Shimadzu i-Series LC-2070 / LC-2080 High-Performance Liquid Chromatograph

Overview

The Shimadzu i-Series LC-2070 and LC-2080 are high-performance liquid chromatography (HPLC) systems engineered for precision, operational stability, and sustainable laboratory operation. Built upon Shimadzu’s decades of chromatographic expertise, these instruments implement a unified architecture integrating gradient elution, high-pressure pumping, autosampling, column thermostating, and dual-wavelength UV-Vis detection. The LC-2070 supports up to 50 MPa system pressure—suitable for standard reversed-phase, ion-exchange, and size-exclusion applications—while the LC-2080 extends capability to ultra-high-resolution separations with a 70 MPa maximum pressure rating, enabling compatibility with sub-2 µm particle-packed columns and advanced method development workflows. Both models operate on the principle of isocratic or gradient solvent delivery through precisely controlled reciprocating piston pumps, coupled with low-dead-volume flow cells and thermally stabilized optical paths to ensure baseline stability and photometric reproducibility across extended run times.

Key Features

• Intelligent Self-Diagnosis Engine: Real-time monitoring of pump check valve integrity and autosampler needle clogging via integrated fluidic path diagnostics; automatic flagging of deviations beyond configurable thresholds.
• FlowPilot™ Flow Control Technology: Dynamic adjustment of mobile phase flow rate during column oven ramping to prevent thermal shock-induced backpressure spikes and column degradation.
• iCMP™ Column Management Platform: Embedded database logging of column installation date, cumulative runtime, solvent exposure history, and maintenance events—traceable per ICH-GCP and FDA 21 CFR Part 11 audit trail requirements.
• Auto-Recovery Functionality: On-the-fly degassing and bubble purge cycles triggered by pressure variance detection, minimizing manual intervention and preserving retention time reproducibility over multi-day sequences.
• LabSolutions Direct Software Integration: Unified control interface supporting method creation, sequence scheduling, remote instrument status monitoring, and automated post-run shutdown—compatible with Windows-based enterprise IT infrastructure and LIMS connectivity.
• Green Design Elements: Housing components fabricated from certified recyclable polymer composites; optimized packaging volume reducing transport-related CO₂ emissions by ~32% versus prior-generation models; standby power consumption reduced by 95% via adaptive sleep-mode logic.

Sample Compatibility & Compliance

The i-Series accommodates standard 1.5 mL screw-thread vials (216-position tray), 1 mL crimp-top vials (336-position tray), and 4 mL wide-mouth vials (112-position tray), supporting both aqueous and organic solvent matrices without carryover risk. All wetted surfaces—including pump heads, injector rotor seals, and flow cell windows—are chemically resistant to common HPLC solvents (acetonitrile, methanol, THF, buffer salts ≤ 0.1 M). The system meets ISO/IEC 17025:2017 calibration traceability requirements and supports GLP/GMP-compliant operation through LabSolutions CS software, which enforces electronic signatures, version-controlled method storage, and immutable audit logs for all analytical events. UV-Vis detector wavelength accuracy is verified per ASTM E275–22, while flow accuracy conforms to USP chromatographic system suitability criteria.

Software & Data Management

LabSolutions CS provides full lifecycle data governance—from acquisition and peak integration to report generation and raw data archiving. It supports automated system suitability testing (SST) including dwell volume measurement, gradient delay verification, wavelength accuracy validation (using holmium oxide reference), and noise/drift assessment at user-defined wavelengths. All SST results are embedded in PDF reports compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Data files adhere to ASTM E1950-20 standard format, ensuring interoperability with third-party CDS platforms and electronic lab notebooks (ELNs). Remote access is secured via TLS 1.2 encryption and role-based authentication aligned with NIST SP 800-53 Rev. 5 controls.

Applications

These systems serve as primary analytical platforms across pharmaceutical QC/QA (assay, impurity profiling, dissolution testing), environmental monitoring (PAHs, pesticides, pharmaceutical residues in water), food safety (mycotoxins, preservatives, adulterants), and academic research (natural product isolation, polymer characterization, metabolomics sample prep). The LC-2080’s 70 MPa capability enables method transfer from UHPLC to HPLC-class instrumentation without sacrificing resolution—critical for regulatory submissions requiring platform consistency. Its 100 Hz acquisition rate ensures accurate peak shape capture for fast-eluting compounds under narrow peaks (< 2 s width), while the ±0.1 nm wavelength repeatability supports multi-component quantitation in complex biological matrices.

FAQ

What distinguishes the LC-2070 from the LC-2080?
The LC-2080 features an enhanced high-pressure pump module rated to 70 MPa, whereas the LC-2070 is limited to 50 MPa—making the former suitable for sub-2 µm column applications and higher linear velocity methods.
Does the system support 21 CFR Part 11 compliance out of the box?
Yes—when deployed with LabSolutions CS software configured with electronic signature policies, audit trail activation, and secure user access controls, the system satisfies core technical requirements of FDA 21 CFR Part 11.
Can column usage history be exported for regulatory review?
Yes—iCMP data, including column lot numbers, installation timestamps, cumulative runtime, and solvent exposure logs, can be exported as CSV or PDF reports with digital signature embedding.
Is method transfer between i-Series and older Shimadzu LC systems feasible?
Method translation tools within LabSolutions CS enable semi-automated conversion of methods from Prominence and Nexera platforms, accounting for dwell volume differences and gradient delay compensation.
How does the auto-validation function verify detector performance?
It executes a predefined sequence measuring absorbance linearity (using neutral density filters), wavelength accuracy (holmium oxide scan), baseline noise (10-min zero-signal record), and photometric drift (60-min stability test at 254 nm).
