Unimicro Technologies MMT-3000 Multi-Mycotoxin Analysis System

Overview

The Unimicro Technologies MMT-3000 Multi-Mycotoxin Analysis System is a purpose-built, integrated high-performance liquid chromatography (HPLC)-based analytical platform engineered for the simultaneous quantification and confirmation of over 20 regulated and emerging mycotoxins in complex biological and agricultural matrices. Leveraging post-column derivatization coupled with dual-wavelength fluorescence detection and optional UV/Vis absorbance detection, the system implements validated chromatographic separation principles aligned with AOAC Official Method 2005.08, ISO 15837:2003, and relevant sections of the Chinese Pharmacopoeia (ChP) 2020 Edition. Its architecture integrates a precision quaternary gradient pump, low-dead-volume autosampler with temperature-controlled sample tray, programmable post-column reactor, and dual-channel fluorescence detector—configured to resolve structurally diverse mycotoxin classes—including aflatoxins (B₁, B₂, G₁, G₂, M₁), trichothecenes (deoxynivalenol, T-2 toxin, HT-2 toxin), zearalenone, fumonisins (B₁, B₂), ochratoxin A, patulin, cyclopiazonic acid, enniatins, alternariol and its derivatives, amatoxins (α-amanitin, β-amanitin), phallotoxins (phalloidin), virotoxins, muscimol, ibotenic acid, psilocybin, norbaeocystin, bufotenine, and orellanine—within a single run under harmonized chromatographic conditions.

Key Features

• Integrated multi-module HPLC platform with synchronized control of solvent delivery, injection, derivatization, and detection modules via unified firmware
• Post-column photochemical or chemical derivatization system enabling enhanced sensitivity and selectivity for non-fluorescent or weakly fluorescent mycotoxins (e.g., fumonisins, deoxynivalenol)
• Temperature-stabilized autosampler (4–40 °C) supporting up to 120 vials per rack with needle wash and carryover suppression algorithms
• Dual-channel fluorescence detector with independently adjustable excitation/emission wavelengths (200–650 nm range) and real-time spectral validation
• Modular column oven (ambient–80 °C, ±0.1 °C stability) compatible with reversed-phase C18, HILIC, and mixed-mode stationary phases
• Pre-installed, validated method packages covering ChP, GB 5009.22–2016, GB/T 18979–2003, and EU Commission Regulation (EC) No 401/2006 workflows—including sample extraction, cleanup (immunoaffinity columns or QuEChERS), and matrix-matched calibration protocols

Sample Compatibility & Compliance

The MMT-3000 supports direct analysis of extracts from cereals, oilseeds, nuts, spices, dried fruits, animal feed, traditional Chinese medicinal herbs (e.g., licorice root, ginseng, coix seed), infant formula, and environmental swab samples. All pre-configured methods comply with Good Laboratory Practice (GLP) requirements and support audit-ready data integrity per FDA 21 CFR Part 11 when deployed with optional electronic signature and audit trail modules. System qualification documentation includes IQ/OQ/PQ protocols aligned with ISO/IEC 17025:2017 and CNAS-CL01:2018 criteria. Method validation reports include specificity, linearity (R² ≥ 0.999), LOD/LOQ (≤ 0.1 µg/kg for aflatoxin B₁), precision (RSD ≤ 5% intra-day, ≤ 8% inter-day), and recovery (70–120% across five matrix types).

Software & Data Management

The system operates under Unimicro ChromaLink™ v3.2 software—a 64-bit Windows-based platform compliant with ALCOA+ data governance principles. It provides full lifecycle traceability: method creation with parameter locking, raw data encryption (AES-256), electronic signatures with role-based access control, and automated report generation conforming to ISO/IEC 17025 Annex A.2 requirements. Integrated database management supports structured storage of chromatograms, calibration curves, QC results, and sample metadata; all searchable by compound, batch ID, analyst, or date range. Audit trails are immutable, time-stamped, and exportable in PDF/A-2b format for regulatory submission.

Applications

The MMT-3000 serves as a reference-grade solution for national food safety laboratories (e.g., CNCA-accredited institutions), pharmaceutical QC units verifying herbal raw material purity, feed safety monitoring programs, and public health agencies conducting surveillance of mycotoxin contamination in outbreak investigations. It enables compliance testing against maximum residue limits (MRLs) defined in Chinese National Standards (GB series), EU regulations (EC No 1881/2006), Codex Alimentarius standards, and US FDA guidance levels. Its modular design permits expansion into LC-MS/MS readiness through optional interface kits.

FAQ

Does the MMT-3000 support LC-MS/MS coupling?
Yes—optional HPLC-MS interface modules (electrospray ionization source, flow-splitting configuration) are available for method transfer and confirmatory analysis.
Are method validation documents included with the system?
Yes—each pre-installed mycotoxin method package includes full validation reports per ICH Q2(R2) guidelines, including robustness testing across column lots and instrument platforms.
Can the system be configured for GLP-compliant routine operation?
Yes—when equipped with ChromaLink™ v3.2 with Part 11 module, it meets FDA 21 CFR Part 11, EU Annex 11, and WHO TRS 996 Annex 5 requirements for electronic records and signatures.
What sample preparation kits are recommended for use with the MMT-3000?
Unimicro-certified immunoaffinity columns (IACs) for aflatoxins, ochratoxin A, and zearalenone; AOAC-validated QuEChERS kits for multi-class screening; and solid-phase extraction (SPE) cartridges optimized for polar mycotoxins (e.g., fumonisins, enniatins).
Is remote system monitoring and diagnostics supported?
Yes—the system supports secure remote access via TLS 1.2-encrypted VPN connection for real-time performance monitoring, predictive maintenance alerts, and firmware updates.
