在用全自动生化分析仪性能测试分析

The analysis on performance of the full-automatic biochemical analyzer

目的通过对在用全自动生化分析仪进行主要指标的性能测试,结合设备使用和维护等方面的调研情况,分析使用维护过程中影响设备性能的因素和测试指标选择的合理性。方法依据行业标准的要求和试验方法进行检测。结果 3台生化分析仪中A、C全部符合所选指标的测试要求,B在3项指标中有2项不符合要求。结论在设备的计量、维护保养、消耗性部件更换、清洗液配套等情况相同的情况下,设备的生产和使用年限以及设备的开机频次和日常维护频次对吸光度稳定性和重复性影响较大,对样品携带污染率没有显著影响。本次测试和所选测试指标能够反映在用全自动生化分析仪的使用和维护情况对性能的影响,达到了客观评价在用全自动生化分析仪性能的目的。

Objective To analyze the possible factors affecting device performance in maintenance process and rationality of test indicators through using automatic biochemical analyzer combined with the use and maintenance of the equipment .Methods Based on the standard and test methods in industry standards ,the indicators were tested .Results In three automatic biochemical analyz‐ers ,A and C were in compliance with all the test requirements of the selected indicators ,while of the requirements of three indica‐tors ,two of B didn′t meet the requirements .Conclusion Under the same situation of the metering equipment ,maintenance ,the re‐placement of maintenance consumable parts and the composition of cleaning fluid ,the age and service life of the equipment ,the times of booting as well as the frequency of routine maintenance which would not affect the sample carryover could influence the stability and repeatability of absorbance greatly .The selected measurement indicators could reflect the impact of the condition of use and ma‐intenance on the performance of the automatic chemistry analyzer and evaluate the performance of automatic biochemical analyzer objectively .
