方案详情：
An emission line of light source such as a sodium lamp or a mercury lamp is usually used to measure the optical rotation of pharmaceutical products. However, the Japanese Pharmacopeia and the European Pharmacopeia only mention the use of a sodium lamp as the light source. A polarimeter using a halogen lamp and a band pass filter (BPF) can also be used, as mentioned in the United States Pharmacopeia. However, the measurement error from the transmission property, that is the difference between the center wavelength of the BPF and the wavelength of emission line, cannot be avoided. Herein, the optical rotation of pirarubicin was measured using a sodium lamp and a halogen lamp, and the measurement error between the results was evaluated.

使用圆二色自动滴定装置分析人血清白蛋白与水杨酸相互作用
This application notes demonstrates the use of the J-1500 CD spectrometer and ATS-530 automatic titrator to monitor the interaction of HSA titrated with 3,5-diiodosalicylic acid. While 3,5-diiodosalicylic acid is achiral, its interaction with chiral HSA induces circular dichroism.
