ICP - Spray Chamber

To improve aerosol performance, techniques are used to classify the droplets before the aerosol is transported to the plasma.

This results in a narrow distribution of droplet sizes being introduced into the plasma, preferably with a small mean droplet diameter.

The most effective way to accomplish this classification is to use a spray chamber, which provides an expansion chamber and a circuitous route for the droplets to travel en route to the plasma.

The larger droplets, which have higher momentum, collide with the walls of the spray chamber where they are condensed.
Only the smallest diameter particles survive the process and are transported through the system for the use of a spray chamber to classify aerosol droplet size.

The bimodal distribution with a measurable quantity of large-diameter droplets. After passing through a spray chamber, the size distribution is much narrower and exhibits a smaller mean droplet diameter.
Several configurations and designs of spray chambers are prevalent and are used with different types of nebulizers.
