✦ Synopsis

The shadowgraph method is used to visualize mobile phase flow through a liquid chromatography absorbance cell with "Z" flow geometry . It is shown that mixing is incomplete in the cell . Composition gradients persist throughout the elution of any sample . The gradients systematically change as the sample flows through the cell . Additionally, window wedge angles are measured in several cells . The implications for low noise absorbance detectors are discussed .
