美国标准局最近公布用于校核分光光度计光度标度的固体和液体标准参考材料。为了检定和校核这些标准参考材料,已研制一台专门的高准确度分光光度计,安装在盖茨堡美国标准局分析化学处。在美国标准局发起召开的关于分光光度 The U.S. Bureau of Standards recently published solid and liquid standard reference materials for the calibration of spectrophotometer luminosity scales. In order to test and verify these standard reference materials, a specialized high-accuracy spectrophotometer has been developed and installed at the Analytical Chemistry Division at the U.S. Bureau of Standards in Gettysburg. In the United States Bureau of Standards initiated a meeting on spectrophotometry
