Hitachi LaChrom Elite High-Performance Liquid Chromatography System

Overview

The Hitachi LaChrom Elite HPLC system is a high-precision, modular liquid chromatography platform engineered for reproducible gradient separations in regulated and research environments. Built upon Hitachi’s proprietary high-pressure quaternary pumping architecture, the system employs a dual-stage mixing design—“pre-pump confluence, post-pump mixing”—to achieve sub-0.2% RSD gradient accuracy across 0–100% B composition. Its core fluidic control relies on real-time pressure feedback loops integrated into the L-2130 pump’s stepper motor driver, enabling microsecond-level flow correction and minimizing pulsation-induced baseline noise. The system operates under high-pressure gradient conditions up to 60 MPa (8700 psi), supporting both reversed-phase and HILIC applications with retention time stability ≤0.02 min over 24-hour continuous runs. As an imported instrument originally manufactured in the United States under Hitachi High-Tech’s quality management system (certified to ISO 9001:2015), the LaChrom Elite conforms to foundational requirements for method transfer and validation in pharmaceutical QC, environmental testing, and academic core facilities.

Key Features

• Quaternary high-pressure gradient pump (L-2130) with EPIC (Enhanced Pressure Interference Compensation) technology for active suppression of pressure transients during gradient transitions
• L-2400 UV/VIS detector featuring holographic concave grating optics—designed and manufactured in-house by Hitachi, one of only three global producers of precision ruled diffraction gratings
• L-2485 fluorescence detector with programmable excitation/emission wavelength scanning and high quantum efficiency photomultiplier tube (PMT)
• L-2200 autosampler incorporating PASS (Pump-Autosampler Synchronization System) to align injection timing with gradient cycle phase, improving retention time reproducibility (RSD < 0.15%)
• Integrated system organizer supplying stabilized 24 V DC power to all modules—eliminating AC-line-induced electronic noise and protecting sensitive detectors from voltage spikes
• Front-accessible maintenance architecture: all consumables (check valves, seals, frits) and critical service points located on the instrument’s frontal panel without disassembly
• Dual-gemstone ball check valves (sapphire/ruby) ensuring leak-free unidirectional flow and extended service life under aggressive mobile phases

Sample Compatibility & Compliance

The LaChrom Elite supports standard 3.0–4.6 mm ID analytical columns and accommodates column oven temperature control from ambient +5 °C to 85 °C (L-2300). Its detector linearity spans 4 orders of magnitude (0.001–2.0 AU for UV, 0.1–10,000 RFU for fluorescence), suitable for trace-level quantitation in compliance with USP , ICH Q2(R2), and EPA Method 8330B workflows. All modules include integrated leak sensors that trigger immediate shutdown and event logging upon detection of fluid ingress. When operated with validated methods and enabled audit trail functionality (via optional software license), the system meets documentation requirements for GLP and GMP environments—including full electronic record retention, user access controls, and 21 CFR Part 11–compliant signature capture.

Software & Data Management

The system ships with Hitachi’s LaChrom Elite Control Software (v3.x), offering bilingual interface support (English and Chinese) and context-sensitive help documentation fully localized in both languages. Raw data files are stored in vendor-neutral .hcd format, exportable to ASCII, CSV, or CDF for third-party processing (e.g., Chromeleon, OpenLab CDS). The software includes built-in report customization tools supporting multi-parameter overlays, peak purity assessment, and automated calibration curve generation. For laboratories managing multiple instruments, the software supports daisy-chained control of two independent LaChrom Elite systems from a single workstation—reducing infrastructure overhead while maintaining individual audit trails and method libraries.

Applications

This refurbished LaChrom Elite system is routinely deployed in pharmaceutical stability-indicating assays (e.g., forced degradation studies per ICH Q5C), pesticide residue analysis in food matrices (AOAC 2007.01), polycyclic aromatic hydrocarbon (PAH) profiling in soil extracts (EPA 8310), and oligonucleotide purity assessment in biomanufacturing QC. Its dual-detection capability enables simultaneous UV absorbance and native fluorescence monitoring—particularly valuable for vitamin analysis (e.g., B2, B12), flavonoid characterization, and protein-bound tryptophan quantification. The system’s robustness and documented longevity make it well-suited for teaching laboratories requiring reliable, low-cost entry into modern HPLC methodology.

FAQ

Is this unit fully tested and certified prior to shipment?
Yes. Each LaChrom Elite system undergoes functional verification at SpectraLab Scientific’s ISO/IEC 17025-accredited calibration lab, including flow accuracy (±0.5% at 1.0 mL/min), gradient composition linearity (±0.3% absolute), UV wavelength accuracy (±1 nm), and baseline noise (< ±0.5 × 10⁻⁵ AU).

Does the 6-month warranty cover parts and labor?
Yes—the warranty includes all components, labor, and remote technical support. Extended service plans with on-site response options are available upon request.

Can this system be upgraded to support mass spectrometry coupling?
The L-2130 pump and L-2200 autosampler feature standard LC-MS interface ports (1/16″ PEEK tubing, 10–100 µL loop compatibility); however, no MS source or interface hardware is included in this configuration.

Are original manuals and software installation media provided?
All units ship with digital copies of the complete English-language user manuals, firmware update packages, and licensed software installers—delivered via secure download link with activation credentials.

What documentation accompanies the instrument for regulatory audits?
A Certificate of Inspection, Factory Calibration Report, and Refurbishment Summary (including replaced wear parts and performance verification data) are supplied with each system. Full traceability records are retained for 10 years.
