Abstract:
1. An analyzing device comprising: a feeder connected to a container in which a sample is contained, the feeder being configured to suck the sample from the container, hold an amount of the sample necessary for two or more measurements, and configured to feeding the sample to an injection valve with multiple ports; the feeder further comprise of a tubular portion directly connected to one of the multiple ports of the injection valve; a controller for performing control for feeding the sample from the feeder to a measurer; wherein, in measuring the sample, the controller performs control so that results of a plurality of measurements are obtained with respect to the single container in which the sample is contained, without changing the container; the measurer includes a column containing a filler and an injection valve with multiple ports, capable of introducing a predetermined amount of sample into the column and also capable of feeding a mobile phase into the column, the measurer being configured so that the sample adsorbed to the filler is desorbed by the mobile phase and an effluent thereby produced is subjected to measurement for obtaining measurement results; and in checking accuracy by using a sample of a known concentration as the sample, the controller performs control of the feeder and the measurer so that results of a plurality of measurements are obtained with respect to the single container in which the sample of the known concentration is contained, without changing the container.
