Abstract
An autosampler for a chromatograph includes a first injection port through which a sample is injected into a first analysis flow path of the chromatograph, a second injection port through which a sample is injected into a second analysis flow path of the chromatograph, a needle that is movable to both of the first injection port and the second injection port, and injects a sample into the first injection port and the second injection port, a first sample loop that stores a sample to be injected into the first analysis flow path, a second sample loop that stores a sample to be injected into the second analysis flow path, and a metering pump that loads a sample in the first sample loop and the second sample loop.
