Shimadzu Prominence Plus LC-20A Series High-Performance Liquid Chromatograph

Overview

The Shimadzu Prominence Plus LC-20A Series is a high-performance liquid chromatography (HPLC) system engineered for precision, robustness, and regulatory compliance in modern analytical laboratories. Based on Shimadzu’s six-decade heritage in chromatographic instrumentation, this series integrates proven fluidic architecture with enhanced pressure capability—up to 66 MPa for the LC-20ADXR pump module and 44 MPa for the LC-20AT—enabling compatibility with sub-3 µm particle-packed columns for fast, high-resolution separations. The system operates on classical reversed-phase, normal-phase, ion-exchange, and size-exclusion chromatography principles, delivering consistent retention time reproducibility (<0.02 min SD), low baseline noise, and linear dynamic range across diverse analyte classes. Designed for routine and method-development workflows alike, the Prominence Plus LC-20A supports both isocratic and multi-step gradient elution with real-time dwell volume compensation and solvent compressibility correction algorithms—critical for method transfer and inter-laboratory comparability.

Key Features

• Modular architecture with independent, hot-swappable modules—including LC-20AT (44 MPa) and LC-20ADXR (66 MPa) binary pumps, SIL-20ACXR autosampler, CTO-20AC column oven, and SPD-M20A photodiode array detector—ensuring long-term serviceability and field-upgradability.
• Autosampler with dual-tray support: accommodates up to 192 positions via two standard 96-well plates or mixed vial formats (1 mL, 1.5 mL, 4 mL), with programmable needle wash, injection speed control, and low carryover (<0.005%) verified per USP .
• Column oven with extended temperature range (−10 °C to 85 °C, optional refrigerated module) ensures precise thermal control for method robustness, especially for temperature-sensitive biomolecules and chiral separations.
• UV-Vis detection across 190–700 nm with 1 nm wavelength accuracy and <±0.5 nm photometric linearity deviation; supports simultaneous multi-wavelength acquisition and spectral library matching.
• Integrated pressure monitoring at pump outlet and column inlet with real-time overpressure shutdown and diagnostic logging—meeting ISO/IEC 17025 preventive maintenance requirements.

Sample Compatibility & Compliance

The Prominence Plus LC-20A supports aqueous, organic, and mixed mobile phases—including TFA, HFBA, and high-salt buffers—across pH 1.0–12.0 when paired with inert flow path components. It complies with key international standards for analytical instrumentation: ASTM E2656 (HPLC system performance verification), ISO 17025:2017 (clause 6.4.3 on equipment validation), and USP Chromatography. All hardware and software components are designed for GLP/GMP environments: autosampler tray identification, column usage tracking, and electronic signature-enabled audit trails align with FDA 21 CFR Part 11 requirements when deployed with LabSolutions CS network edition. System qualification documentation—including IQ/OQ templates and PQ protocol examples—is provided for seamless integration into regulated pharmaceutical and biotech QC labs.

Software & Data Management

Controlled exclusively via Shimadzu LabSolutions LC software (available in standalone, DB, and CS editions), the system delivers full lifecycle data integrity. LabSolutions CS implements role-based access control, automated backup, immutable raw data archiving, and electronic signature workflows compliant with ALCOA+ principles. The platform natively supports LIMS integration through ASTM E1578-compliant interfaces and offers bidirectional communication with enterprise systems via ODBC and RESTful API extensions. Peak integration uses second-derivative detection and adaptive baseline modeling; quantitation supports internal standard, external standard, and standard addition methods—with uncertainty propagation reporting per EURACHEM/CITAC Guide. All processing parameters, sequence files, and instrument logs are digitally signed and timestamped, satisfying GxP audit readiness requirements.

Applications

The Prominence Plus LC-20A serves as a primary analytical platform across multiple regulated and research-intensive domains. In pharmaceutical development, it performs assay, related substances, and stability-indicating assays per ICH Q2(R2) guidelines. For biopharmaceuticals, it enables intact mAb analysis, peptide mapping (post-tryptic digestion), and glycan profiling using HILIC and SEC modes. Environmental labs deploy it for EPA Method 8330B (PAHs), 8082 (PCBs), and 549.2 (pesticides); food safety applications include mycotoxin screening (aflatoxins, ochratoxin A) and vitamin quantification (A, D, E, K) per AOAC Official Methods. Its flexibility extends to academic research in metabolomics (UHPLC-grade resolution at 44 MPa), polymer characterization (GPC/SEC), and natural product isolation tracking.

FAQ

What column dimensions and particle sizes are supported?
The system supports analytical columns from 2.1 mm × 30 mm to 4.6 mm × 250 mm ID, with particle sizes ranging from 1.7 µm to 5 µm. Optimal performance is achieved with 2–3 µm particles under 66 MPa operation.

Is gradient delay volume adjustable?
Yes—system dwell volume can be measured and compensated via built-in gradient delay test function; user-defined values are applied during method execution to ensure accurate gradient timing.

Can the system operate unattended overnight?
Fully supported via LabSolutions scheduler with automatic power-down, tray repositioning, and error recovery protocols; validated for >72-hour continuous runs with PDA detector stability monitoring.

Does it support method transfer from legacy Shimadzu systems?
Yes—backward compatibility with Class VP and LCsolution methods is maintained through native import wizards and parameter mapping logic, minimizing revalidation effort.

What validation documentation is included?
Factory-issued Performance Qualification (PQ) report, Certificate of Conformance, and electronic copies of IQ/OQ protocols aligned with ASTM E2656 and EU Annex 15.
