HPLC Method for Analysis of L-Lysine and L-Arginine

L-Lysine, an essential amino acid, supports growth, tissue repair, and helps alleviate anxiety. It is commonly found in red meats, beans, fish, and dairy products. L-Arginine, another essential amino acid, is used to treat congestive heart failure, fatigue, and circulatory diseases while also boosting the immune system. These compounds can be retained and separated on the Zodiac HST TH reverse-phase column, which features embedded ionic groups. The method is UV-compatible and serves as a general approach for analyzing similar compounds.
