LC98IAAA Amino Acid Analyzer
Product Overview
The LC98IAAA Amino Acid Analyzer is a high-precision instrument designed for rapid and accurate analysis of amino acids in feed, food, pharmaceutical, and chemical samples. Equipped with a dual-gradient pump system, variable wavelength UV detector, and column temperature control, this analyzer supports pre-column derivatization methods capable of separating 18–21 amino acids with exceptional sensitivity.
Built for versatility, the LC98IAAA can also function as a binary high-performance liquid chromatography (HPLC) system, providing reliable performance in laboratory or industrial applications. Its configuration ensures high resolution, reproducibility, and low detection limits, ideal for routine analysis and research.

Key Features
•High Sensitivity Detection: Minimum detectable amount down to 2×10⁻⁸ g/mL, ensuring trace-level amino acid quantification.
•Wide Flow Range & Precision: Dual-gradient pump system allows 0.01–10 mL/min with accuracy <3 μL at low flow and <1% at high flow.
•UV Detection: Variable wavelength range 190–700 nm, wavelength accuracy ±1 nm, repeatability ±0.4 nm.
•Robust Chromatography: Dedicated ODS C18 5 μm, 4.6 × 250 mm amino acid column for optimal separation.
•Stable System Operation: Pressure range 0–42 MPa, low baseline noise (2.5×10⁻⁵ AU p-p), and minimal drift (1×10⁻³ AU/hr).
•Flexible Configuration: Optional pH meter and thermostatic water bath; protective column and derivatization kit included.
•User-Friendly Software: N2000 Chromatography Workstation for automated data acquisition, processing, and reporting.

Working Principle
The LC98IAAA Amino Acid Analyzer employs pre-column derivatization HPLC. Amino acids in the sample react with derivatization reagents to form detectable compounds before separation through the ODS C18 column.
Process Flow:
•Sample injection via Rheodyne 7725i valve.
•Dual-gradient pump delivers mobile phases with precise flow control.
•Derivatized amino acids separated on C18 column under controlled temperature.
•UV detection measures absorbance across 190–700 nm.
N2000 workstation processes chromatograms and quantifies amino acid concentrations. This method allows high-resolution separation of 18–21 amino acids, suitable for complex sample matrices in food, feed, and pharmaceutical testing.
