Wufeng ChroMini LC-80 Integrated Portable Liquid Chromatograph

Overview

The Wufeng ChroMini LC-80 is an integrated, portable high-performance liquid chromatography (HPLC) system engineered for precision, reliability, and operational simplicity in resource-constrained or mobile laboratory environments. Built upon two decades of Wufeng’s dedicated R&D in liquid chromatography instrumentation, the LC-80 implements a compact, modular architecture that consolidates pump, autosampler, column oven, UV-Vis detector, and degasser into a single chassis—minimizing inter-unit tubing length, reducing system dwell volume (< 120 µL), and eliminating unnecessary fluidic interfaces. Its core analytical principle relies on reversed-phase, normal-phase, or ion-exchange chromatographic separation coupled with fixed-wavelength or wavelength-scanning UV-Vis absorbance detection (190–700 nm), enabling quantitative and qualitative analysis of small-molecule organics, pharmaceuticals, agrochemicals, food additives, and environmental contaminants. Designed for robustness under variable ambient conditions, the LC-80 operates without external gas supply or chilled water cooling, making it suitable for field-deployable QC labs, teaching laboratories, pilot-scale process monitoring, and decentralized agricultural testing centers.

Key Features

• Integrated monolithic chassis design reduces total system volume to < 28 L and weight to < 25 kg—enabling benchtop deployment, transport between labs, or use in mobile analytical units.
• High-precision dual-plunger reciprocating pump with active solvent compressibility compensation ensures flow accuracy ±0.2% RSD and pulseless delivery across the full 0.001–5.000 mL/min range.
• Thermostatically controlled column compartment maintains temperature stability of ±0.3 °C from 4–80 °C, supporting method transfer consistency and retention time reproducibility.
• UV-Vis detector features a 10-mm pathlength flow cell, deuterium/tungsten dual-lamp source, and real-time spectral validation—supporting both single-wavelength quantitation and peak purity assessment.
• Autosampler accommodates two independent 54-position 2-mL vial trays (108 total), with programmable injection volumes from 1–50 µL and needle wash capability to minimize carryover (< 0.01%).
• Embedded microcontroller enables standalone operation via USB-connected PC; no external controller or proprietary hardware interface required.

Sample Compatibility & Compliance

The LC-80 supports standard 3.0–4.6 mm ID analytical columns (up to 250 mm length) and is compatible with common HPLC stationary phases including C18, C8, phenyl-hexyl, amino, cyano, and silica. It meets mechanical and electrical safety requirements per IEC 61010-1:2010 and electromagnetic compatibility (EMC) standards per CISPR 11 Group 1, Class B. While not pre-certified for regulated GMP environments, its firmware architecture supports audit-trail-enabling software configurations compliant with FDA 21 CFR Part 11 when paired with validated third-party chromatography data systems (CDS). Method parameters—including flow rate, gradient profile, detector wavelength, and temperature setpoints—are fully traceable and exportable in CSV/ASCII format for GLP documentation.

Software & Data Management

The LC-80 operates exclusively through Wufeng’s ChroMini Workstation software (v3.2+), a Windows-based application providing instrument control, real-time chromatogram visualization, peak integration, calibration curve generation, and report export (PDF, Excel). The software implements role-based user access control, electronic signature capture, and automated data backup to network drives or local SSDs. Raw data files (.chd) retain full acquisition metadata (timestamp, method ID, operator login, hardware configuration checksum), ensuring data integrity per ALCOA+ principles. Integration with LIMS is supported via ODBC-compliant database export and configurable XML result templates.

Applications

• Academic instruction: Ideal for undergraduate chromatography labs due to intuitive interface, visual diagnostics, and built-in method templates for caffeine, paracetamol, and dye separations.
• Agricultural QA/QC: Quantification of pesticide residues (e.g., carbendazim, imidacloprid) in grain extracts using EPA Method 8318-compatible gradients.
• Chemical manufacturing: Assay of monomer purity (e.g., styrene, vinyl acetate) and residual solvents per ASTM D7093 guidelines.
• Feed & food safety: Determination of mycotoxins (aflatoxin B1, ochratoxin A) in animal feed following AOAC 2005.02 extraction protocols.
• Environmental screening: Analysis of phenolic compounds and surfactants in wastewater effluent using isocratic or shallow-gradient methods.

FAQ

Is the LC-80 compliant with 21 CFR Part 11 for regulated pharmaceutical testing?
The hardware and firmware support audit trail, electronic signature, and data integrity functions—but formal Part 11 compliance requires validation of the complete system (instrument + software + IT infrastructure) by the end user per their internal SOPs.
Can the detector perform wavelength scanning during a run?
Yes—the UV-Vis module supports time-programmed wavelength switching and full-spectrum acquisition at up to 100 Hz, enabling peak identification and spectral library matching.
What column oven size does the LC-80 accommodate?
It accepts standard 150 mm × 4.6 mm and 250 mm × 4.6 mm columns with optional guard column holder; maximum column length supported is 300 mm with reduced pressure margin.
Does the autosampler support needle-in-vial or needle-through-cap injection?
It uses needle-through-cap (NTC) mode with adjustable penetration depth and septum-pierce optimization for low carryover across diverse vial cap types.
Is remote monitoring or control possible over LAN or Wi-Fi?
No—the LC-80 communicates exclusively via USB 2.0; network connectivity requires an intermediary PC running the workstation software as a local server node.
