Perkin Elmer, WE025221, Cyclonic Spray Chamber for ELAN DRC

The spray chamber is an integral part of the sample introduction system responsible for ltering the sample mist to permit the appropriate droplet size distribution to reach the plasma. The baffed cyclonic spray chamber features a central transfer tube which acts as a secondary particle separator helping separate larger aerosol particles from the sample. This reduces solvent load in the plasma without compromising detection limits. The distance between the bottom of the baffle and the chamber wall is carefully controlled so that droplets cannot form on the bottom of the baffle. The advantage is smooth draining and improved precision.
