Solutions of cobalt nitrate sealed in vials were circulated to all clinical chemistry laboratories in the United Kingdom. Participants reported wavelengths of maximum absorbance together with the actual absorbances obtained. The results were compared with values obtained from the National Physical Laboratory. The results show a wide scatter, and several instruments were extensively repaired or replaced as a result of the survey. The most recently marketed machines had the best performance, and it is suggested that regular quality control and maintenance of the machines is vital. It is intended to set up a scheme for regular monitoring of spectrophotometer performance.
密封在小瓶中的硝酸钴溶液被分发给英国所有临床化学实验室。参与者报告了最大吸光度的波长以及实际获得的吸光度。将结果与从国家物理实验室获得的值进行比较。结果显示出广泛的离散度，并且由于此次调查，有几台仪器进行了大规模维修或更换。最新上市的机器性能最佳，建议对机器进行定期质量控制和维护至关重要。计划建立一个定期监测分光光度计性能的方案。
