Kromasil PREPHPLC Preparative High-Performance Liquid Chromatography System

Overview

The Kromasil PREPHPLC is a fully integrated preparative high-performance liquid chromatography (prep-HPLC) system engineered for scalable, reproducible, and robust purification of high-value compounds in research, process development, and early-stage manufacturing environments. Unlike analytical HPLC systems optimized for detection sensitivity, the PREPHPLC platform is purpose-built for separation throughput, column loading capacity, and operational stability under extended run conditions. It operates on the fundamental principle of differential partitioning—where analytes are resolved based on their relative affinity toward a stationary phase (e.g., silica-based Kromasil C18, phenyl-hexyl, or amino columns) and a mobile phase gradient under precisely controlled pressure, flow, and temperature regimes. Designed to meet the stringent demands of biopharmaceutical purification workflows, the system supports both isocratic and gradient elution modes with programmable solvent delivery, UV/Vis detection across 190–800 nm, and fraction collection synchronized to retention time or peak threshold.

Key Features

• Modular architecture supporting flow rates from 1 to 200 mL/min, compatible with column internal diameters ranging from 10 mm to 100 mm (ID), enabling seamless transition from lab-scale screening to pilot-scale purification.
• High-pressure binary or quaternary solvent delivery system with pulse-free pumping, flow accuracy ±0.5% RSD, and gradient composition precision ≤0.2% v/v.
• UV/Vis detector with dual-wavelength monitoring, 10 mm pathlength flow cell, and real-time spectral acquisition (up to 10 Hz) for peak purity assessment and co-elution detection.
• Automated fraction collector with programmable trigger logic (time-, volume-, or absorbance-based), 96-well plate or rack-based vial handling, and position tracking for full traceability.
• Stainless steel fluidic path compliant with USP Class VI materials; all wetted components resistant to common organic solvents (acetonitrile, methanol, THF) and aqueous buffers (pH 2–8).
• Integrated system control via Ethernet-connected PC running Kromasil PrepControl software—supporting method storage, audit trail logging, and user-level access control aligned with ALCOA+ data integrity principles.

Sample Compatibility & Compliance

The Kromasil PREPHPLC accommodates a broad spectrum of sample matrices, including synthetic small molecules (<500 Da), peptides (up to 5 kDa), oligonucleotides, natural product extracts, and monoclonal antibody fragments. Its design adheres to key regulatory expectations for purification equipment used in GLP and GMP-aligned environments: mechanical components conform to ISO 9001-certified manufacturing protocols; electronic modules comply with IEC 61000-4 electromagnetic compatibility standards; and software functionality meets FDA 21 CFR Part 11 requirements for electronic records and signatures—including secure user authentication, immutable audit trails, and electronic signature capture for critical method changes. Column hardware is rated for maximum operating pressures up to 300 bar, ensuring compatibility with modern high-efficiency stationary phases such as Kromasil EternityXT and Kromasil Bio series.

Software & Data Management

Kromasil PrepControl software provides a unified interface for instrument configuration, method development, run execution, and post-run analysis. All acquisition parameters—including flow rate profiles, gradient tables, detector settings, and fraction collection rules—are stored as encrypted XML-based method files. Raw chromatographic data (.chd format) are archived with embedded metadata (operator ID, timestamp, instrument serial number, calibration status). The software supports export to common formats (CSV, PDF, AIA/CDF) for integration with LIMS or ELN platforms. Audit trail records capture every user-initiated action—including method edits, run starts/stops, and calibration events—with timestamps, user IDs, and before/after values. Data backups are configurable via network drive synchronization or scheduled local archive compression.

Applications

• Purification of therapeutic peptides and insulin analogs under cGMP-relevant conditions, supporting impurity profiling per ICH Q5 and Q3B guidelines.
• Isolation of active pharmaceutical ingredients (APIs) from reaction mixtures containing residual catalysts, unreacted starting materials, and regioisomeric by-products.
• Fractionation of plant-derived natural product libraries for structure–activity relationship (SAR) studies and lead compound identification.
• Desalting and buffer exchange of oligonucleotide synthesis crude products prior to lyophilization and QC testing.
• Process validation support—including column lifetime monitoring, system suitability testing (SST), and robustness evaluation across pH, temperature, and flow rate variables.

FAQ

What column dimensions and chemistries are supported by the Kromasil PREPHPLC?
The system supports standard preparative columns with internal diameters from 10 mm to 100 mm and lengths of 100–250 mm. Compatible stationary phases include Kromasil C18, C8, phenyl-hexyl, amino, cyano, and specialized silica variants for chiral or HILIC applications.
Does the system offer compliance documentation for regulated environments?
Yes—factory-installed IQ/OQ documentation packages are available upon request, including test protocols, executed reports, and summary certificates aligned with ASTM E2500 and EU Annex 15 requirements.
Can the PREPHPLC be integrated into an automated laboratory workflow?
It features digital I/O ports and Modbus TCP support for external PLC coordination, as well as API-driven command scripting (via Python or LabVIEW) for integration with robotic sample handlers or downstream analytics platforms.
Is method transfer from analytical to preparative scale supported?
Kromasil PrepControl includes a scale-up calculator that applies linear velocity and mass load scaling principles per USP , enabling consistent retention behavior and resolution preservation across column sizes.
