For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
HPLC Separation of Amino Acids in Supplements Capsules
April 10, 2005

Glutamine, valine, isoleucine, and leucine are baseline resolved in a dietary supplement with a mobile phase of acetonitrile, water, and sulfuric acid with ultraviolet (UV) detection at 210 nm on a Primesep 100 column. Increasing the sulfuric acid concentration allows elution of arginine. Primesep 100 separates underivatized amino acids and amines by combining reversed-phase and ion-exchange mechanisms. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN), and sulfuric acid with ultraviolet (UV) detection at 210 nm.
