Overview
The CSY- Food Safety Rapid Detection Analyzer is a compact, benchtop multi-analyte screening platform engineered for quantitative and qualitative assessment of common chemical contaminants and quality indicators in food matrices. Designed around integrated photometric detection principles—including enzyme-linked immunosorbent assay (ELISA), colorimetric enzymatic reactions, and competitive inhibition assays—the instrument delivers rapid, on-site results within 5–15 minutes per test. It is not a chromatographic or mass spectrometric system; rather, it functions as a standardized optical reader calibrated for pre-formulated test kits (e.g., for pesticide residues, antibiotic traces, mycotoxins, formaldehyde, melamine, nitrite, and heavy metal ions such as lead and cadmium). Its architecture complies with the operational logic defined in ISO/IEC 17025:2017 for testing laboratories using kit-based methods, and supports traceability under GLP-aligned workflows when paired with validated reagent kits and documented SOPs.
Key Features
- Multi-channel photometric measurement at fixed wavelengths (450 nm, 492 nm, 630 nm) optimized for common ELISA and chromogenic assays
- Integrated thermal incubation module (37 °C ± 0.5 °C) with programmable timing (1–30 min), enabling controlled enzymatic reaction kinetics
- Self-calibrating optical path with dual-beam referencing to minimize drift and enhance inter-batch reproducibility
- Onboard touchscreen interface with multilingual UI (English, Spanish, Arabic, Vietnamese) and embedded test protocol library
- USB and RS-232 connectivity for data export to LIMS or local PCs; compatible with CSV and PDF report generation
- Rugged aluminum alloy chassis rated IP20 for laboratory and field-deployable use; CE-marked for EMC and low-voltage safety compliance
Sample Compatibility & Compliance
The CSY- analyzer accepts liquid extracts prepared from solid, semi-solid, or liquid food samples—including dairy products, meat homogenates, vegetable washes, grain extracts, and aquatic product supernatants—following standardized sample preparation protocols outlined in GB/T 5009.x, SN/T series, and AOAC Official Methods. It is intended for use with third-party or OEM-certified test kits meeting ISO 15197:2013 performance criteria for analytical sensitivity and precision. While the instrument itself does not hold FDA 510(k) clearance or EU IVDR certification, its operation conforms to Good Laboratory Practice (GLP) documentation requirements when deployed with audit-ready electronic logs, user access control, and calibration verification records. All firmware versions are validated against ISO 9001:2015 QMS documentation maintained by Shenfen Instruments.
Software & Data Management
The embedded operating system includes role-based user authentication (administrator/operator modes), automatic timestamping of all measurements, and built-in audit trail functionality compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Data files store raw absorbance values, calculated concentrations, pass/fail flags per limit threshold, and operator ID—exportable without modification via USB flash drive. Optional PC software (CSY-DataLink v3.2) enables statistical trend analysis, QC charting (X-bar/R), and batch-level summary reporting aligned with ISO/IEC 17025 clause 7.8. Software binaries are registered with the China National Copyright Administration (Registration No. 2018SR123456), and source code integrity is verified via SHA-256 checksums provided upon request.
Applications
- Routine screening of pesticide residues (organophosphates, carbamates) in fruits and vegetables per GB 2763–2021 MRL thresholds
- Quantitative detection of veterinary drug residues (chloramphenicol, sulfonamides, tetracyclines) in milk and aquaculture products
- Verification of adulterants including melamine in infant formula and starch-based foods
- Nitrite content monitoring in cured meats and fermented vegetables per GB 2760–2022 limits
- Heavy metal ion screening (Pb²⁺, Cd²⁺, Hg²⁺) in rice, tea, and seafood using chelation-based colorimetric kits
- In-process quality control in food manufacturing facilities requiring <15-minute turnaround for release testing
FAQ
Is the CSY- analyzer capable of detecting unlisted analytes not covered by its pre-loaded test protocols?
No. The system relies exclusively on validated, kit-specific algorithms and calibration curves. Custom assay development requires firmware reconfiguration and independent method validation by the end user.
Does the instrument meet FDA 21 CFR Part 11 requirements for electronic records?
It supports core elements (audit trail, electronic signatures, data integrity controls), but full Part 11 compliance depends on site-specific validation, including risk assessment, configuration management, and procedural documentation.
Can test results be integrated into an existing LIMS environment?
Yes—via ASCII-formatted CSV output or optional OPC UA gateway integration (requires CSY-LIMS Bridge module, sold separately).
What is the recommended calibration frequency?
Optical calibration using certified neutral density filters is advised every 90 days or after 500 measurement cycles, whichever occurs first.
Are consumables supplied directly by Shenfen Instruments?
Shenfen provides OEM-labeled test kits and calibration standards; third-party compatible kits may be used if independently verified for metrological equivalence.
