Overview
Amino acid analysis is widely used in fields such as food science and pharmaceutical manufacturing. The Nexera Amino Acid Analysis System employs post-column fluorescence derivatization with o-phthalaldehyde (OPA)/N-acetylcysteine and a high-sensitivity fluorescence detector to selectively and sensitively quantify amino acids in samples containing high levels of contaminants.

Product Name / Subtitle
Nexera Post-column Amino Acid Analysis System

Features

• Selective detection of amino acids: Based on Shimadzu's post-column reaction technology combined with a high-sensitivity fluorescence detector for selective quantitation.
• Reliable results regardless of operator skill: High injection precision across a wide volume range and a dedicated design to ensure reliable sample cooling.
• Ready-to-use special reagent kit: Provides reagents and guidance for mobile phase preparation (pH control is important for separation repeatability in amino acid analysis).
