According to the United States Pharmacopeia and the National Formulary (USP 40-NF 35*), analysis of alanine and aspartic acid, and their related compounds (organic acids) should be carried out with a column with L17 packing material and meets following requirements. The SUGAR SH1011 confirmed the requirements were met.
(Note) Alanine nor aspartic acid will not be detected in this method.
*The version at the time of the application acquisition.
