Separation of N-Nitro-L-arginine on Newcrom R1 HPLC column

N-Nitro-L-arginine can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.

HPLC Method for Analysis of L-Lysine and L-Arginine
l-Lysine , L-Arginine Chr_1106 L-Lysine is an essential amino acid required for growth and tissue repair, it can also help with anxiety. The amino acid is most often found in red meats,beans, fish, and dairy products. L-Arginine is an essential amino acid that is used to treat congestive heart failure, combat fatigue and circulatory diseases. It is also used to stimulate the immune system. Obelisc R is a reverse-phase column. It contains embedded ionic groups and can retain L-Lysine and L-Arginine. The method is UV compatible and can be used as a general approach for analyzing similar compounds.
