HPLC System Order Guide

Advanced quaternary gradient system with patented technologies for superior analytical performance

System Overview

High-precision quaternary HPLC with 10,000 psi pressure capability, patented mixing technology, and advanced pressure sensing. Features mechanical zero-reset technology for extended service life and ultra-low carryover (≤0.0005%). Ideal for trace-level detection in food safety, pharmaceuticals, and environmental analysis.

Patented Technologies Patent Protected

  • Proprietary Mixer Design: Internal channels with micro-pores for enhanced mixing efficiency
  • High-Pressure Flow-Through Sensor: >20,000 psi tolerance with rapid pressure feedback
  • Mechanical Zero-Reset: Impact force protection extending component service life
  • Optical Design: Aspheric mirror with fiber optic thermal management (PDA detector)
