Abstract
An apparatus for determining one or more elements or compounds in a laboratory sample, and for simultaneously performing both vapor generation and nebulization in one device, is disclosed. The apparatus comprises an enclosed cyclonic spray chamber with two integrally affixed cylindrical ports, one for introducing a nebulizer into the chamber and the other for facilitating volatilization of analytes within the chamber. In addition, two conical tubes are integrally affixed to the chamber and oriented opposite each other, with one tube serving as the means for introducing a sample into the spray chamber, and the other tube serving as the means for introducing reductant/reactant into the spray chamber. This invention allows a sample that has been introduced into the spray chamber to be subjected to nebulization or vapor generation, or to both processes.
