Overview
The Ruixin JT-108SC is a dedicated immunoassay-based rapid detection platform engineered for quantitative and semi-quantitative analysis of antibiotic residues in aquatic food matrices. It employs colloidal gold immunochromatographic assay (CGIA) principles—where target analytes (e.g., chloramphenicol, enrofloxacin, nitrofurans, malachite green) competitively bind to antibody-conjugated gold nanoparticles—and integrates high-resolution CCD imaging with embedded AI-driven image processing to convert qualitative lateral flow strip signals into objective, traceable numerical outputs. Unlike visual interpretation, the JT-108SC eliminates observer bias by standardizing optical density measurement across six independent channels, enabling reproducible quantification of C-line and T-line intensities, CT ratios, and colorimetric profiles within the visible spectrum (380–680 nm). Its design targets high-throughput screening in aquaculture farms, cold-chain logistics hubs, wholesale markets, and regulatory laboratories where rapid (<3 min/test), on-site decision-making is critical to food safety compliance.
Key Features
- Six-channel parallel detection architecture enables simultaneous analysis of up to six test strips—maximizing throughput without cross-contamination or mechanical sample handling.
- 10.1-inch capacitive touchscreen running Android OS v11, featuring intuitive icon-based navigation, multilingual UI (English preloaded), and context-sensitive help videos accessible directly from the instrument interface.
- High-fidelity CCD sensor (≥5 MP resolution) with auto-exposure and white-balance calibration ensures consistent image capture under variable ambient lighting conditions.
- On-device AI algorithm performs real-time strip validity verification—automatically rejecting invalid cards (e.g., missing C-line, fluid front misalignment) prior to quantification.
- Integrated thermal printer supports three output formats: adhesive-label print (for traceable product tagging), thermal roll paper (for lab notebooks), and A4 PDF export (via USB or network)—all embedding GS1-compliant QR codes per China’s “Edible Agricultural Products Qualification Certificate” requirements.
- Embedded SD card slot (up to 128 GB) stores ≥1,000,000 test records—including raw images, CT values, timestamps, operator IDs, GPS geotags (when enabled), and environmental metadata (ambient temperature/humidity).
- Modular communication suite includes dual-mode networking (Wi-Fi + Gigabit Ethernet), optional 4G LTE module, and USB host/device ports—enabling seamless synchronization with Ruixin Cloud or third-party LIMS via RESTful API or SFTP.
Sample Compatibility & Compliance
The JT-108SC accepts standardized colloidal gold test strips validated for over 25 antibiotic classes commonly regulated in aquatic products—including nitrofurans (furazolidone, furaltadone), chloramphenicol, sulfonamides, fluoroquinolones (enrofloxacin, ofloxacin), tetracyclines (oxytetracycline), macrolides (erythromycin), aminoglycosides (streptomycin, gentamicin), and phenicols (florfenicol, thiamphenicol). Sample preparation follows AOAC Official Method 2012.01 and GB/T 22338–2008 protocols: homogenization, extraction with acetonitrile/buffer, centrifugation, and filtration. Instrument firmware and calibration standards are traceable to NIM (National Institute of Metrology, China) reference materials. While not certified to ISO/IEC 17025 as a standalone system, its data structure, audit log generation, and user role management align with GLP/GMP documentation practices and facilitate 21 CFR Part 11 readiness when deployed with validated cloud infrastructure.
Software & Data Management
Firmware v3.2+ delivers full local data governance: encrypted SQLite database with SHA-256 hashing, time-stamped audit trails (user login/logout, test initiation, result modification), and configurable access levels (Admin, Technician, Viewer). All results export in CSV, PDF, or XML formats—retaining original image files and metadata. The Ruixin Cloud platform provides centralized dashboard analytics: batch trending, geographical heatmaps, inter-laboratory comparison reports, and automated alerting for out-of-specification results. Data retention policies comply with China’s Measures for the Administration of Agricultural Product Quality and Safety Monitoring (MOA Order No. 12). Third-party integrations (e.g., SAP QM, LabVantage) are supported via HL7 or custom JSON schema mapping.
Applications
- Routine screening at aquaculture harvest points to verify pre-market residue compliance before shipment.
- Import inspection at port-of-entry laboratories performing rapid triage prior to confirmatory LC-MS/MS analysis.
- Quality assurance in seafood processing facilities—monitoring raw material intake and finished product release.
- Government-led surveillance programs tracking regional antibiotic usage patterns and resistance emergence trends.
- Cooperative extension services delivering on-farm diagnostics with immediate certificate generation for traceable sales channels.
FAQ
Does the JT-108SC require external calibration standards for daily operation?
No—factory-calibrated optical path and internal reference strip validation eliminate daily recalibration. However, QC checks using Ruixin-certified control strips are recommended before each testing session.
Can the instrument store and recall historical calibration curves for different antibiotics?
Yes—up to 50 analyte-specific calibration profiles can be loaded via SD card or cloud sync, each containing multi-point curve fit parameters (logistic 4PL, linear, or polynomial) derived from Ruixin’s in-house validation studies.
Is the device suitable for untrained operators in rural settings?
Yes—the interface guides users step-by-step through strip insertion, timing, and result interpretation; offline video tutorials cover sample prep, troubleshooting, and printer maintenance.
How does the system ensure data integrity during network outages?
All tests execute locally; results queue automatically upon reconnection and synchronize with timestamp preservation, preventing data loss or duplication.
What cybersecurity measures are implemented for cloud-connected units?
TLS 1.2+ encryption for data-in-transit, AES-256 encryption for data-at-rest, mandatory two-factor authentication for cloud admin access, and regular penetration testing per Ruixin’s ISO/IEC 27001-aligned ISMS framework.
