This Standard Reference Material (SRM®) is intended primarily for use in calibration of chromatographic instrumentation for the determination of amino acids. NIST-2389a is a solution of 17 amino acids in a 0.1 mol/L aqueous solution of hydrochloric acid. A unit of NIST-2389a consists of five 2-mL ampoules each containing approximately 1.2 mL of the solution under argon. /// Sample value(s) - please ask for current certificate.
