The detector operates on the principle of Beer-Lambert’s Law. As the mobile phase and eluted analytes pass through the flow cell, the optical system directs light of a specific wavelength through the cell. The sample absorbs a portion of this light, and the photosensors measure the difference in light intensity against a reference path to calculate absorbance (expressed in Absorbance Units, or AU). 2.
