Advion Interchim Scientific puriFlash 535-XL Preparative Liquid Chromatography System

Overview

The Advion Interchim Scientific puriFlash 535-XL is a modular, medium-pressure preparative liquid chromatography (PLC) system engineered for reproducible, scalable purification of organic small molecules, natural products, peptides, oligonucleotides, proteins, biologics, and metabolites. Built upon the puriFlash Ultra Performance Flash Purification™ platform, it operates under controlled laminar flow conditions governed by Darcy’s law and optimized solvent delivery dynamics. Unlike analytical HPLC systems, the 535-XL is designed for fraction collection at milligram-to-gram scale with high recovery yield and minimal band broadening—critical for downstream structural characterization, biological assay, or regulatory submission batches. Its pressure rating of 35 bar supports both standard flash silica columns (e.g., F0012–F3000 series) and larger-diameter disposable or reusable DAC (Dynamic Axial Compression) columns, enabling method translation from discovery to early development without re-optimization.

Key Features

• Four-channel quaternary gradient pump with automatic solvent degassing and real-time flow/pressure monitoring
• 15-inch high-resolution capacitive touchscreen interface integrated with InterSoft X Genius software—supporting drag-and-drop gradient editing, method cloning, and KISS (Keep It Simple & Smart) workflow logic
• UV/Vis detection across 200–800 nm via extended-range photodiode array (PDA), enabling simultaneous multi-wavelength monitoring and peak purity assessment using spectral overlay algorithms
• Automated sample introduction via Load&Go technology: compatible with both liquid injection (loop-based) and dry-load (solid-phase) modes; supports direct loading of crude reaction mixtures onto pre-packed cartridges
• Modular architecture with field-upgradable components—including independent column holder, pre-column bracket, solvent management unit, and optional RFID-enabled consumable tracking
• Integrated fraction collector with dual rack support (112 × 18 × 150 mm tubes standard), programmable trigger logic (UV threshold, time, volume), and leak-detection–activated waste diversion

Sample Compatibility & Compliance

The puriFlash 535-XL accommodates diverse sample matrices including polar/nonpolar organics, acid/base-labile compounds, thermally sensitive biomolecules, and viscous crude extracts. Column compatibility spans standard flash cartridges (4–330 g), stainless-steel or glass DAC columns (up to 110 mm ID), and custom-packed beds. All hardware and software modules comply with Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) documentation requirements. InterSoft X Genius supports audit-trail logging per FDA 21 CFR Part 11, including user authentication, electronic signatures, and immutable method/version history. System validation packages align with ASTM E2500-13 and ISO/IEC 17025:2017 for analytical instrument qualification.

Software & Data Management

InterSoft X Genius provides a unified environment for method development, execution, and post-run analysis. Its intelligent method development assistant recommends initial gradient slopes and flow rates based on compound logP, molecular weight, and stationary phase chemistry. Raw chromatograms are stored in vendor-neutral .cdf format; spectral data are exportable as ASCII or .csv for third-party chemometric analysis (e.g., PCA, MCR-ALS). The software includes built-in tools for baseline correction, peak integration (tangent skim, valley-to-valley), retention time alignment, and purity heatmaps. Remote operation is supported via Ethernet (RJ45) or USB-C host connection, with secure HTTPS-based web interface for off-site monitoring.

Applications

• Purification of synthetic intermediates and final APIs in medicinal chemistry workflows
• Isolation of bioactive constituents from plant extracts and fermentation broths
• Desalting and buffer exchange of peptides and oligonucleotides prior to MS or NMR analysis
• Preparative separation of diastereomers and regioisomers under normal- and reversed-phase conditions
• Trace enrichment of low-abundance metabolites from biological fluids (plasma, urine, tissue homogenates)
• Supporting ICH Q5A/Q5B guidelines for impurity profiling and host-cell protein removal in bioprocess development

FAQ

What column formats are supported by the puriFlash 535-XL?
Standard flash cartridges (F0012–F3000), stainless-steel or glass DAC columns (up to 110 mm internal diameter), and custom-packed columns with compatible fittings.
Can the system be validated for GMP environments?
Yes—InterSoft X Genius includes 21 CFR Part 11-compliant audit trails, electronic signatures, and IQ/OQ documentation templates aligned with ASTM E2500-13.
Is method transfer possible from other puriFlash models?
Yes—gradient scaling, flow rate normalization, and column dimension compensation algorithms ensure seamless translation between puriFlash XS 520Plus, 5.050, 5.020, 5.015-XL, and 535-XL platforms.
Does the UV detector support real-time spectral deconvolution?
No—the PDA detector acquires full spectra at user-defined acquisition rates (0.1–10 Hz) but does not perform on-the-fly multivariate curve resolution; post-acquisition analysis requires external software.
What maintenance protocols are recommended for long-term reliability?
Daily solvent line flushing, quarterly pump seal inspection, semiannual lamp intensity calibration, and annual preventative service including valve actuation testing and detector wavelength verification per NIST-traceable standards.
