ABSTRACT:
An improved microprocessor-controlled autosampler for use in liquid chromatography is shown. The autosampler is fully programmable by the operator and capable of performing complex sample preparation routines. A spring-loaded sample needle is employed to ensure that the needle makes contact with the bottom of the sample vial as required, for example, when handling extremely small samples. A hollow vial lifter serves as the receptacle for waste wash solvent eliminating the need for a special waste receptacle mechanism. Other improved features include a plurality of interchangeable, codable sample racks, a four-way valve in the syringe line enabling rapid priming/purging of the hydraulics, and as improved vial stabilizer design.
