Abstract
A control method for an automatic analyzer that can improve robustness, throughput, and measurement accuracy. The automatic analyzer includes a sample loop connected between two sample ports of a plurality of sample ports of a switch valve. The method includes the steps of: adjusting a drive parameter of the syringe corresponding to a viscosity of the sample acquired in advance; switching the switch valve to a first state in which the sipper and the syringe contact with each other without through the sample loop; driving the syringe based on the drive parameter to draw and introduce the sample through the sipper; switching the switch valve to a second state in which the syringe and the sample loop conduct with each other; and driving the syringe based on the drive parameter to introduce the sample into the sample loop.
