Abstract

The present invention relates to an automatic chemistry analyzer comprising a reaction disk assembly (1), a sample and reagent disk assembly (2), a probe assembly (3) and a stirring assembly (4). A single probe (5) is used to dispense both the reagent and the sample into the reaction vessels. A pre-heating device disposed in the mechanical arm (6) for supporting the probe (5) pre-heats the reagent sucked into the probe to an appropriate temperature. The reaction vessels are disposable and may be replaced manually. The automatic chemistry analyzer may run single-reagent tests or double-reagent tests. According to the automatic chemistry analyzer of the present invention, the interval between injecting the first reagent of a test and injecting the sample of the same test may be 5.5 operation periods so that the first reagent in the reaction vessel may be maintained at or near an appropriate reaction temperature (37.degree. C.). In a process of running a double-reagent test, the incubation time between injecting the sample and injecting the second reagent is set freely by the operator according to the requirements of the test. The automatic chemistry analyzer and the analyzing method according to the present invention may improve the test correctness.
