Ezfaast Amino Acid Analysis of Protein Hydrolysates by LC-MS Kits

The EZ:faast amino acid analysis procedure consists of a solid phase extraction step followed by a derivatization and a liquid/liquid extraction; derivatized samples are quickly analyzed by liquid chromatography-mass spectrometry. The solid phase extraction is performed via a sorbent packed tip that binds amino acids while allowing interfering compounds to flow through . Amino acids on sorbent are then extruded into the sample vial and quickly derivatized with reagent at room temperature in aqueous solution. Derivatized amino acids concomitantly migrate to the organic layer for additional separation from interfering compounds. Organic layer is then removed, evaporated, and re-dissolved in aqueous mobile phase and analyzed on a LC-MS system. Total sample preparation time takes around 8 minutes and analysis is performed in around 12 minutes for a total start-to-finish time of around 20 minutes.
