Abstract
Official abstract text for this publication.
A method of extracting an analyte from a sample is described. The sample is added to a sample container. A liquid solvent and a gas are added into the sample container. The addition of the gas is controlled to establish an elevated pressure within the sample container. The liquid solvent is heated to an elevated temperature that is below the boiling temperature of the liquid solvent at the elevated pressure. A type of gas is used that does not transition to a supercritical fluid at the elevated temperature and pressure used in the extraction process. The analyte can dissolve from the solid sample into the liquid solvent. Next, at least a portion of the liquid solvent containing the dissolved analyte can be removed from the sample container for subsequent analysis.
First claim
Opening claim text (preview).
What is claimed is: 1 . An apparatus configured to extract an analyte from a first sample, the apparatus comprising: a compressed gas source configured to supply a gas at a superatmospheric pressure; a liquid solvent pump configured to transport a liquid solvent; a fluid junction including a first inlet, a second inlet, and an outlet, where the first inlet and second inlet are both fluidically connected to the outlet, the first inlet also being in fluidic communication with…
