方案详情：
Atmospheric water vapor and carbon dioxide (CO2) strongly absorb in the infrared region and can interfere with the analysis and detection of weak sample peaks due to the additional peaks in the spectrum. In order to reduce the effect of the background peaks associated with H20 and CO2 it is important to maintain the concentration of water vapor and CO2 at the same level when measuring both the background and sample. In this application note, we would like to introduce a couple measurement options to minimize the effects of CO2 and water vapor, including “Shuttle Measurement” and “Purge and Vacuum”.

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.
