Benefits of UV-VIS Spectroscopy

UV-Vis spectroscopy is a valid stand-alone means to determine and quantify nutrients and other components. In some instances, USP standards specify UV-Vis testing. Further interferences are decreased to improve detection levels when a UV-Vis detector is used with high-performance liquid chromatography (HPLC) testing.

Identity and Concentration Testing with HPLC

High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid absorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out of the column.
