How to recommend automatic analyzers and need for maintenance

摘要

It is determined whether an automatic analysis device is in a state where it is necessary to perform periodic cleaning or periodic replacement on a B/F separation passage of a reaction liquid suction nozzle 120 for B/F separation or the like and a detection passage of a reaction liquid suction nozzle 123 for detection, a detection unit 124, and the like, based on the properties of a specimen, a reagent, and a reaction liquid which is obtained by reacting the specimen and the reagent, an analysis protocol which defines treatment conditions of these solutions, and the number of times of dispensing, feeding, and measuring the solutions; and the determined result is displayed on a display 130 as a signal. Accordingly, the automatic analysis device is provided so as to be able to perform adequate maintenance in accordance with analysis conditions.
