Abstract

In injecting a sample sucked into a sample loop in an autosampler from an injection needle into an analytical flow path via an injection port by a mobile phase, a sending flow rate of the mobile phase is reduced from a certain flow rate determined in an analysis condition to reduce pressure applied on a joint section between the needle and the injection port to thereby reduce the sample remaining in the injection port.
