The Elite AAK amino acid analysis system employs HPLC technology for high-precision analysis of amino acids in various complex matrices. After pre-column derivatization using DNFB (2,4-dinitrofluorobenzene) as the derivatizing reagent, high-performance liquid chromatography (HPLC) gradient separation and ultraviolet detection are performed, simultaneously analyzing 18 essential amino acids with baseline resolution achieved in all cases.
The Elite AAK Amino Acid Analyzer delivers rapid, accurate amino acid analysis with high sensitivity. For example, for aspartic acid, it achieves an analysis time of less than 40 minutes, a linear range spanning over three orders of magnitude, and a detection limit as low as ppb level.
The system includes a complete reagent kit with amino acid standards, derivatization agents, and buffer components for sample preparation. An accessory pack provides essential equipment for hydrolysis, filtration, and system maintenance.
The Elite AAK amino acid analysis system demonstrates excellent stability, with retention time relative standard deviation (RSD) ≤0.25% and peak area RSD ≤0.8% for 18 amino acids across 7 consecutive injections. The method exhibits high sensitivity, with a low detection limit of 7.44×10-¹² mol for aspartic acid. The Elite AAK amino acid analysis system can perfectly separate amino acids in pharmaceuticals and foods. (Image-74) (Image-75)
