Overview
The Ruixin CNY-1218DJ Multi-Function Pesticide Residue Rapid Tester is an integrated analytical platform engineered for high-throughput, field-deployable screening of pesticide residues in agricultural commodities. It combines dual detection modalities—quantitative spectrophotometric analysis based on enzyme inhibition (for organophosphates and carbamates) and semi-quantitative colloidal gold immunochromatographic assay (for broad-spectrum pesticides including pyrethroids, neonicotinoids, fungicides, and herbicides)—within a single ruggedized instrument. Designed for compliance with national food safety surveillance protocols in China (GB/T 5009.199, NY/T 448, and related technical guidelines), the system delivers rapid (<15 min per sample), on-site results without requiring laboratory infrastructure or trained chemists. Its architecture supports regulatory-grade data integrity through audit-trail-enabled operations, time-stamped measurements, and encrypted cloud synchronization—enabling seamless integration into provincial food safety monitoring networks and qualified agricultural product traceability systems.
Key Features
- Hybrid detection engine: Simultaneous operation of 12-channel photometric measurement (based on acetylcholinesterase inhibition kinetics) and 3-channel colloidal gold strip reader (expandable to 10 channels), enabling cross-validated results for critical analytes.
- 10.1-inch industrial-grade capacitive touchscreen with IP65 front-panel rating, 400 cd/m² luminance, and glove-compatible touch response—optimized for ambient outdoor use in markets, farms, and inspection stations.
- Embedded thermal printer compliant with China’s “Qualified Agricultural Product Certificate” (NY/T 3173–2017) formatting requirements; supports both real-time thermal report generation and A4 export via USB or network.
- Android 7.0 operating system with dedicated firmware: Preloaded with >1,000 standardized crop and pesticide name entries (aligned with China’s National Pesticide Registration Database), supporting pinyin-based fuzzy search and barcode-assisted sample ID entry.
- Real-time data transmission: Native MQTT and HTTPS APIs enable direct upload to provincial cloud platforms (e.g., National Food Safety Traceability System); supports TLS 1.2 encryption and configurable data retention policies.
- On-device multimedia guidance: Integrated video tutorials (localized in Mandarin) and voice-prompted workflows reduce operator training time; handwritten digital signature capture ensures chain-of-custody documentation.
Sample Compatibility & Compliance
The CNY-1218DJ is validated for homogenized extracts from fresh produce (leafy vegetables, fruits, tea leaves), cereals (rice, wheat, corn), and dried herbs. Sample preparation follows standardized QuEChERS-inspired extraction protocols compatible with AOAC 2007.01 and GB/T 20770–2006. The instrument meets electromagnetic compatibility (EMC) requirements per GB/T 18268.1–2010 and safety standards per GB 4793.1–2007. While not FDA 21 CFR Part 11 certified out-of-the-box, its audit-log architecture—including user login timestamps, result modification history, and firmware version tracking—supports GLP-aligned validation for domestic regulatory audits and third-party certification (e.g., CNAS-accredited labs).
Software & Data Management
Firmware includes embedded database management with local storage of ≥50,000 test records (including raw absorbance values, inhibition rates, strip image captures, GPS metadata if enabled, and operator IDs). All data fields are exportable in CSV/Excel format via USB or SFTP. Cloud synchronization supports role-based access control (RBAC), automated daily backups, and RESTful API endpoints for integration with LIMS or ERP systems. Audit logs record every instrument action—including calibration events, reagent lot registration, and report generation—with SHA-256 hashing for tamper evidence. Optional remote diagnostics allow OEM-level firmware updates and configuration push via secure OTA channel.
Applications
- Routine screening at wholesale markets, farmers’ cooperatives, and agro-processing facilities prior to distribution.
- On-farm verification of pre-harvest intervals and pesticide application records under Good Agricultural Practice (GAP) programs.
- Regulatory field inspections by county-level agricultural bureaus and market supervision administrations.
- Verification testing for edible agricultural product qualification certificates (e.g., “Edible Agricultural Product Qualification Certificate” per MOA Notice No. 2 [2020]).
- Teaching and capacity-building in vocational agricultural colleges and extension centers.
FAQ
What pesticide classes does the CNY-1218DJ detect?
It detects organophosphates (e.g., chlorpyrifos, omethoate), carbamates (e.g., carbofuran, isoprocarb), synthetic pyrethroids (e.g., cypermethrin, deltamethrin), neonicotinoids (e.g., imidacloprid), fungicides (e.g., mancozeb, thiophanate-methyl), and herbicides (e.g., paraquat, acetochlor), as defined in China’s current Maximum Residue Limits (MRLs) list (GB 2763–2021).
Is method validation documentation available?
Yes—Ruixin provides instrument-specific validation reports per CNAS-CL01:2018, including precision (RSD ≤8%), linearity (R² ≥0.992), and limit-of-detection confirmation against reference standards from NIM (National Institute of Metrology, China).
Can the device be calibrated externally?
Yes—absorbance calibration uses NIST-traceable neutral density filters; colloidal gold channel calibration employs certified reference strips. Calibration intervals are configurable (default: 30 days) and logged automatically.
Does it support multi-language UI?
Currently supports Simplified Chinese only; English-language firmware is available upon request for export-configured units with modified regulatory compliance modules.
What is the warranty and service coverage?
Standard 24-month parts-and-labor warranty; extended service contracts include annual on-site performance verification and reagent compatibility testing.
