Abstract

A sample treatment system for automated extraction of compounds is disclosed. The system includes a housing defining an enclosure including a top cover having open ended chambers to receive sample plates on an interposed carriage frame, an automated shuttle means for lateral transportation and vertical lifting of the carriage frame to selectively address the chamber below the sample plate for the throughpassage of fluid from the sample plate and urged by a vacuum pump for evacuating air from a chamber to a degree below atmospheric pressure for through passage of fluid from the sample plate to either a waste plate or a collection plate. The shuttle means includes motor drives for precisely laterally and vertically positioning the carriage frame.
