JASCO LC-4000 Series High-Performance Liquid Chromatograph

Overview

The JASCO LC-4000 Series is a modular, high-fidelity liquid chromatography platform engineered for precision, flexibility, and regulatory readiness in modern analytical laboratories. Built upon JASCO’s decades of expertise in optical instrumentation and fluidic control systems, the LC-4000 implements classical reversed-phase, normal-phase, and size-exclusion chromatographic separations using robust isocratic or gradient elution protocols. Its architecture supports multiple operational modes—including UHPLC (ultra-high-performance LC), RHPLC (rapid high-resolution LC), semi-preparative LC, and routine analytical HPLC—through interchangeable pump modules, detector configurations, and temperature-controlled flow paths. The system operates on a unified pressure-resistant fluidic backbone rated to 130 MPa, enabling compatibility with sub-2-µm particle columns while maintaining long-term baseline stability and low dwell volume (< 500 µL). All components adhere to ISO/IEC 17025 traceability principles for calibration and performance verification.

Key Features

• Modular pump architecture: Selectable configurations including quaternary low-pressure mixing pumps, binary high-pressure gradient pumps, and semi-preparative pumps—all field-upgradable and serviceable without system disassembly.
• Front-access consumables design: Pump seals, lamp housings, flow cells, and autosampler syringe assemblies are accessible from the front panel, minimizing downtime during routine maintenance.
• Integrated column oven with extended thermal range: Precisely controlled from ambient +10 °C to 200 °C (±0.1 °C stability), supporting method development for thermally labile compounds and high-temperature LC applications.
• Multi-detector compatibility: Native support for PDA (photodiode array), UV-Vis absorbance, fluorescence, refractive index (RI), circular dichroism (CD), and optical rotation detectors—each optimized for signal-to-noise ratio, photometric linearity, and spectral fidelity.
• Compact footprint and stackable module layout: Designed for space-constrained environments; modules interlock via standardized mechanical and electrical interfaces compliant with IEC 61000-6-3 EMC requirements.

Sample Compatibility & Compliance

The LC-4000 accommodates a broad spectrum of sample matrices—including pharmaceutical actives, biologics (mAbs, peptides), natural products, polymers, and environmental extracts—across injection volumes from 0.1 µL to 100 µL. Its 180-position autosampler tray supports standard 2-mL vials and accommodates custom plate formats via optional adapters. All wetted surfaces employ chemically resistant materials (e.g., sapphire, titanium, PEEK, and stainless steel 316L) suitable for aggressive mobile phases (e.g., TFA, HFIP, high-pH buffers). The system meets key international compliance frameworks: ASTM D7592 (HPLC method validation), ISO 17025:2017 (testing laboratory competence), and USP (chromatography). It is fully compatible with GLP and GMP environments when deployed with validated ChromNAV 2.0 software.

Software & Data Management

ChromNAV Ver. 2.0 serves as the certified chromatographic data system (CDS) for the LC-4000 Series. Fully compliant with FDA 21 CFR Part 11, it provides electronic signatures, audit trails with immutable timestamps, role-based user access control, and secure data archiving. The GUI is customizable: users define dashboards showing only relevant instrument status, real-time chromatograms, peak tables, or spectral overlays. Advanced processing includes automated peak integration with retention time alignment, multi-component quantitation (linear/non-linear calibration curves), 3D contour plots (wavelength × time × absorbance), spectral deconvolution, and batch report generation in PDF/A-1a format. Raw data (.jcd, .dat) and processed results are stored in vendor-neutral formats supporting third-party reprocessing.

Applications

• Pharmaceutical QC/QA: Release testing of APIs per ICH Q2(R2), impurity profiling, stability-indicating assays, and dissolution method transfer.
• Biopharmaceutical characterization: mAb aggregation analysis (SEC-HPLC), glycan mapping (HILIC), charge variant separation (IEX), and peptide mapping (RP-HPLC).
• Academic research: Natural product isolation guidance, reaction monitoring, chiral resolution (with CD detection), and polymer molecular weight distribution (GPC).
• Environmental and food safety: Pesticide residue screening (multi-residue methods), mycotoxin quantification, and vitamin profiling in fortified foods.
• Materials science: Solvent additive analysis in OLED formulations, surfactant purity assessment, and nanomaterial dispersion stability evaluation.

FAQ

What gradient delay volumes are typical for LC-4000 pump configurations?

Standard binary high-pressure gradient modules exhibit a dwell volume of ≤ 450 µL; low-pressure quaternary systems are ≤ 750 µL—both verified per ASTM D7592 Annex A3.
Can ChromNAV 2.0 be validated for 21 CFR Part 11 compliance in-house?

Yes—JASCO provides IQ/OQ documentation templates, test scripts, and traceability matrices aligned with GAMP 5. Installation and operational qualification can be executed by qualified personnel under QA oversight.
Is the CD detector capable of simultaneous CD, UV, and g-factor output?

Yes—the JASCO CD detector (model CD-4000) acquires all three signals synchronously at 100 Hz with hardware-level synchronization, eliminating post-acquisition interpolation artifacts.
Does the column oven support active cooling below ambient temperature?

No—the LC-4000 column oven is heating-only (ambient +10 °C to 200 °C); for sub-ambient operation, external recirculating chillers may be integrated via auxiliary temperature sensor input.
Are firmware updates provided free of charge during the warranty period?

Yes—JASCO delivers all firmware and ChromNAV software updates at no cost for the duration of the standard 24-month warranty, with optional extended support plans available.
