我院2002-05引进HITACHI7060全自动生化分析仪,工作中经过摸索和实践,总结了常见故障及其处理方法,介绍如下。1测定结果为零或负值1.1故障分析(1)试剂针(或样品针)不能检测到液面,造成空吸;(2)样品或试剂不足;(3)超出反应的线性范围;(4)光路中有阻挡物阻挡光线的通过。1.2排除 Our hospital introduced the HITACHI7060 automatic biochemical analyzer from 2002-05. Through the exploration and practice in the work, the common faults and their treatment methods are summarized as follows. 1 Determination of zero or negative results 1.1 Failure Analysis (1) reagent needle (or sample needle) can not detect the liquid surface, resulting in suction; (2) lack of samples or reagents; (3) beyond the linear range of the reaction; (4 There are barriers in the light path to block the passage of light. 1.2 exclusion
