Ruixin JCX-3SL Multi-Analyte Food Safety Rapid Detection Kit

Overview

The Ruixin JCX-3SL Multi-Analyte Food Safety Rapid Detection Kit is a field-deployable, optical immunoassay-based system engineered for the simultaneous qualitative and semi-quantitative screening of three β-agonist veterinary drug residues—clenbuterol hydrochloride, ractopamine, and salbutamol—in food safety monitoring workflows. It operates on the principle of colloidal gold-labeled lateral flow immunoassay (LFIA), with integrated reflectance photometry for objective signal quantification. Unlike subjective visual interpretation, the JCX-3SL employs a built-in 3-channel optical reader calibrated across 400–680 nm to convert test line intensity into concentration estimates based on preloaded standard curves. Designed for regulatory compliance environments—including slaughterhouse laboratories, feed mills, and provincial food inspection centers—the system delivers results in under two minutes post-sample extraction, supporting high-throughput surveillance without reliance on centralized ELISA or LC-MS/MS infrastructure.

Key Features

• Triple-target detection capability: Simultaneous analysis of clenbuterol, ractopamine, and salbutamol within a single assay run using dedicated test strips and channel-specific calibration.
• Integrated 3-channel photometric reader: Equipped with narrow-band LED sources and silicon photodiodes optimized for 400–680 nm, enabling reproducible reflectance measurement with CV <5% across repeated assays.
• Standardized sample preparation suite: Includes a 12,000 rpm microcentrifuge (max. 1.5 mL tubes), 1–5 mL adjustable-volume pipette, 0.1 g precision electronic balance (300 g capacity), digital timer, and disposable consumables (100 sample cups, 100 capillary pipettes, 50 microcentrifuge tubes).
• Field-ready portable configuration: All components housed in a shock-absorbing, lockable aluminum carrying case (L×W×H: 42 × 32 × 18 cm) compliant with IATA carry-on dimensions and IP54 dust/moisture resistance.
• Pre-validated assay performance: Each lot of test strips undergoes batch-level verification per ISO/IEC 17025-accredited protocols for sensitivity, specificity, and cross-reactivity against structurally related β-agonists (e.g., terbutaline, fenoterol).

Sample Compatibility & Compliance

The JCX-3SL supports homogenized animal tissue (muscle, liver), centrifuged urine supernatant, and ground feed matrices following standardized extraction protocols outlined in GB/T 22286–2008 (Chinese National Standard for β-agonist detection in feeds) and SN/T 1924–2011 (Entry-Exit Inspection and Quarantine Industry Standard). Cross-reactivity testing confirms <5% interference from common veterinary antibiotics (tetracyclines, sulfonamides) and endogenous compounds (cortisol, creatinine). The system meets basic requirements for GLP-aligned documentation: all test strips include lot-specific QR-coded traceability; reader firmware logs timestamped results with operator ID and instrument serial number—supporting audit readiness per China’s SAMR Regulation No. 10 of 2021 on rapid testing recordkeeping.

Software & Data Management

The embedded firmware (v2.3.1) stores up to 500 test records locally with export via USB 2.0 to CSV format. No cloud connectivity or remote data transmission is implemented—ensuring full data sovereignty per GDPR Article 17 and China’s PIPL requirements. Calibration curves are factory-loaded and locked; users may perform daily blank calibration using provided control strips but cannot modify algorithmic parameters. Audit trail functionality includes immutable timestamps, user login history, and strip lot number association—satisfying minimum traceability criteria referenced in USP Analytical Instrument Qualification for rapid screening tools used in GMP-adjacent settings.

Applications

• Frontline screening at livestock markets and abattoirs prior to carcass release.
• Feed mill quality assurance during raw material intake and finished product release.
• Regulatory rapid response units conducting unannounced inspections under China’s “Four Strictest” food safety enforcement framework.
• Academic research labs validating novel extraction methods or comparing LFIA performance against reference LC-MS/MS methods (AOAC 2010.01 validated).
• Export certification support for shipments to ASEAN and GCC countries where rapid immunoassay data is accepted as preliminary evidence under bilateral SPS agreements.

FAQ

What sample types require homogenization prior to testing?
Animal tissue samples (e.g., pork liver, beef muscle) must be homogenized with extraction buffer (provided) and centrifuged at ≥10,000 × g for 5 min to obtain clear supernatant.
Is the JCX-3SL reader compatible with third-party lateral flow strips?
No. Optical filters and calibration algorithms are optimized exclusively for Ruixin-manufactured test strips bearing the JCX-3SL lot-specific barcodes.
How often must the reader be recalibrated?
Factory calibration remains valid for 12 months under normal operating conditions (15–30°C, <70% RH); daily blank calibration using control strips is mandatory before first use each shift.
Does the kit include extraction reagents?
Yes—each kit contains 100 mL of proprietary extraction buffer, 50 mL of dilution buffer, and 10 mL of wash solution, all supplied in sterile, single-use vials with lot-controlled expiration dates.
Can results be integrated into LIMS systems?
CSV exports can be manually imported into LIMS platforms supporting generic text-based ingestion; no native HL7 or ASTM E1384 interfaces are provided.
