Abstract
The present invention provides a highly versatile method for amino acid analysis, the method enabling separation and analysis of amino acids in a sample with high precision in a shorter time. This method is a method for amino acid analysis, the method including a step of allowing a sample containing a plurality of amino acids to flow together with an eluentthrough a separation columnpacked with a cation exchange resin, thereby separating the amino acids, and a step of detecting the separated amino acids, wherein the eluentis an eluent containing a divalent or higher inorganic acid, a cation source, and water, and having a pH of 5.0 or lower, and the sample is allowed to flow through the separation columnheated by applying a temperature gradient including a temperature region of 100° C. or higher.
