PRE-2000 Preparative High-Performance Liquid Chromatography System

Overview

The PRE-2000 Preparative High-Performance Liquid Chromatography System is an industrial-grade, high-pressure chromatographic platform engineered for reproducible isolation and purification of target compounds at gram-to-hundred-gram scales. Based on the fundamental principles of reversed-phase, normal-phase, and ion-exchange chromatography, the system utilizes precise solvent delivery, high-resolution UV/Vis detection, and robust column management to achieve consistent separation performance across diverse compound classes—including small-molecule APIs, natural product isolates, chiral intermediates, and synthetic oligomers. Its modular architecture supports both single-pump isocratic operation and dual-pump gradient elution, enabling method scalability from analytical scouting to process-level purification. Designed for compliance-critical environments, the PRE-2000 meets mechanical and electronic requirements aligned with ISO 9001-certified manufacturing practices and supports integration into GLP/GMP workflows through audit-trail-ready software interfaces.

Key Features

• High-pressure dual-pump gradient system capable of delivering stable flow rates from 0.01 to 80.00 mL/min per pump, with total system range extending to 100 mL/min for large-bore column applications
• Integrated auto-cleaning pump head design minimizes seal wear and reduces downtime associated with buffer salt crystallization or viscous mobile phase residues
• UV/Vis detector with 190–800 nm spectral range, ±1 nm wavelength accuracy, and baseline noise ≤0.15 × 10⁻⁵ AU at 254 nm (1 sec time constant), ensuring reliable peak quantitation during fraction collection
• Real-time data acquisition at 100 Hz enables high-fidelity capture of narrow peaks in fast-gradient or high-flow separations
• Pressure rating up to 5000 psi (345 bar), compatible with columns packed with sub-10 µm particles and stainless-steel or PEEK-lined hardware for extended service life
• Front-panel touchscreen interface with preloaded method templates, password-protected user levels, and USB export for offline analysis

Sample Compatibility & Compliance

The PRE-2000 accommodates standard preparative column dimensions (10–50 mm ID, 100–250 mm length) and supports a broad range of stationary phases—including C18, C8, phenyl-hexyl, silica, amino, and chiral selectors—enabling purification of acidic, basic, zwitterionic, and thermally labile compounds. Mobile phase compatibility includes aqueous buffers (e.g., ammonium acetate, phosphate), organic modifiers (acetonitrile, methanol, isopropanol), and additives such as TFA or formic acid. The system complies with key regulatory expectations for equipment qualification: it supports IQ/OQ documentation packages, provides traceable calibration logs for flow and wavelength, and delivers electronic records suitable for FDA 21 CFR Part 11–aligned environments when paired with validated software modules. All wetted materials meet USP Class VI biocompatibility standards.

Software & Data Management

The PRE-2000 operates with ChromaControl Pro v3.x, a Windows-based control and acquisition suite supporting method development, sequence scheduling, real-time chromatogram overlay, and automated fraction triggering via UV threshold or time window logic. Data files are stored in vendor-neutral .cdf format (compatible with OpenChrom and Chromeleon), while audit trails record all parameter changes, user logins, and instrument events with timestamps and operator IDs. Optional modules include electronic signature support, report generation compliant with ASTM E2500-13, and direct interfacing with third-party fraction collectors (e.g., Gilson FC204, Teledyne ISCO Foxy R1) via RS-232 or Ethernet TCP/IP protocols.

Applications

• Purification of active pharmaceutical ingredients (APIs) and impurity reference standards per ICH Q5 and Q7 guidelines
• Isolation of natural product fractions from plant extracts or fermentation broths for structure–activity relationship (SAR) studies
• Chiral resolution of racemates using polysaccharide-based columns for asymmetric synthesis validation
• Desalting and buffer exchange of peptides and oligonucleotides prior to lyophilization or formulation
• Scale-up support for process analytical technology (PAT) initiatives, including method transfer from UHPLC to preparative HPLC

FAQ

What column formats are supported by the PRE-2000?
Standard stainless-steel or PEEK-packed preparative columns with 10–50 mm internal diameter and 100–250 mm length; compatible with guard cartridges and in-line filters.
Can the system be used for method development at analytical scale?
Yes—flow rate and pressure parameters are fully adjustable down to 0.01 mL/min, allowing direct translation of analytical methods to preparative conditions using retention time normalization and linear velocity scaling.
Is remote monitoring supported?
The system includes Ethernet connectivity and supports secure remote access via VNC or vendor-provided web dashboard (requires optional license).
How often does the pump require maintenance?
Under typical operating conditions (aqueous/organic gradients, 8 h/day), pump seals and check valves are rated for ≥6 months of continuous use; auto-cleaning cycles extend component lifetime by reducing particulate accumulation.
Does the UV detector support multi-wavelength acquisition?
Yes—the diode array detector acquires full spectra (190–800 nm) at 100 Hz and allows simultaneous monitoring at up to four user-defined wavelengths during a run.
