Abstract

The invention provides a sample analyzing device which aims at solving the problem that the prior art can not consider both cost and constant speed test of a single-double reagent project. The device comprises a reaction disc, a sample / reagent disc and a sampling pin. The reaction disc has at least three stoppages and three rotations in each working period; the number of respective rotated cup sizes of three rotations is fixed after the integral number of rotated rings is removed; and the accumulated rotated ring number R is plus or minus one cup size (R is more than or equal to 1). Accordingto requirements, a sample vessel or a reagent vessel rotates to a sample / reagent absorption position through the sample / reagent disc in each working period. According to requirements, the sampling pin carries out the addition of a sample action sequence, a first reagent action sequence and a second reagent action sequence in different periods respectively, wherein sample exhaust action, first reagent exhaust action and second reagent exhaust action are completed in different stopping periods of the reaction disc respectively. The invention also provides a method for analyzing a sample.

Description

technical field [0001] The present invention relates to the field of detection and analysis of samples, in particular to a sample analysis device and a sample analysis method.
