A survey was made to determine the linearity and accuracy of ultraviolet and visible wavelength photometers used by laboratories in New York State. Two solutions each of high-purity potassium dichromate and cobalt ammonium sulfate were submitted for photometric performance studies. The majority of the participant spectrophotometer results showed good correlation with reference data. Broad half-band width (greater than 10 nm) photometers showed little deviation from linearity. Coefficients of variation for the models surveyed were 5-10%.
开展了一项调查，以确定纽约州各实验室使用的紫外和可见波长光度计的线性和准确性。提交了两种高纯度重铬酸钾溶液和硫酸钴铵溶液用于光度性能研究。大多数参与的分光光度计结果与参考数据显示出良好的相关性。宽半带宽（大于10纳米）的光度计线性偏差很小。所调查型号的变异系数为5%-10%。
