An instrument for extraction based molecular sample preparation and related processes is disclosed. The instrument includes a thermally conductive pressure resistant heating chamber and a thermally conductive sample cup positioned in the thermally conductive pressure resistant healing chamber for heating liquids and solids together in the thermally conductive sample cup. A liquid delivery inlet fixture in the thermally conductive pressure resistant heating chamber delivers liquids (solvent) from a supply to the thermally conductive sample cup in the thermally conductive pressure resistant heating chamber, and a chiller in liquid communication with the thermally conductive sample cup in the thermally conductive pressure resistant heating chamber receives heated liquids from the thermally conductive pressure resistant heating chamber when the chamber is opened to atmospheric pressure.

This application is related to application Ser. No. 15/644,920 filed concurrently herewith for Rapid Sample Preparation for Analytical Analysis Using Dispersive Energized Extraction and application Ser. No. 15/644,950 filed concurrently herewith for Rapid Energized Dispersive Solid Phase Extraction (SPE) for Analytical Analysis.
The present invention relates to analytical chemistry, and in particular relates to sample preparation for molecular analysis.
In order to carry out molecular analysis (the task of identifying one or more compounds in a sample) of any product, a sample of the product must be in such a form that it can be easily analyzed by chromatography, spectroscopy, mass spectroscopy and/or nuclear magnetic resonance instrumentation

In general, terms are used herein in a manner that is clear from the context of this specification, or as explicitly stated, or using standard English dictionary definitions.
The term “solvent” is used in its well understood chemical sense; e.g., “a substance capable of dissolving another substance (solute) to form a uniformly dispersed mixture (solution) at the molecular or ionic size level.” The adjective “organic” is used in its well understood sense to “embrace all compounds of carbon” other than certain small molecule combinations of carbon with oxygen, sulfur, and metals, and in some cases halogens. See, Lewis, Hawley's Condensed Chemical Dictionary, 15th Edition, 2007, John Wiley & Sons
The “sample matrix” is the material to be tested for the presence and optionally the amount of analyte.
