Horn Point Laboratory Analytical Services

Horn Point Laboratory’s Analytical Services department utilizes the applied chemistry technique of high-performance liquid chromatography (HPLC) to separate and identify algal pigments, and quantify their concentrations within marine, estuarine, and lacustrine water samples. HPLC pigment data are useful in identifying phytoplankton species present in a water body, including harmful algal blooms. Horn Point has been assisting clients worldwide with their HPLC analysis needs for more than two decades.  Please request more information, including pricing, here.
