Agela FLEXA HP1000 High-Flow Preparative Liquid Chromatography System

Overview

The Agela FLEXA HP1000 is a high-flow, modular preparative liquid chromatography system engineered for laboratory-scale purification of small- to medium-molecule compounds—including natural products, synthetic intermediates, pharmaceutical actives, and chiral molecules. Built on a high-pressure LC architecture, it operates under isocratic or gradient elution modes with precise solvent delivery up to 10 MPa (100 bar), enabling robust separation on both reversed-phase (C18, C8) and normal-phase (silica, amino) columns. Its core fluidic design incorporates cam-profile flow compensation technology to minimize pulsation-induced baseline noise—critical for reliable peak integration during collection-triggered fractionation. The system’s open architecture supports seamless integration of third-party detectors (e.g., ELSD, MS interfaces) and conforms to fundamental chromatographic principles defined in ISO 17025-accredited laboratories.

Key Features

• High-Capacity Dual-Piston Pump: Delivers stable flow from 0.1 to 1000 mL/min with ±3% accuracy across the full range; employs multi-point flow calibration curves and cam-driven motion control to ensure reproducible gradient formation and low pulsation (<0.5% RSD).
• Chemically Resilient Fluid Path: Features floating plunger seals and solvent-compatible fluoropolymer/elastomer sealing materials, validated for compatibility with acetonitrile, methanol, THF, dichloromethane, hexane, and isopropanol—enabling method transfer between reversed- and normal-phase conditions without hardware modification.
• Dual-Wavelength UV/Vis Detector: Equipped with dual optical channels (190–800 nm) and real-time absorbance ratio monitoring; optimized for contamination resistance via bubble-trap geometry and flow-cell purge pathways—reducing downtime during extended purification runs.
• Modular Scalability: Supports plug-and-play expansion with optional modules: refrigerated auto-sampler (1–120 vials), timed or peak-triggered fraction collector (up to 168 tubes), multi-column switching valve (4-position), and optional mass-directed or conductivity-based trigger inputs.
• Robust Mechanical Architecture: All wetted parts are constructed from 316L stainless steel or PEEK; pump head and detector flow cells are pressure-rated to 10 MPa; system chassis meets IEC 61000-6-2 EMC immunity standards.

Sample Compatibility & Compliance

The FLEXA HP1000 accommodates sample loads ranging from milligram to multi-gram quantities per injection, depending on column dimensions (ID 20–100 mm) and stationary phase chemistry. It supports standard analytical-to-preparative method translation workflows per USP <621> and ICH Q5A guidelines. While not pre-certified for GMP environments, its audit-ready operation log—recording all method parameters, pressure traces, UV signals, and fraction events—facilitates GLP-compliant documentation. Data integrity aligns with ALCOA+ principles; raw chromatograms and event logs are stored in vendor-neutral .csv and .cdf formats compatible with LIMS and electronic lab notebook (ELN) platforms.

Software & Data Management

Controlled via Agela ChromoView Pro software (Windows 10/11, 64-bit), the system provides intuitive method building, real-time chromatogram overlay, and automated fraction collection logic (threshold-based, time-window, or peak-area gated). All acquisition and processing parameters—including wavelength selection, smoothing algorithms, baseline correction models, and retention time locking—are fully scriptable and exportable. Audit trails record user login/logout, method edits, and instrument state changes—supporting compliance with FDA 21 CFR Part 11 when deployed with Windows domain authentication and encrypted database storage.

Applications

• Purification of synthetic peptides and oligonucleotides prior to structural characterization (NMR, HRMS)
• Isolation of bioactive constituents from plant extracts and fermentation broths
• Chiral resolution of racemic APIs using polysaccharide-based preparative columns
• Desalting and buffer exchange of protein fragments in early-stage bioprocess development
• Method scouting and scale-up studies bridging analytical HPLC to pilot-scale purification

FAQ

What column dimensions are supported on the FLEXA HP1000?
Standard configurations accommodate columns with internal diameters from 20 mm to 100 mm and lengths up to 500 mm; custom flow-path adaptations are available for larger-bore or packed-bed reactors.
Can the system be integrated with a mass spectrometer for mass-directed collection?
Yes—via analog TTL or RS-232 output from external MS systems; ChromoView Pro accepts external trigger signals to initiate fraction collection based on m/z-selected peaks.
Is gradient delay volume characterized and compensatable?
Gradient dwell volume is measured per installation (typically 2.5–4.0 mL depending on mixer and detector cell volume); software allows manual offset adjustment to synchronize gradient onset with detection.
Does the system support remote monitoring or unattended overnight operation?
Full remote access is enabled via secure RDP or VNC over local network; run-time error handling includes automatic pump shutdown on overpressure, leak detection, and UV lamp failure—with email/SNMP alerts configurable through Windows Task Scheduler.
Are validation documents (IQ/OQ) available for this system?
Agela provides standardized IQ/OQ protocols aligned with ASTM E2500 and ISO/IEC 17025; site-specific execution requires qualified personnel and calibrated metrology equipment (pressure transducer, flowmeter, UV intensity meter).
