  • Patent number: 8281500
    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.
    Type: Grant
    Filed: October 26, 2009
    Date of Patent: October 9, 2012

  • Patent number: 8061056
    Abstract: This disclosure describes a sample drying system and method that provides a high rates of evaporation and sublimation that is commonly employed in compound processing procedures. The drying increases the sample-solute concentration and removes the solvent completely to produce the dried sample as a non-volatile solute precipitate. Re-circulating of drying gas is disclosed along with a solvent cold trap.

  • Patent number: 6783649
    Abstract: The invention is directed to a high throughput capillary electrophoresis (CE) system, which comprises multiple mobile CE detector modules that are transportable by a programmable fluid-handling arm assembly to fixed samples in microtiter plate wells for analysis. The CE system of the invention is capable of simultaneously automating sample preparation and multiple CE analysis of the sample in a continuous timely process. The CE detector modules of the invention may be equipped with any suitable detection method, such as an ultraviolet (UV) absorbance or a laser-induced fluorescence (LIF) detector.
