Problems solved by technology

PITC method and AQC method require manual derivation, complicated operation, poor durability of chromatographic conditions, mobile phase adjustment almost every time, and some amino acids are poorly separated; OPA/FMOC method can be automatically derivatized, but mobile phase preparation is complicated, and some The separation of amino acids is not good, especially histidine and glycine. After several samples of the chromatographic column, the resolution is less than 1.0, and the life of the chr
