Its computerized control workstation simplifies experimental processes while supporting various fields, including pharmaceuticals, environmental protection, academia, chemical industry, and the food industry.

High-Pressure Pump:

• The integrated solvent management system expands from a binary gradient system with 2 mobile phases to a 4-mobile-phase setup, streamlining solvent replacement and system cleaning tasks.
• This binary high-pressure gradient system supports diverse sample analysis requirements, offering flexible control of mobile phases for precise system flushing and phase switching post-sample detection.
• Advanced features, including time-programmed chromatography workstation software, deliver enhanced ease and user convenience.

Auto-Sampler:

• The precise metering pump and different injection modes ensure long-term data stability and high injection accuracy.
• With a sample injection range from 0.1 to 1000 µL, the autosampler accommodates both small and large volume samples efficiently.
• Cross-contamination is minimized through the auto-cleaning needle system, while optional refrigeration (4-40°C) makes the system ideal for biological and medical sample handling.

UV-Vis Detector:

• The dual-wavelength UV-Vis detector enables simultaneous detection of different wavelengths, maximizing versatility in HPLC analysis.
• Featuring high-precision grating and long-life light sources, the system ensures superior accuracy and quick data acquisition, reducing transmission interference through direct analog-to-digital conversion.

Column Oven:

• The advanced column temperature control system and dual-column design accommodate various chromatography column specifications, offering high stability and precision.
• Overtemperature protection ensures safety during High Performance Liquid Chromatography analysis.

Chromatography Workstation:

• The HPLC workstation software offers full control of system components, data security with one-click backups, and modular design for easy operation and real-time status monitoring.

Fraction Collector:

• The compact design and precise bottle-cutting technology optimize the preparation of high-purity substances, reducing dead volume and collection errors, making it perfect for complex HPLC sample collection.

Favorable Expansibility:

• Optional autosampler, UV-Vis, fluorescence, differential detectors, and fraction collectors enhance the system’s adaptability for diverse sample needs.
