Shimadzu LC-2050 Integrated Liquid Chromatograph

Overview

The Shimadzu LC-2050 is a factory-original, Japan-sourced integrated high-performance liquid chromatograph (HPLC) belonging to the i-Series platform — Shimadzu’s next-generation analytical architecture engineered for precision, reproducibility, and remote-operational integrity. Built upon Couette-flow-based solvent delivery, low-diffusion flow cell design, and thermally stabilized optical detection modules, the LC-2050 implements a fully integrated gradient system comprising quaternary pump, autosampler, column oven, and dual-wavelength UV-Vis detector (SPD-20A) in a single compact chassis. Its core measurement principle relies on differential absorbance at user-defined wavelengths (190–700 nm), enabling quantitative and qualitative analysis of small molecules, pharmaceuticals, natural products, and synthetic polymers under isocratic or gradient elution conditions. Designed for regulated environments, the system meets foundational requirements for method transferability across i-Series platforms (e.g., LC-2030, LC-2040, LC-2060), supporting seamless migration of validated protocols without requalification.

Key Features

• Integrated i-Series architecture with unified firmware control and hardware synchronization
• Quaternary low-pulsation pump delivering flow rates from 0.001–10.000 mL/min with ≤0.07% RSD flow precision
• Autosampler with 100-position tray capacity, needle wash station, and injection volume range 0.1–100 µL (0.1 µL increments)
• Column oven with temperature control from 4°C above ambient to 85°C (±0.1°C stability)
• SPD-20A UV-Vis detector featuring dual-wavelength simultaneous monitoring, 10 mm flow cell, and baseline noise < ±0.25 × 10⁻⁵ AU at 254 nm
• Embedded Analytical Intelligence (AI) functions including Flow Rate Wizard and Mobile Phase Wizard for automated method optimization
• i-PeakFinder and i-PDeA II algorithms for automated peak detection, integration, and baseline correction — trained on >10,000 reference chromatograms
• Remote operation via LabSolutions LC software v5.9x or later, compatible with Windows 10/11 (64-bit) and Citrix virtual desktop infrastructure

Sample Compatibility & Compliance

The LC-2050 supports reversed-phase, normal-phase, ion-exchange, size-exclusion (GPC/SEC), and ligand-exchange chromatographic modes using standard 2.1–4.6 mm ID columns up to 30 cm in length. It is routinely deployed in laboratories operating under GLP, GMP, and ISO/IEC 17025 frameworks. The system satisfies critical pharmacopeial requirements: USP system suitability criteria (tailing factor ≤2.0, resolution ≥2.0, %RSD ≤1.0 for replicate injections), EP 2.2.46 detector linearity validation (r² ≥0.999 over 3 orders of magnitude), and ASTM D7493 for residual solvent quantification. All firmware versions shipped with this unit include audit trail logging compliant with FDA 21 CFR Part 11 (electronic signatures, user access levels, immutable event records).

Software & Data Management

Controlled exclusively by Shimadzu LabSolutions LC software (v5.92 or higher), the LC-2050 provides full method development, sequence management, real-time chromatogram visualization, and report generation. Data files are stored in native .lcd format (binary) with embedded metadata (instrument ID, operator, timestamp, method parameters). Raw data export supports CSV, ASCII, and AIA (.cdf) formats for third-party processing. Software modules include i-PeakFinder (adaptive peak detection), i-PDeA II (peak deconvolution and area normalization), and GPC Analysis Module (for molecular weight distribution calculation using polystyrene standards). All software installations undergo SHA-256 checksum verification; license keys are tied to instrument serial number and require periodic online activation.

Applications

• Pharmaceutical QC/QA: Assay and impurity profiling per USP monographs (e.g., duloxetine HCl, pramipexole dihydrochloride); system suitability testing per USP ; forced degradation studies
• Food & Beverage: Simultaneous quantification of 12 synthetic dyes (e.g., Allura Red AC, Tartrazine) using PDA detection; carbohydrate analysis via RID-20A under ligand-exchange mode at 85°C; low-UV analytes (e.g., sugars, polyols) via ELSD coupling
• Environmental Monitoring: PAHs, PCBs, and phenolic compounds in water matrices using RF-20Axs fluorescence detection (LOD < 5 pg on-column)
• Polymer Characterization: GPC/SEC analysis of polystyrene standards using LabSolutions GPC module; additive screening (e.g., antioxidants, plasticizers) via UV detection at 220/280 nm

FAQ

Is this LC-2050 unit certified for use in FDA-regulated laboratories?

Yes — all operational firmware includes 21 CFR Part 11-compliant audit trail functionality, electronic signature support, and role-based access control. Full validation documentation package (IQ/OQ/PQ templates) is provided upon request.
Can legacy methods from LC-2030 or LC-2040 be directly imported?

Yes — Shimadzu guarantees backward compatibility for method files, sequence files, and calibration curves between LC-2030/2030plus → LC-2050 and LC-2040/2040plus → LC-2060.
What maintenance history is available for this used instrument?

This unit underwent full functional verification at Shimadzu’s Osaka Calibration Center prior to export, including pump pressure test (≤35 MPa), autosampler carryover assessment (<0.005%), and detector wavelength accuracy check (NIST-traceable holmium oxide filter). Service logs covering the last 24 months are included.
Does the one-year warranty cover both parts and labor?

Yes — the warranty covers all components except consumables (seals, fuses, lamps, columns) and damage resulting from improper operation, voltage fluctuation, or unauthorized modification.
Is LabSolutions software included with the system?

Yes — a perpetual, instrument-locked license for LabSolutions LC v5.92 is pre-installed and activated. No subscription fees apply.
