石英比色皿配对误差对紫外可见分光光度计测量误差的影响

Influence of matching error of quartz cell pair on measurement error of UV spectrophotometer.

本文论述了石英比色皿配对误差的重要性;根据笔者的经验和教训,从仪器学理论和应用实践相结合的角度,讨论了石英比色皿的配对误差对紫外可见分光光度计分析误差的影响。用实验数据说明了用于双光束/准双光束/单光束的紫外可见分光度计的石英比色皿必须配对。供紫外可见分光光度计的研究者、设计者、生产者和使用者参考。

The importance of matching error of quartz cell pair is described. The influence of matching error on the measurement error of UV spectrophotometer is discussed from the point of instrument theory and practical applications. The experimental data show that only the quartz cell pair are correctly matched will the good analytical results be obtained.
