCD detector cooled at -35°C with a chiller in ICP-OES?
To improve the detection of resonance emission wavelengths
What is a unique feature of the Segmented Array Charged Coupled Device Detector (SCD) in ICP-OES?
It can measure thousands of emission wavelengths simultaneously
How does the cross-flow nebulizer contribute to ICP-OES analysis?
By producing a finer aerosol for efficient sample introduction
