Abstract
An autosampler is provided with a needle, syringe pump, needle drive mechanism, sample loop, and flow path switching mechanism. The flow path switching mechanism has a plurality of solvent delivery flow paths that each deliver a different solvent, an analysis flow path that is in communication with an analysis column for separating a sample, and a plurality of connection ports to which the ends of the sample loop are individually connected, and switches, by switching the Connection state between the connection ports, to either a loading mode for connecting all the solvent delivery flow paths to the analysis flow path without interposing the sample loop or an injecting mode for interposing the sample loop between all the solvent delivery flow paths and the analysis flow path.
