Waters Prep SFC 150 Mgm Supercritical Fluid Chromatography System

Overview

The Waters Prep SFC 150 Mgm is a high-throughput preparative supercritical fluid chromatography (SFC) system engineered for scalable purification of chiral and achiral compounds in pharmaceutical, biotechnology, fine chemical, and materials research laboratories. It leverages carbon dioxide (CO₂) as the primary mobile phase—typically modified with low-toxicity organic solvents such as methanol, ethanol, or isopropanol—to deliver rapid method development, efficient compound isolation, and reduced environmental impact compared to traditional normal-phase liquid chromatography (NPLC). Unlike conventional HPLC systems, the Prep SFC 150 Mgm achieves elevated flow rates (up to 150 mL/min) without proportional increases in backpressure, enabling use of wide-bore columns (19 mm and 30 mm i.d.) and significantly shortening cycle times while maintaining high resolution and peak capacity. Its thermodynamic and transport properties—low viscosity, high diffusivity, and tunable solvent strength via pressure/temperature modulation—make SFC particularly well-suited for purifying thermally labile, nonpolar, or moderately polar molecules that are challenging to resolve using reversed-phase or silica-based NPLC methods.

Key Features

• QGM Low-Pressure Quaternary Gradient Pump: Delivers precise, pulseless modifier solvent delivery at flow rates up to 150 mL/min with integrated degassing and solvent selection capability across four reservoirs.
• P200X High-Pressure CO₂ Pump: Dual-head stainless steel pump featuring sapphire-coated cam-driven pistons, self-priming check valves, real-time pressure feedback via embedded transducers, mass flow monitoring, brushless motor drive, and certified burst disc protection for safe operation at pressures up to 400 bar.
• Modifier Stream Injector: Enables discrete, air-gap–assisted injection of sample solutions using standard 2 mL loop and 5 mL syringe; air gaps act as physical spacers between solvent and analyte zones to minimize band broadening and dilution.
• Preparative Fraction Collector: Equipped with six programmable 2 L collection positions, retractable front access door, universal drain port compatible with standard lab waste manifolds, and removable spill tray for containment and compliance with laboratory safety protocols.
• Integrated Backpressure Regulator (BPR): Maintains stable supercritical phase conditions throughout the column and detector path via active pressure control, ensuring reproducible retention time and selectivity across runs.

Sample Compatibility & Compliance

The Prep SFC 150 Mgm supports purification of small-molecule APIs, synthetic intermediates, natural product extracts, catalyst ligands, and polymer additives. Its compatibility with both chiral stationary phases (e.g., cellulose- and amylose-derived columns) and achiral silica-based media enables broad application scope across early-stage discovery through late-stage process development. The system meets essential regulatory expectations for GxP environments: ChromScope 2.0 SFC software includes audit trail functionality compliant with FDA 21 CFR Part 11 requirements, electronic signature support, user role-based access control, and secure data archiving. All hardware components adhere to IEC 61010-1 safety standards, and CO₂ handling conforms to ASME B31.1 piping guidelines for high-pressure gas service. Routine operation requires no hazardous solvent storage or disposal infrastructure, aligning with ISO 14001 environmental management principles and reducing institutional EHS burden.

Software & Data Management

Control and method execution are managed exclusively through Waters ChromScope 2.0 SFC software, a native Windows 10 application designed specifically for preparative SFC workflows. The interface features drag-and-drop method building, real-time pressure/flow/temperature visualization, automated gradient programming, fraction-trigger logic based on UV absorbance or time windows, and seamless integration with Waters Empower CDS for cross-platform data review and reporting. Raw data files (.wiff) are stored in vendor-neutral formats supporting third-party reprocessing and long-term archival per ALCOA+ principles. Batch processing templates, method validation reports, and instrument performance qualification (IQ/OQ/PQ) documentation packages are available upon request to support GLP and GMP audits.

Applications

• Chiral resolution of enantiomers in asymmetric synthesis campaigns and API manufacturing.
• Rapid purification of reaction mixtures containing multiple byproducts with minimal solvent consumption.
• Isolation of unstable or oxidation-prone compounds under inert CO₂-rich environment.
• Scalable method transfer from analytical SFC to preparative scale without re-optimization.
• Green chemistry initiatives requiring >70% reduction in chlorinated or hexane-based solvent usage.
• Support for continuous manufacturing modules when integrated with inline concentration and crystallization units.

FAQ

What is the maximum operating pressure of the Prep SFC 150 Mgm system?

The system is rated for continuous operation up to 400 bar, with safety-critical components certified to ASME Section VIII standards.
Can the system be used for both analytical and preparative workflows?

While optimized for semi-preparative to preparative scale (10 mg to >10 g per run), it supports analytical method scouting using narrow-bore columns with flow splitting or low-flow configurations.
Does ChromScope 2.0 support remote monitoring or integration with LIMS?

Yes—via OPC UA protocol and configurable RESTful API endpoints for bidirectional data exchange with enterprise laboratory information management systems.
How does the system handle CO₂ supply and phase stability?

It accepts liquid CO₂ from bulk tanks or disposable cylinders; internal pre-heating and temperature-controlled tubing ensure consistent supercritical state entry into the pump head and column oven.
Is method transfer from other SFC platforms supported?

ChromScope 2.0 includes import tools for common method file formats (e.g., .sfc, .xml) and provides scaling calculators for column geometry and flow rate adjustments.
