Abstract
A sequential combination solvent removal system comprising at least one low temperature condenser solvent removal system interconnected to at least one enclosed filter solvent removal system is described. The sequential combination solvent removal system is capable of providing stable levels of solvent vapor in exiting mixtures of solvent vapor and nebulized sample particles, whether the solvent is aqueous or organic, and regardless of the type of sample solution nebulizer used to provide nebulized sample solution droplets to a preceding desolvation system, or of the flow rate of solvent vapor into said sequential combination solvent removal system. In the preferred embodiment a low temperature condenser solvent removal system is first in line and is followed by a functionally attached enclosed filter solvent removal system. A plurality or multiplicity of low temperature condenser and enclosed filter solvent removal systems can be present in modified embodiments in any order, and with or without intervening desolvation systems.
