High performance liquid chromatography analyzes the components of a sample by pumping a solution through a column containing an adsorbent material, which separates and interacts distinctly with the components. The flow rate is measured as the various components exit the column.

Beckman acquired HPLC manufacturer Altex Scientific, Inc. in 1978.
