CD Spectrometer

A CD (circular dichroism) spectrometer is a scientific instrument that measures how chiral molecules—those that are mirror images of each other—absorb polarized light differently. By passing circularly polarized light through a sample, it detects subtle differences in absorption, providing insights into the molecule’s overall three-dimensional structure, such as protein folding or secondary structure. This technique is valuable in biochemistry and molecular biology for understanding molecular conformations and stability, helping researchers study how biological molecules behave and interact in different conditions.
