LC98IABB Amino Acid Analyzer
Product Overview
The LC98IABB Amino Acid Analyzer is a high-performance HPLC-based amino acid analysis system designed for precise detection of amino acids in feed, food, pharmaceutical, chemical, and biological samples. It uses a pre-column derivatization method and supports the analysis of 18 or 21 amino acids, providing excellent sensitivity, stability, and reproducibility.
This system can also function as a dual-purpose binary HPLC system, making it a flexible solution for advanced laboratory chromatography applications.

Key Features & Advantages
• Supports 18 or 21 amino acids analysis via pre-column derivatization
• Can operate as a binary gradient HPLC system
• High-precision P98-I binary gradient infusion pump system
• Imported motor drive with 20,000-step subdivision for ultra-smooth operation
• High-pressure capability up to 42 MPa (420 Kgf/cm²)
• Automatic program memory and method recall
• Intelligent safety control with pressure limit alarm and automatic shutdown
• Imported pulsation damper for stable baseline and minimal ripple
• UV98-I variable wavelength detector with high sensitivity
• Fully integrated LCD touchscreen interface with vertical chassis design
• Automatic wavelength scanning and zero adjustment
• Long-life deuterium lamp control system (up to 2500 hours lifespan)
• Patented flow cell design prevents bubble interference

Working Principle
The LC98IABB Amino Acid Analyzer operates based on High-Performance Liquid Chromatography (HPLC) combined with UV detection after pre-column derivatization.
• Amino acids in the sample are chemically derivatized before injection.
• The sample is injected into the binary gradient HPLC pump system.
• Compounds are separated based on their interaction with the chromatographic column.
• The UV detector (190–700nm) measures absorbance of each separated amino acid.
• A chromatogram is generated for qualitative and quantitative analysis.
This method ensures high resolution, strong selectivity, and accurate amino acid quantification.
