日立7600全自动生化分析仪碱性清洗液的研究应用

Research and application of alkaline washing solution for HITACHI 7600 automatic biochemical analyzer

目的自制日立7600全自动生化分析仪碱性清洗液替代原装清洗液,降低仪器运行成本。方法根据日立7600全自动生化分析仪清洗原理,结合原装Hialkali-D清洗液的特点自制碱性清洗液。同等条件下,将检测自制清洗液的精密度、准确性以及稳定性试验与原装清洗液进行对比分析。结果经生化项目检测,与原装清洗液相比,两者检验结果差异均无统计学意义(P>0.05),且相关性很好(r>95%)。结论自制清洗液可替代原装清洗液在日立全自动生化分析仪上的使用,其有效期长,稳定性好。

Objective To research the self-made alkaline washing solution of Hitachi 7600 automatic biochemical analyzer for replacing original washing solution to reduce operating cost. Methods According to the washing principles of Hitachi 7600 fully automatic biochemical analyzer and combined with the characteristic of original HI ALKALI-D washing solution, the alkaline washing solution was prepared. The accuracy, precision and stability of self-made washing solution were detected and compared with the original washing solution under the same condi- tions. Results The detection results of biochemical indexes showed no statistical difference between two kinds of washing solution（P〉0.05） with good correlation（r〉95%）. Conclusion The self-made washing solution can replace the original wash solution of Hitachi automatic biochemical analyzer with good stability and long period of validity.
