We evaluated the Technicon RA-1000 analyzer, with emphasis on its potential for user-defined method development. Optical linearity and sample pipetting linearity were good. The reagent pipetting system delivered slightly less than the nominal amount, owing to the volumetric effect of added mixing bubbles. Carryover of aqueous solutions was negligible. The instrument had good adaptability for user-defined methods and performed well in method comparisons. The observed dynamic range for enzymes (0-3000 U/L) was excellent. The worklisting software performed its intended functions well, but has limitations. We believe that the RA-1000 represents a significant contribution to the practice of clinical chemistry. A sophisticated benchtop machine, it includes several innovations, along with a few problems that are peculiar to its technology.
我们对Technicon RA - 1000分析仪进行了评估，重点在于其用户自定义方法开发的潜力。光学线性和样品加样线性良好。由于添加的混合气泡的体积效应，试剂加样系统的加样量略低于标称值。水溶液的携带污染可忽略不计。该仪器对用户自定义方法具有良好的适应性，在方法比较中表现良好。观察到的酶的动态范围（0 - 3000 U/L）极佳。工作列表软件能很好地实现其预期功能，但存在局限性。我们认为RA - 1000对临床化学实践做出了重大贡献。作为一台精密的台式仪器，它有多项创新之处，同时也存在一些因其技术特性而特有的问题。
