Tianyan TY-SYJCT Colloidal Gold Reader for Veterinary Drug Residue Rapid Detection

Overview

The Tianyan TY-SYJCT Colloidal Gold Reader is a field-deployable, integrated rapid detection instrument engineered for quantitative and semi-quantitative analysis of veterinary drug residues, mycotoxins, pathogen antigens, and hormone contaminants in food and agricultural commodities. It operates on the principle of lateral flow immunoassay (LFIA) signal digitization—capturing high-resolution optical images of colloidal gold-labeled test strips via a calibrated CMOS imaging module, then applying algorithmic CT-line intensity quantification to derive analyte concentration based on standard calibration curves. Designed specifically for regulatory compliance screening in food safety workflows, the device supports simultaneous multi-analyte detection across diverse sample matrices—including meat, eggs, dairy, aquatic products, feed, and raw grains—without requiring laboratory infrastructure or trained technicians. Its architecture aligns with the operational requirements of decentralized testing environments such as slaughterhouses, cold-chain logistics hubs, border inspection posts, and mobile food safety supervision units.

Key Features

• 10.1-inch capacitive touchscreen running Android OS with ARM Cortex-A7 RK3288 quad-core processor (1.88 GHz), enabling responsive multitasking and real-time image processing
• Dedicated colloidal gold detection module featuring motorized track-based strip transport, auto-focus imaging, and dynamic CT-line recognition—eliminating manual threshold adjustment
• Onboard data integration dashboard with automatic weekly/monthly statistical summaries: total tests performed, pass/fail counts, and interactive bar charts—accessible without external software
• Pre-configurable task templates for sample ID, analyte panel, submitting unit, and collection date—reducing entry errors and accelerating throughput
• Universal compatibility with commercial colloidal gold test cassettes from third-party manufacturers—no proprietary consumables lock-in
• Dual-power operation: AC adapter + 6 Ah rechargeable Li-ion battery (runtime ≥ 8 h continuous use); compact footprint (43 × 35 × 20 cm), net weight 5.1 kg
• Secure data management: user-level authentication, role-based access control, audit-trail-capable login logs, and encrypted local storage for ≥200,000 test records
• Firmware over-the-air (FOTA) update capability—targeted, version-controlled remote upgrades without hardware return or service interruption

Sample Compatibility & Compliance

The TY-SYJCT reader accommodates a broad spectrum of sample types following standardized pre-treatment protocols defined in GB/T 5009.x, NY/T 761–2008, and SN/T 1947–2007. Validated matrices include bovine/pork muscle tissue, chicken eggs, raw milk, shrimp homogenates, compound feed, cornmeal, and soybean meal. Detection panels cover critical food safety hazards regulated under China’s Ministry of Agriculture and Rural Affairs (MARA) Announcement No. 250 and the State Administration for Market Regulation (SAMR) Technical Specifications for Rapid Screening Methods. While not certified to ISO/IEC 17025 for accredited testing, the system meets functional equivalence requirements for preliminary screening per GB 2763–2021 (Maximum Residue Limits) and supports GLP-aligned documentation practices including timestamped result export, operator traceability, and tamper-evident digital signature options.

Software & Data Management

The embedded Android application provides end-to-end digital workflow management—from sample registration and assay execution to reporting and cloud synchronization. All results are stored in SQLite databases with SHA-256 hash integrity verification. Data export supports CSV and Excel (.xlsx) formats; reports include QR-coded metadata compliant with GB/T 34068–2017 for traceability. Network connectivity includes dual-mode Wi-Fi (802.11 b/g/n) and 10/100 Mbps Ethernet (RJ45), enabling seamless integration with provincial food safety surveillance platforms (e.g., China Food Safety Information Network). Optional A4 report generation supports customizable templates aligned with national certification standards (e.g., CNAS-CL01:2018 Annex A2). USB 2.0 host interface allows direct data transfer to external drives without driver installation.

Applications

• Routine monitoring of β-agonists (clenbuterol, salbutamol, ractopamine, diethylstilbestrol) in livestock tissues
• Screening for antibiotic residues—including tetracyclines, sulfonamides, fluoroquinolones, nitrofurans, chloramphenicol, and florfenicol—in eggs, aquaculture products, and dairy
• Quantitative detection of mycotoxins (aflatoxin B1/M1, deoxynivalenol, zearalenone, ochratoxin A) in cereals and feedstuffs
• Antigen-based rapid diagnosis of priority animal diseases: avian influenza H5/H7, Newcastle disease virus, foot-and-mouth disease virus (FMDV), porcine reproductive and respiratory syndrome virus (PRRSV), and canine parvovirus
• Field validation of residue clearance intervals during withdrawal periods on farms and feedlots
• Supporting risk-based inspection programs conducted by municipal market regulation bureaus and customs laboratories

FAQ

Does the TY-SYJCT reader require calibration before each use?
No. The system performs automated optical self-calibration upon startup using internal reference standards; full recalibration is recommended only after firmware updates or every 90 days of continuous operation.
Can test results be exported in a format compatible with LIMS systems?
Yes. Raw data and summary reports can be exported as CSV or Excel files with ISO 8601 timestamps, analyte identifiers, and QC flag indicators—facilitating ingestion into common LIMS platforms via FTP or SFTP.
Is the device suitable for use in humid or dusty field environments?
It is rated IP54 for dust and splash resistance; however, extended operation in ambient humidity >85% RH or particulate-heavy settings (e.g., grain silos) requires optional protective housing.
What regulatory documentation accompanies the instrument for import compliance?
CE Declaration of Conformity (EMC & RoHS), Chinese CCC mark certificate, factory ISO 9001:2015 quality system certification, and technical file including optical performance validation reports.
How frequently are new assay templates added to the database?
New test cassette configurations are added quarterly via FOTA updates; users may also manually import validated calibration curves using the built-in curve editor module.
