High Performance Liquid Chromatography

High Performance Liquid Chromatography System BK-1800HPLC

Model BK-1800HPLC

Liquid chromatography is a technique that uses a liquid as the mobile phase to separate mixtures through a stationary phase. It utilizes the differences in partition coefficients and adsorption capacities of various components between the two phases, achieves separation through repeated distribution equilibrium, and combines with detectors for qualitative and quantitative analysis.

About this equipment

Features:

1. The system offers a comprehensive and flexible isocratic mode, and also provides binary gradient and quaternary gradient systems. Detection capabilities include PDA, UV/VIS, FL, RI and ELS.

2. The new optional, solvent manager units can easily switch 4 to 8 kinds of solvent base on binary gradient system. There are several configurations available for user selection.

3. The real-time solvent pressure compensation control enhances detection precision. The integrated check valve ensures stable fluid delivery and simplifies maintenance.
