Pre-injection chromatographic sample sequencer

摘要

A pre-injection sample sequencing subsystem for laboratory apparatus which includes a chromatograph with a column includes a circular tray with a plurality of concentric arrays of physical locations for storing sample vials in radially extending linear arrays, and a plurality of virtual locations that are extensions of the linear arrays. Each of the physical and virtual locations are individually addressable by a controller for a robot on the tray such that pre-injection sample processing modules may be attached to the tray, located at one or more of the virtual locations. A sequencing method optimizes transfer of samples contained in the vials between their respective physical storage location and the pre-injection processing modules.
