WebMar 26, 2024 · Circular dichroism (CD) is used to give information about the chirality or handedness of molecular systems. It is particularly widely applied to determine the secondary structure of proteins such as biopharmaceutical products. Introduction CD is used to give information about the chirality or handedness of molecular systems. WebSince circular dichroism (CD) is an absorption technique based on Beer’s Law, the sample concentration and pathlength are critical for obtaining good CD data. If a sample is too concentrated or the path length is too long, the sample will absorb too much light, and not enough will pass to the detector for a reliable CD signal to be acquired.
