Abstract
A drying container insert that manages the evaporation rate of liquid solutions when subjected to blow-down gas flows. Certain gas flow separator baffles or framed inserts with vanes may be especially effective to enhance evaporation when combined with aggressive blow-down flow rates and centrifugal force. The centrifugal force applied to the evaporating liquid protects sample integrity by preventing the solution(s) from splashing out of the drying container. Such splashing, when high blow-down gas flow rates are directed into the sample containers, affects yield and purity.
