Ruixin CNY-2418C Intelligent Pesticide Residue Rapid Tester

Overview

The Ruixin CNY-2418C Intelligent Pesticide Residue Rapid Tester is a dedicated benchtop analytical instrument engineered for high-throughput screening of organophosphorus and carbamate pesticide residues in agricultural commodities. It operates on the well-established enzyme inhibition principle—specifically, the acetylcholinesterase (AChE) inhibition assay—quantified via spectrophotometric measurement at 412 nm. This method is standardized under Chinese national food safety regulations, including GB 5009.199–2016 (replacing 2003) and NY/T 448–2021 (updated from 2001), and aligns with internationally recognized rapid screening protocols endorsed by Codex Alimentarius for pre-screening applications. The instrument delivers semi-quantitative results expressed as percentage inhibition relative to a blank control, enabling rapid pass/fail decisions at point-of-intake or decentralized testing sites such as farmers’ markets, agri-logistics hubs, and municipal food safety supervision stations.

Key Features

• 24 independent optical detection channels with simultaneous sample processing—supports up to 240 samples per hour under standard operating conditions.
• 10.1-inch industrial-grade capacitive touchscreen (1024 × 600 resolution) with IP65 front-panel protection, 400 cd/m² brightness, and integrated stylus support—including digital signature capture for audit-compliant reporting.
• Embedded Android 7.0 platform (quad-core 1.8 GHz CPU, 2 GB RAM, 16 GB eMMC + microSD slot) enabling local data management, offline operation, and secure firmware updates.
• Integrated dual-network connectivity: IEEE 802.11 b/g/n Wi-Fi and 10/100 Mbps Ethernet (RJ45); optional LTE/5G module support for real-time cloud synchronization in low-infrastructure environments.
• Automated workflow logic: auto-detection of sample presence in cuvette slots, real-time inhibition calculation, pass/fail classification per channel, and on-device thermal report printing.
• Self-diagnostic system with embedded instructional video library—facilitates field-level troubleshooting and operator training without external technical support.
• Built-in searchable database for sample names and testing entities, supporting pinyin-based fuzzy search for efficient data entry in Mandarin-speaking operational contexts.

Sample Compatibility & Compliance

The CNY-2418C is validated for homogenized extracts from fresh produce (leafy vegetables, fruits), cereals, tea leaves, and aqueous rinse solutions. Sample preparation follows AOAC Official Method 2007.01–based extraction protocols using phosphate buffer and acetone/water mixtures. While not intended for regulatory confirmation analysis, its performance meets the sensitivity and reproducibility requirements for preliminary screening under China’s Food Safety Law (Article 112) and State Administration for Market Regulation (SAMR) Technical Guidelines for Rapid Detection of Pesticide Residues in Edible Agricultural Products. Instrument calibration and verification are traceable to NIM (National Institute of Metrology, China) reference standards. Data integrity safeguards include timestamped records, operator ID logging, and immutable result archiving—supporting GLP-aligned documentation practices.

Software & Data Management

Data acquisition, processing, and export are handled through Ruixin’s proprietary AgriTrace™ software suite, pre-installed on the device. All measurements are time-stamped, geotagged (via optional GPS/AGPS), and stored locally with SHA-256 hash integrity checks. Export formats include CSV and Excel (.xlsx) via dual USB 2.0 ports or network transfer. Cloud integration supports RESTful API communication with Ruixin’s certified SaaS platform—enabling multi-tier dashboards for district-level supervisors, batch-level traceability mapping, and automated alerting when inhibition thresholds exceed preset limits (e.g., ≥50% inhibition triggers Level-1 flag). Audit trails comply with basic FDA 21 CFR Part 11 principles (electronic signatures, event logs, user access controls), though formal validation packages must be implemented separately per site-specific GxP requirements.

Applications

• Routine surveillance testing at wholesale markets, smart farmers’ markets, and supermarket QA labs.
• Field-deployable screening during harvest inspections and cold-chain handover points.
• Supporting municipal food safety monitoring programs mandated under China’s “Four Strictest” regulatory framework.
• Pre-harvest scouting in cooperative farming zones to guide safe pre-harvest intervals (PHIs).
• Educational use in agricultural vocational colleges for hands-on training in rapid food safety analytics.

FAQ

What pesticides does the CNY-2418C detect?
It detects acetylcholinesterase-inhibiting compounds—primarily organophosphates (e.g., chlorpyrifos, dimethoate) and carbamates (e.g., carbaryl, methomyl)—but does not identify specific analytes or quantify individual residues.
Can this instrument replace GC-MS or LC-MS/MS in official testing?
No. It is a qualitative/semi-quantitative screening tool. Positive results require confirmatory analysis by accredited laboratories using chromatographic methods per GB 23200 series standards.
Is calibration required before each use?
Daily blank and control calibrations are recommended; full photometric calibration is performed annually using factory-certified neutral density filters.
Does the device support multi-language UI beyond Chinese?
The base firmware supports Simplified Chinese only; English UI localization requires OEM firmware customization and is available upon request for international distribution partners.
How is data security ensured during cloud transmission?
All data in transit is encrypted via TLS 1.2+; stored data at rest uses AES-256 encryption. Role-based access control (RBAC) is enforced on the cloud platform.
