ANPRO SKJ-IA/04 Mycotoxin Quantitative Rapid Test Analyzer for Zearalenone and Multi-Toxin Screening

Overview

The ANPRO SKJ-IA/04 Mycotoxin Quantitative Rapid Test Analyzer is an engineered field-deployable immunoassay platform designed for the precise, on-site quantification of zearalenone (ZEN) and six major mycotoxins—including aflatoxin B1 (AFB1), deoxynivalenol (DON), ochratoxin A (OTA), fumonisin B1 (FB1), and T-2 toxin—in cereals, feedstuffs, and processed food matrices. Unlike conventional qualitative lateral flow strips, this instrument implements a patented colloidal gold signal quantification algorithm calibrated against traceable reference standards. It operates on the principle of competitive immunochromatography: analyte in the extracted sample competes with immobilized conjugate for binding sites on anti-mycotoxin antibodies pre-coated on the nitrocellulose membrane. The intensity of the test line—measured via dual-wavelength reflectance photometry—is inversely proportional to analyte concentration and converted into quantitative results (ppb or ppm) using pre-loaded, lot-specific calibration curves. This architecture eliminates manual interpretation bias and delivers reproducible data compliant with ISO/IEC 17025-aligned laboratory practices.

Key Features

• Quantitative readout with ≤10-minute turnaround per sample—no HPLC or LC-MS/MS infrastructure required
• Simultaneous analysis of up to six samples in a single assay cycle, supporting high-throughput screening at receiving docks or feed mills
• Pre-calibrated, strip-specific standard curves embedded in each test card; no user handling of certified reference standards
• 7-inch capacitive touchscreen interface with intuitive icon-driven workflow—designed for non-specialist operators with minimal training
• Integrated thermal printer for immediate hard-copy reporting; optional timestamp, GPS geotagging, and operator ID logging
• Wi-Fi and USB connectivity for secure data export to LIMS, ERP, or national grain safety monitoring platforms (e.g., China’s Grain Quality Traceability System)
• Test strips stored at ambient temperature (15–30 °C); individually foil-sealed to ensure ≥18-month shelf life without refrigeration

Sample Compatibility & Compliance

The SKJ-IA/04 is validated for use with homogenized ground samples of maize, wheat, barley, soybean meal, corn gluten meal, and compound animal feed. Extraction protocols follow AOAC Official Method 2005.02 and GB 5009.209–2016, requiring only aqueous methanol (e.g., 70% v/v) and centrifugation. All six target mycotoxins meet performance criteria established by the National Grain Quality Inspection Center (NGQIC) under China’s grain safety regulatory framework. While not FDA 21 CFR Part 11–certified out-of-the-box, the system supports audit-trail configuration (user log, result modification history, time-stamped printouts) to align with GLP/GMP documentation requirements during internal quality audits. Cross-reactivity profiles for each assay are documented per ISO 15238:2017 guidelines on immunoassay specificity.

Software & Data Management

Firmware version 3.2+ includes encrypted local database storage (≥5,000 test records), CSV export capability, and configurable data upload intervals to cloud endpoints via TLS 1.2. The onboard software enforces role-based access control (admin/operator modes), automatic firmware update notifications, and QC flagging for out-of-range internal controls. Raw reflectance values, calibration metadata, and environmental sensor logs (ambient temperature/humidity) are retained alongside final concentrations. API documentation is available for integration with third-party food safety dashboards adhering to RESTful conventions and JSON payload schema.

Applications

• Grain elevators and silos: rapid acceptance/rejection decisions at intake based on ZEN and AFB1 thresholds per GB 2715–2016
• Feed manufacturing plants: in-process verification of raw material compliance prior to batching
• Contract laboratories: supplemental screening tool preceding confirmatory LC-MS/MS analysis
• Regulatory inspection units: mobile deployment for unannounced field sampling in rural production zones
• Research institutions: longitudinal mycotoxin exposure studies in cereal supply chains under controlled storage conditions

FAQ

What extraction solvents are compatible with the SKJ-IA/04 assays?
Aqueous methanol (70% v/v) or acetonitrile/water (80:20 v/v) as specified in GB 5009.209–2016; no derivatization or cleanup steps required.
Can the instrument store calibration curves for multiple test strip lots simultaneously?
Yes—each sealed test card contains an NFC tag or QR code that auto-loads its unique calibration parameters upon insertion.
Is method validation data available for international regulatory submissions?
NGQIC validation reports (in English) and inter-laboratory study summaries (n=12 labs) are provided upon request for EU Commission Regulation (EC) No 401/2006 alignment assessment.
Does the system support multi-toxin co-detection on a single strip?
No—each test strip targets one mycotoxin class; however, six independent strips can be read in parallel within one instrument run.
What is the minimum detectable concentration for zearalenone?
The limit of quantitation (LOQ) is 1.2 ppb in maize matrix, verified per ISO 11843-2:2000 under routine operating conditions.
