Abstract
A method for analyzing a plurality of amino acids in a fluid sample by a user is provided comprising the steps of introducing the sample into a buffer solution, passing the sample in the buffer solution through a separation column and setting a lithium ion concentration in the buffer to no more than 0.3 mols/L up to a time before β-aminoisobutyric acid (β-AiBA) is eluted.

An apparatus for analyzing a plurality of amino acids in a fluid sample by a user comprising:
- a container for supplying a buffer solution;
- a control valve for controlling a lithium ion concentration of said buffer solution;
- an auto sampler for supplying said fluid sample;
- a separation column for separating said plurality amino acids in said buffer fluid samples;
- a processor in communication with said control valve and said auto sampler;
- and
- an analysis program residing on said processor for causing said processor to perform the acts of:
- introducing said sample into a buffer solution;
- passing said sample in said buffer solution through a separation column;
- fixing a lithium ion concentration of said buffer within a time of eluting from Hylys to His;
- and
- displaying said analysis for said user.
