Auto sample handlers for chromatography systems generally comprise a carrier for holding a multiplicity of liquid samples in vials. The carrier is moved so as to successively bring the vials beneath a syringe which is actuated to withdraw the sample and inject it into the chromatography system. Quite often, such auto sample handlers comprise at least two motors for moving the carrier in two directions to bring the sample vials into the desired position. Further, some sample handlers require that after the sample is withdrawn from a vial, the entire carrier has to be moved out of the way in order to inject the sample into the chromatography system.
