SQ-CQ Series Solid Phase Extractor
Overview
The SQ-CQ Series Solid Phase Extractor is a high-performance laboratory instrument designed to streamline solid-phase extraction (SPE) workflows. It replaces manual SPE methods with automated precision, minimizing human error and improving reproducibility. Developed for industrial and research laboratories, this system supports applications ranging from environmental pollutant detection to drug metabolite analysis. Its modular architecture accommodates diverse SPE cartridge formats (e.g., 1–100 mL) and solvent combinations, making it adaptable to ISO, EPA, and other regulatory methods. The system integrates seamlessly with analytical instruments like LC-MS, ensuring end-to-end traceability in quality control environments.
Structure and Working Principle
The extractor comprises a robotic arm, solvent delivery system, and cartridge holding platform, all controlled via touchscreen interface. Samples are loaded into SPE cartridges, where target compounds bind to the sorbent phase. The system then sequentially applies conditioning, loading, washing, and elution solvents under programmable pressure/vacuum conditions. Key components include corrosion-resistant pumps for precise solvent metering and PTFE fluid paths to prevent sample contamination. Advanced models feature barcode scanning for cartridge identification and cloud-based data logging, ensuring compliance with 21 CFR Part 11 regulations in pharmaceutical applications.
Key Features
Automation capabilities distinguish the SQ-CQ Series, with batch processing of up to 24 samples simultaneously. Variable flow rate control (0.1–10 mL/min) accommodates sensitive matrices, while built-in solvent savings modes reduce operational costs. The system's anti-cross-contamination design includes disposable tips and self-cleaning functions. For laboratories requiring flexibility, optional modules allow for offline evaporation or fraction collection. The user interface supports method storage for 50+ protocols, with password-protected access levels to maintain data integrity in multi-user environments.
Application Areas
Primary applications include pesticide residue analysis in agricultural products, opioid detection in forensic toxicology, and wastewater monitoring under EPA 3535A guidelines. Food safety labs utilize it for mycotoxin extraction (e.g., aflatoxins in grains), while pharmaceutical QC teams apply it for API purification. In environmental sectors, the system processes large volumes of water samples for PFAS or hydrocarbon analysis. Its reproducibility (±2% RSD) makes it particularly valuable for contract research organizations (CROs) requiring audit-ready documentation for client deliverables.
Maintenance and Precautions
Routine maintenance includes monthly inspection of solvent lines for leaks and replacement of worn seals (recommended annually). Use only HPLC-grade solvents to prevent pump damage, and purge the system with inert gas when storing for extended periods. For optimal performance, avoid particulate-heavy samples without pre-filtration. The manufacturer provides calibration kits for flow rate verification. In case of error codes (e.g., pressure deviations), the troubleshooting manual outlines step-by-step diagnostics for common issues.
B2B Procurement Guide
When evaluating suppliers, verify certifications like ISO 9001 and request performance validation data (e.g., recovery rates for your target analytes). Consider total cost of ownership, including consumables (e.g., cartridge racks) and service contracts. Leading manufacturers offer application support for method development. For high-volume labs, prioritize vendors providing rapid replacement parts shipping. Bulk purchase discounts (5+ units) typically reduce per-unit costs by 15–20%. Some suppliers bundle training sessions or method templates for common applications like veterinary drug residues in meat products.
