Automatic sample manager

A liquid chromatography system includes a solvent delivery system; a sample manager including a sample delivery system in fluid communication with the solvent delivery system, the sample delivery system configured to inject a sample from a sample vial into the chromatographic flow stream; a liquid chromatography column downstream of the sample delivery system; and a detector downstream of the liquid chromatography column. The sample delivery system further includes a first needle driver including a first sample needle configured to extract a sample from the sample vial and deliver the sample to the liquid chromatography column; and a first syringe in communication with the first sample needle, the first syringe configured to meter an extraction amount of the sample from the sample vial. The sample manager further includes a sample automation system including a second needle driver including a second sample needle configured to add a volume of reagent to the sample vial. 一种液相色谱系统包括溶剂递送系统；包括与溶剂递送系统流体连通的样品递送系统的样
