Automatic analysis apparatus

摘要

An automatic analysis apparatus, in which analysis results of immunoassay analysis items are not influenced by carry-overs between samples even when the same sample container is conveyed both to a biochemical analysis unit (104) and an immunoassay analysis unit (103) to permit sample dispensing. The immunoassay and biochemical analysis units are arranged along a rack conveyor (102). A carry-over avoidance level is set on a screen every analysis item before start of an analyzing operation. When a sample given an instruction to analyze only analysis items having low carry-over avoidance levels is to be dispensed in the biochemical analysis unit (104), a dispenser nozzle (401) is subjected to ordinary cleaning by water. When a sample given an instruction to analyze analysis items having high carry-over avoidance levels is to be dispensed in the biochemical analysis unit (104), a dispenser nozzle (401) is cleaned with a detergent solution and water.
