Classification: LC Liquid Phase Morphology Processing Unit
Product Overview
The LC Liquid Phase Morphology Processing Unit is designed for advanced atomic fluorescence speciation analysis, enabling fully automated, coordinated control of the chromatographic pump, digestion system, vapor generation, and detection system. It allows precise analysis of different chemical forms (species) of elements such as arsenic (As), selenium (Se), mercury (Hg), and antimony (Sb), delivering high-performance speciation capabilities for research and analytical laboratories.
Key Features
- Built-in imported chromatographic column with temperature control function
- High-precision column temperature control (±0.01°C) with real-time display, setting, and adjustment for improved stability
- Integrated LC–AFS hybrid chemical reaction system with built-in UV digestion device and column oven
- Advanced on-line UV digestion system with sealed design to prevent UV leakage and ensure operator safety
- Dual-mode UV digestion (UV / non-UV) controlled via dedicated flow-path switching valve for convenient operation without pipeline replacement
- Built-in dual high-pressure micro infusion pumps with excellent stability (RSD < 0.02% at 1 mL/min)
- Supports isocratic or gradient elution depending on sample requirements
- Reserved interface for liquid chromatography autosampler integration, compatible with both imported and domestic autosamplers
- Seamless compatibility with Haiguang AFS atomic fluorescence spectrometers, enabling upgrade to LC-AFS combined system
- Highly integrated design combining high-pressure pump, injection system, UV digestion, column oven, and vapor generation system in one unit
- Enables dual-mode operation: total element screening followed by speciation analysis (“screen first, then speciate”) on a single platform
- One-key switching between total analysis and speciation analysis without manual tubing replacement
- Unified software system enabling coordinated control of atomic fluorescence detection and reverse control of the high-pressure pump
Application Advantage
Provides a complete, integrated solution for elemental speciation analysis, significantly improving efficiency, reducing manual operation, and enhancing analytical accuracy in complex sample testing environments.
