FLOW INJECTION AUTOMATIC ANALYZER

摘要

PROBLEM TO BE SOLVED: To provide a flow injection automatic analyzer which enables efficient analysis of multiple kinds of samples even when a long time is required for one analysis while allowing analysis of various types simultaneously by using one sampler. SOLUTION: One sampler 1 is provided with a plurality of analysis systems A-D while selector valves 20A-20D and a carrier liquid supply path 25 are arranged for each of the analysis systems. The selector valves have two positions at which there are a path communicating with an effluent path 23 from a sample introduction path 21 and a path communicating with the analysis system from the carrier liquid supply path 25, any one of which forms one passage via a sample loop 22 to make communication with the effluent path 23 from the selector valve on the upstream side close to the sampler 1 or the sample introduction path 21 to the selector valve on the downstream side respectively among the plurality of selector valves.
