Hanbon NS9002S Simulated Moving Bed Chromatography System

Overview

The Hanbon NS9002S Simulated Moving Bed (SMB) Chromatography System is a high-precision, laboratory-scale preparative liquid chromatography platform engineered for continuous chiral and achiral separation of thermally labile or structurally similar compounds. Unlike conventional batch chromatography, the NS9002S implements true SMB operation based on the principle of counter-current mass transfer in fixed-bed adsorption systems. By cyclically switching inlet/outlet ports across 2–12 column modules—programmatically controlled via high-integrity rotary valves—the system emulates continuous countercurrent movement of the solid-phase adsorbent relative to the liquid-phase feed, eluent, and raffinate streams. This architecture delivers enhanced productivity, superior solvent economy, and higher product purity compared to single-column or batch-mode preparative HPLC, while eliminating mechanical wear, particle attrition, and column plugging inherent in true moving-bed configurations.

Key Features

• Configurable column array supporting 1–12 column arrangements for flexible operational modes: single-column batch purification, multi-column batch recycling, classical SMB, and supercritical/solvent-gradient-enhanced SMB (SSMB).
• High-pressure fluidic architecture rated to 15 MPa (2175 psi), enabling use of sub-2 µm particle size stationary phases and elevated flow rates up to 99.99 mL/min with <0.1% RSD flow precision.
• UV-Vis detector with wavelength accuracy ±1 nm and repeatability ±0.2 nm; baseline noise <0.5 × 10⁻⁵ AU at 254 nm (1 s time constant), optimized for low-concentration fraction monitoring.
• Valve manifold design minimizing system dwell volume (<120 µL total internal volume from pump outlet to detector cell), critical for sharp peak resolution and accurate fraction collection in SMB switching cycles.
• Critical subsystems—including high-pressure pumps, UV detectors, and switching valves—integrated using components from globally recognized industrial suppliers (e.g., Parker, Knauer, Shimadzu) to ensure long-term operational stability and mean time between failures (MTBF) >12,000 hours.
• Full validation support package compliant with pharmaceutical quality systems: documented Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) protocols aligned with ISO/IEC 17025 and ASTM E2500-18 guidelines.

Sample Compatibility & Compliance

The NS9002S accommodates a broad range of sample matrices—including small-molecule APIs, natural product extracts, peptides, and oligonucleotide intermediates—across reversed-phase, normal-phase, chiral, and ion-exchange chemistries. Its modular column configuration allows seamless adaptation to varying adsorption isotherm nonlinearity and selectivity profiles. The system meets essential regulatory expectations for analytical and process development environments: hardware and firmware comply with IEC 61000-6-2/6-4 EMC standards; electrical safety conforms to UL 61010-1 and CE EN 61010-1. All electronic records—including method parameters, chromatograms, and fraction logs—are generated, stored, and audited under FDA 21 CFR Part 11-compliant software architecture with role-based access control, electronic signatures, and immutable audit trails.

Software & Data Management

Control and data acquisition are managed through an integrated SCADA-grade software platform built on Siemens SIMATIC WinCC or GE Digital Proficy Historian frameworks—configurable per client infrastructure requirements. The interface supports real-time visualization of zone pressure differentials, valve position status, UV absorbance trends, and flow synchronization across all columns. Method development tools include automated step-gradient optimization, cycle time simulation, and predictive elution profiling based on equilibrium-dispersive modeling. Raw data is saved in vendor-neutral .CDF (NetCDF) format; processed results export to CSV, PDF, or XML for LIMS integration. All software modules undergo periodic cybersecurity assessment per NIST SP 800-53 Rev. 4 controls and support TLS 1.2+ encrypted communications.

Applications

• Chiral resolution of racemic pharmaceutical intermediates (e.g., β-blockers, NSAIDs, ACE inhibitors) at gram-to-kilogram scale under GMP-aligned process development conditions.
• Purification of monoclonal antibody fragments (Fab, scFv) and ADC linker-payload conjugates where batch chromatography induces aggregation or degradation.
• Separation of geometric isomers (cis/trans), regioisomers, and diastereomers in fine chemical synthesis where conventional HPLC fails to achieve baseline resolution.
• Continuous desalting and buffer exchange of peptide libraries prior to high-throughput screening assays.
• Recovery and concentration of high-value natural products (e.g., ginsenosides, curcuminoids) from crude botanical extracts with >95% recovery yield and <0.5% impurity carryover.

FAQ

What column configurations does the NS9002S support?
The system natively supports 2–12 column arrangements, with software-defined zoning enabling classical 4-zone SMB, 3-zone extraction, or custom multi-zone configurations for asymmetric separations.
Is the system compatible with non-aqueous mobile phases?
Yes—fluidic pathways are constructed from 316L stainless steel and PEEK, rated for compatibility with acetonitrile, methanol, THF, dichloromethane, and supercritical CO₂-based eluents up to 15 MPa.
Can the NS9002S be integrated into an existing automation framework?
It provides OPC UA and Modbus TCP interfaces for bidirectional communication with DCS, MES, or central lab automation systems; full API documentation is included with the IQ/OQ package.
Does the system support method transfer from analytical to preparative scale?
Yes—built-in scaling algorithms correlate retention times, selectivity (α), and capacity factor (k’) from analytical UHPLC methods to SMB cycle time and zone flow ratios, reducing method development time by ~40%.
What validation documentation is provided upon delivery?
A complete DQ/IQ/OQ/PQ suite—including test scripts, executed reports, calibration certificates for all transducers, and 21 CFR Part 11 compliance evidence—is delivered as part of the standard commissioning package.
