WAYEAL LC3600 Series Ultra-High-Performance Liquid Chromatograph

Overview

The WAYEAL LC3600 Series Ultra-High-Performance Liquid Chromatograph (UHPLC) is an engineered analytical platform designed to meet the rigorous demands of modern separation science in pharmaceutical, biotechnological, environmental, and academic laboratories. Built upon core UHPLC principles—namely high-pressure liquid delivery (≤150 MPa), sub-2 µm particle-packed column compatibility, and minimized system dispersion—the LC3600 delivers enhanced chromatographic resolution, reduced analysis time, and improved detection sensitivity relative to conventional HPLC systems. Its modular architecture supports seamless integration of multiple detector types and advanced sample handling modules, enabling method scalability from research-grade development to regulated QC workflows. The system operates under fundamental chromatographic theory: analyte partitioning between a mobile phase (gradient or isocratic) and a stationary phase within a high-efficiency packed column, with separation governed by thermodynamic affinity and kinetic mass transfer parameters.

Key Features

• Ultra-high-pressure binary solvent delivery system with linear motor-driven pumps, rated to 150 MPa (21,750 psi), supporting flow rates from 0.001 to 2.000 mL/min with ≤0.07% RSD flow precision (measured at 1 mL/min, water/methanol 1:1)
• “Needle-in-Flow-Path” autosampler design ensures continuous high-pressure needle flushing, minimizing carryover (<0.005%) and eliminating mechanical valve-induced dead volume
• Coolable sample compartment (4–40 °C, ±0.5 °C stability) for thermal preservation of thermolabile compounds, including peptides, oligonucleotides, and unstable metabolites
• Column oven with active pre-heating capability and rapid thermal equilibration (<3 min to setpoint), reducing baseline drift during fast gradients and improving retention time reproducibility
• Diode Array Detector (DAD) incorporating liquid-core waveguide flow cell technology, delivering near-lossless optical transmission and optimized pathlength efficiency across 188–900 nm
• Integrated degassing module with six-channel online vacuum degas, real-time leak detection circuitry, electrically actuated purge valves, and programmable solvent selection logic

Sample Compatibility & Compliance

The LC3600 Series accommodates a broad range of sample matrices—including small-molecule APIs, chiral compounds, natural product extracts, polymer additives, and polar ionic species—when paired with appropriate column chemistries (e.g., C18, HILIC, phenyl-hexyl, or SEC). Its hardware and firmware architecture support compliance with internationally recognized quality frameworks: instrument control software provides audit trail functionality, electronic signatures, and user-access-level management aligned with FDA 21 CFR Part 11 requirements. System suitability testing (SST) protocols, peak symmetry assessment, and tailing factor calculations are natively supported. Method validation documentation adheres to ICH Q2(R2) guidelines, while hardware performance verification follows ASTM E2893-22 (Standard Guide for UHPLC System Performance Testing).

Software & Data Management

Control and data acquisition are managed via WAYEAL ChromNav UHPLC Software—a Windows-based platform compliant with GLP/GMP environments. The software features sequence scheduling, real-time pressure/flow monitoring, gradient editor with dwell volume compensation, and automated calibration routines for detector wavelength accuracy and photometric linearity. Raw data files conform to ANDI/NetCDF format for long-term archival and third-party processing interoperability. All processing events—including integration parameter changes, baseline correction, and peak identification—are timestamped and logged with operator ID, satisfying traceability mandates. Optional network deployment enables centralized instrument monitoring across multi-user laboratory networks with role-based permissions.

Applications

The LC3600 Series is routinely deployed in: stability-indicating assay development for biologics and small molecules; impurity profiling per ICH Q3B(R3); residual solvent quantitation (ICH Q3C); dissolution testing per USP ; pesticide residue screening in food matrices (AOAC 2007.01); and metabolite identification workflows coupled with mass spectrometry. Its low dwell volume (<100 µL), high-pressure tolerance, and detector speed (up to 100 Hz spectral acquisition) make it especially suited for comprehensive two-dimensional liquid chromatography (LC×LC) and ultrafast gradient methods requiring sub-minute runtimes.

FAQ
