Isolera™ One Preparative Liquid Chromatography System by Biotage

Overview

The Isolera™ One is a medium-pressure, single-channel preparative liquid chromatography (PLC) system engineered by Biotage — a Swedish innovator and pioneer in flash and preparative chromatography since the 1980s. Designed explicitly for synthetic organic chemistry laboratories, natural product isolation, and medicinal chemistry workflows, the Isolera™ One implements a robust, scalable separation architecture based on gradient elution principles under controlled pressure and flow conditions. Unlike analytical HPLC systems, it operates at moderate pressures (up to 200 psi), optimizing balance between resolution, speed, and column lifetime for gram-scale purification. Its core function is rapid compound isolation from complex reaction mixtures or crude extracts without requiring method transfer between instruments — enabling direct scale-up from scouting to intermediate purification.

Key Features

• Intuitive touchscreen interface with real-time method editing: adjust gradient profiles (via point-and-drag graphical editor), flow rate, collection volume, UV detection wavelength, and fraction-trigger logic during active runs.
• Binary gradient pump with integrated tertiary solvent addition module: enables constant-ratio injection of a third modifier (e.g., acid, base, or ion-pairing agent) into the primary binary mobile phase — critical for maintaining solubility of polar or zwitterionic compounds and preventing column clogging or system overpressure.
• UV-Vis diode array detection (DAD) across 200–400 nm with λ-All spectral acquisition: captures full UV spectra for every eluting peak, supporting real-time peak identification, purity assessment, and spectral deconvolution without post-run analysis.
• Advanced baseline correction algorithms: dynamically compensate for solvent front shifts and gradient-induced absorbance drift, minimizing false triggers and reducing unnecessary solvent consumption by up to 60% compared to fixed-threshold fractionation.
• Modular hardware design: supports optional expansion with additional rack modules for high-capacity fraction collection (up to 9.6 L total volume), and seamless integration with Biotage’s full range of silica- and reversed-phase-packed columns (SNAP, SNAP Ultra, ZIP, ZIP Sphere; 5 g – 750 g).
• TLC-to-Step Gradient translation tool: converts R_f values from thin-layer chromatography plates into optimized step-gradient methods, accelerating method development for new compounds.

Sample Compatibility & Compliance

The Isolera™ One accommodates a broad spectrum of sample types including small-molecule organics, heterocycles, peptides, and natural product isolates. It is fully compatible with both normal-phase (silica-based) and reversed-phase (C18, C8, diol) media, supporting standard flash, gradient flash, and semi-preparative applications. All hardware components comply with CE marking requirements for electromagnetic compatibility (EMC) and low-voltage directive (LVD). The system supports GLP-compliant data integrity when operated with Isolera Spektra software configured for audit trail logging, electronic signatures, and user-access controls — aligning with FDA 21 CFR Part 11 expectations for regulated environments where traceability and method reproducibility are essential.

Software & Data Management

Controlled exclusively via Biotage Isolera Spektra software, the Isolera™ One delivers enterprise-grade chromatographic data handling. Spektra provides native support for method export/import, spectral library matching (via embedded reference spectra), 2D/3D chromatogram visualization, and automated purity calculation using peak area ratios across multiple wavelengths. Raw data files (.spc) are stored in vendor-neutral formats suitable for long-term archival and third-party reprocessing. Software licensing includes remote desktop control, allowing method setup and monitoring from office workstations — eliminating the need for dedicated instrument PCs in fume hoods or gloveboxes. Audit trails record all parameter changes, run starts/stops, and fraction collection events with timestamped user attribution.

Applications

• Rapid purification of reaction mixtures following cross-coupling, amidation, or cyclization reactions.
• Isolation of bioactive constituents from plant extracts or fermentation broths.
• Preparative-scale separation of regioisomers and diastereomers using optimized gradient and modifier strategies.
• Method scouting and scalability studies — identical methods developed on Isolera™ One can be directly transferred to higher-capacity Isolera LS or Horizon systems without re-optimization.
• Support for quality control in early-stage drug discovery, where compound identity and purity must be confirmed prior to biological testing.

FAQ

What column formats are supported?
Biotage SNAP, SNAP Ultra, ZIP, and ZIP Sphere cartridges (5 g to 750 g); larger formats (up to 1500 g) require the Isolera LS platform.
Does the system support method validation per ICH guidelines?
While not a GMP-certified instrument, its software and hardware architecture enable documentation practices consistent with ICH Q2(R2) for method verification in non-GMP research settings.
Can UV spectra be exported for external spectral database matching?
Yes — full-scan DAD data (.spc) exports include wavelength, absorbance, and retention time metadata compatible with commercial spectral search engines.
Is remote operation secure over institutional networks?
Spektra software supports encrypted remote desktop sessions via standard Windows RDP protocols; network configuration follows IT department security policies.
What maintenance is required for long-term reliability?
Routine checks include pump seal inspection every 6 months, UV lamp replacement every 2,000 hours, and annual calibration verification using certified standards.
