Raykol Fotector-08HT High-Throughput Automated Solid Phase Extraction System

Overview

The Raykol Fotector-08HT is a fully automated, high-throughput solid phase extraction (SPE) system engineered for precision, reproducibility, and unattended operation in regulated analytical laboratories. It implements standardized SPE methodology—comprising conditioning, sample loading, washing, and elution—via programmable fluidic control and robotic positioning. Unlike semi-automated or manual systems, the Fotector-08HT eliminates operator-dependent variability by executing all steps with mechanical repeatability, consistent flow dynamics, and precise solvent delivery. Its architecture supports both conventional polymeric or silica-based SPE cartridges and membrane-based SPE devices, enabling method flexibility across diverse analyte classes—including polar pesticides, persistent organic pollutants (POPs), pharmaceutical residues, and forensic toxicants. Designed for integration into ISO/IEC 17025-compliant workflows and GLP/GMP environments, the system adheres to fundamental principles of method validation: accuracy, intermediate precision, and robustness.

Key Features

• Eight parallel processing channels with independent fluidic control, enabling simultaneous conditioning, loading, washing, and elution across all positions.
• Programmable flow rate modulation from 0 to 120 mL/min—adjustable per step and per channel—to optimize retention, wash efficiency, and elution recovery for varied sorbent chemistries (e.g., C18, HLB, SCX, SAX, Florisil).
• Eight dedicated solvent reservoirs with sealed, inert pathways—constructed entirely from platinum-coated fittings, PTFE tubing, and PEEK manifolds—to ensure chemical compatibility with aggressive solvents (e.g., DCM, acetone, methanol, hexane, ammonium hydroxide solutions) and prevent metal leaching or adsorptive losses.
• Compact footprint (W × D × H: 650 × 600 × 620 mm) designed for seamless installation inside standard laboratory fume hoods, minimizing volatile organic compound (VOC) exposure and supporting OSHA and EU Directive 2004/37/EC occupational safety requirements.
• Integrated pressure monitoring and real-time flow verification at each channel to detect cartridge clogging, air bubble formation, or seal failure—triggering automatic pause and alert logging without process interruption.
• Modular rack design accommodates standard 1-mL, 3-mL, 6-mL, and 12-mL SPE cartridges as well as 96-well plate-compatible membrane formats, supporting both discrete and high-density sample preparation protocols.

Sample Compatibility & Compliance

The Fotector-08HT processes aqueous, biological (urine, plasma, serum), environmental (wastewater, surface water, soil extracts), and food matrix samples—including homogenized tissue digests and fortified extracts—without modification to core hardware. Its universal cartridge/membrane interface ensures compatibility with commercially available SPE products from leading vendors (e.g., Waters, Agilent, Thermo Fisher, Phenomenex). The system meets foundational requirements for regulatory compliance: it supports audit-trail-enabled method storage, user-access-level permissions, and electronic signature capability—facilitating alignment with FDA 21 CFR Part 11, EU Annex 11, and ISO/IEC 17025 Clause 7.7 (Method Validation and Verification). All wetted materials comply with USP Class VI biocompatibility standards and ASTM F2028 for polymer performance in analytical fluid handling.

Software & Data Management

Controlled via Raykol’s proprietary SPEStudio™ software (v4.2+), the Fotector-08HT provides a validated Windows-based interface for method development, sequence scheduling, and real-time monitoring. Software features include drag-and-drop protocol builder, multi-step gradient programming, event-triggered notifications (email/SNMP), and export of raw log files in CSV and XML formats for LIMS integration. Audit trails record every user action—including login/logout, method edit history, run start/stop timestamps, and error events—with immutable timestamping and digital signature support. Data integrity safeguards include automatic backup to network drives, encrypted local storage, and optional integration with enterprise-grade identity management systems (e.g., Active Directory).

Applications

• Food safety testing: Multi-residue analysis of organophosphates, neonicotinoids, and mycotoxins in fruits, vegetables, and dairy matrices per AOAC 2012.01 and EN 15662:2018.
• Environmental monitoring: Extraction and concentration of PAHs, PCBs, phthalates, and PFAS from wastewater, sediment, and air particulate filters in accordance with EPA Methods 3535A, 3546, and ISO 18856.
• Clinical and forensic toxicology: Clean-up of whole blood, urine, and oral fluid prior to LC-MS/MS quantification of opioids, benzodiazepines, amphetamines, and synthetic cannabinoids under CAP-accredited workflows.
• Pharmaceutical QC: Residual solvent removal and impurity enrichment from drug substance intermediates per ICH Q2(R2) guidelines.

FAQ

Does the Fotector-08HT support method transfer from manual or semi-automated SPE protocols?

Yes—its step-wise programming interface allows direct translation of existing SOPs, including dwell times, flow rates, and solvent sequences, with built-in validation tools for recovery and breakthrough assessment.
Can the system handle viscous or particulate-laden samples without clogging?

Pre-filtration is recommended for samples with suspended solids >5 µm; optional inline syringe filters (0.45 µm PTFE) and pressure-limiting algorithms mitigate risk during loading.
Is remote monitoring supported over secure networks?

Yes—SPEStudio™ includes TLS-encrypted web dashboard access, enabling real-time status viewing, alarm alerts, and emergency pause/resume via authenticated HTTPS session.
What maintenance intervals are recommended for long-term operational stability?

Primary maintenance includes quarterly calibration of peristaltic pump rollers and annual replacement of PTFE seals and solvent lines—documented in the included GLP-compliant maintenance log template.
How does the Fotector-08HT ensure cross-channel reproducibility?

Each channel operates with independent fluidic control, calibrated flow sensors, and synchronized valve actuation—validated per ISO 5725-2:2019 for intra-batch RSD ≤3.2% (n=6) across eight replicates under identical conditions.
