Hanbon NS4101 Analytical High-Performance Liquid Chromatography System

Overview

The Hanbon NS4101 Analytical High-Performance Liquid Chromatography (HPLC) System is a modular, benchtop-grade chromatographic platform engineered for method development, analytical quantification, and preparative-scale process transfer in regulated and research laboratory environments. Based on classical reversed-phase, normal-phase, and ion-exchange separation principles, the system employs high-precision reciprocating piston pumps and dual-wavelength UV-Vis detection to deliver reproducible retention time stability (<0.1% RSD), baseline noise ≤ ±0.5 × 10⁻⁵ AU, and wavelength accuracy ±1 nm across the 190–700 nm spectral window. Its 40 MPa pressure rating supports sub-2 µm particle-packed columns and UHPLC-compatible methods when operated with appropriate column hardware and mobile phase compatibility. Designed for seamless integration into early-stage bioprocess analytics and synthetic chemistry workflows, the NS4101 serves as both an analytical verification tool and a scalable bridge to pilot-scale purification.

Key Features

• Electronically damped flow control architecture ensures flow precision ≤ ±0.1% RSD and gradient composition accuracy ≤ ±0.2% over full range (0.001–9.999 mL/min)
• Floating-piston pump head design minimizes mechanical stress on seal assemblies, extending service life under continuous operation at elevated backpressures
• Dual-wavelength UV-Vis detector enables simultaneous monitoring at two user-defined wavelengths—critical for co-elution assessment, peak purity analysis, and multi-analyte quantitation without re-injection
• Wetted path materials configurable in 316L stainless steel, titanium alloy, or PEEK—supporting compatibility with aggressive solvents (e.g., TFA, HFIP), high-salt buffers, and corrosive mobile phases
• Single-position manual or optional autosampler interface (up to 50 µL injection volume) with low carryover (<0.01%) and precise loop-based metering
• Modular detector expansion capability: compatible with optional refractive index (RI) and evaporative light scattering (ELSD) detectors for non-UV-absorbing analytes

Sample Compatibility & Compliance

The NS4101 accommodates standard analytical columns (2.1–4.6 mm ID, up to 250 mm length), spring-loaded guard columns, dynamic axial compression (DAC) columns, and multi-functional axial compression systems—enabling direct translation from analytical screening to gram-scale purification. All fluidic components comply with ISO 8573-1 (compressed air purity class 4.2.2) for pneumatic actuation where applicable. The system architecture supports audit-trail-enabled operation when integrated with compliant chromatography data systems (CDS); raw data files adhere to ASTM E2524-21 metadata standards for chromatographic traceability. While ambient-only column compartment limits temperature-dependent method robustness, it meets GLP-compliant storage and qualification requirements for routine QC testing of small-molecule APIs, fermentation broth supernatants, and botanical extracts per USP , EP 2.2.46, and ISO 17025 Annex A.3.

Software & Data Management

The NS4101 operates with Hanbon’s proprietary ChromoLink™ acquisition software, supporting real-time chromatogram visualization, peak integration via tangent skim and valley-to-valley algorithms, and customizable report templates compliant with 21 CFR Part 11 requirements—including electronic signatures, user access levels (admin/operator/auditor), and immutable audit trails for all method edits, sequence changes, and result exports. Raw data are stored in vendor-neutral .CDF (NetCDF-based chromatographic data format) with embedded instrument configuration logs, enabling third-party reprocessing in OpenLab CDS, Chromeleon, or Empower. Data export supports CSV, PDF, and XML formats; integration with LIMS is achievable via HL7 or RESTful API extensions upon request.

Applications

• Quality control of active pharmaceutical ingredients (APIs) and intermediates per ICH Q2(R2) validation guidelines
• Separation and quantification of organic acids, amino acids, nucleosides, and flavonoids in natural product extracts
• Stability-indicating assays for forced degradation studies (acid/base/oxidative/thermal)
• Process monitoring of microbial fermentation broths—including penicillins, cephalosporins, and statin precursors
• Method scouting and column selectivity evaluation using diverse stationary phases (C18, phenyl-hexyl, HILIC, cyano)
• Support for preparative fraction collection via external trigger signal output (TTL-compatible) to third-party fraction collectors

FAQ

Does the NS4101 support column oven temperature control?
No—the system features ambient-only column compartment operation. For temperature-sensitive separations, external column heaters or thermostatted enclosures are recommended.
Is gradient delay volume characterized and compensatable in software?
Yes—ChromoLink™ includes built-in gradient delay calibration routines using step-gradient profiling, allowing users to define and correct for dwell volume (typical range: 0.8–1.5 mL depending on configuration).
Can the UV-Vis detector perform spectral scanning?
No—this is a fixed-wavelength dual-channel detector. Full-spectrum PDA functionality is available only on higher-tier Hanbon models (e.g., NS6100 series).
What regulatory documentation is provided with the system?
Each unit ships with Factory Acceptance Test (FAT) report, IQ/OQ protocol templates, material compliance certificates (RoHS, REACH), and 21 CFR Part 11 readiness declaration.
Is remote monitoring supported?
Yes—via optional Ethernet-enabled controller module and secure HTTPS-based web interface for real-time status, alarm logging, and method queue management.
