LabTech SPE2000 Fully Automated Solid Phase Extraction System

Overview

The LabTech SPE2000 is a fully automated, multi-channel solid phase extraction (SPE) system engineered for high-throughput, reproducible sample preparation in regulated and research laboratories. It implements standardized cartridge-based SPE methodology—comprising conditioning, loading, washing, and elution steps—under precise programmable control. The system leverages positive-pressure solvent delivery and vacuum-assisted flow management to ensure consistent bed packing, uniform flow rates across channels, and minimal channel-to-channel variability. Its architecture supports trace-level analyte enrichment from complex matrices including food homogenates, environmental water, agricultural extracts, and petrochemical process streams. The integrated online filtration module enables direct processing of turbid or suspended-particle-containing samples—such as meat tissue digests or soil leachates—without manual pre-filtration, significantly reducing analyst intervention and cross-contamination risk.

Key Features

• Fully automated, unattended operation for up to 80 samples per batch (8-channel configuration), with sequential or parallel processing modes.
• Dual-mode column handling: motorized column sealing rods accommodate 1 mL, 3 mL, and 6 mL SPE cartridges without hardware reconfiguration.
• Onboard inline filtration unit with disposable polypropylene or PTFE membrane filters (0.45 µm or 0.22 µm), activated automatically during sample loading for particulate-rich matrices.
• Complete sample bottle rinsing post-loading: integrated spray nozzle delivers precise solvent pulses to recover residual analytes from vial walls, improving recovery by ≥5% for low-concentration targets (e.g., PFAS, tetracyclines).
• Modular large-volume capability: optional peristaltic pump and 20-L reservoir interface enable direct processing of bulk aqueous samples—ideal for drinking water compliance testing per EPA Method 537.1 or ISO 21675.
• Chemical compatibility: all fluidic pathways contacting solvents or samples are constructed from PTFE, PEEK, and borosilicate glass—ensuring inertness toward aggressive eluents (e.g., 0.1% NH₄OH in methanol) and minimizing background contamination.

Sample Compatibility & Compliance

The SPE2000 processes liquid, semi-liquid, and homogenized solid extracts across diverse regulatory domains. It is routinely deployed in laboratories performing analyses aligned with EPA Methods 508.1, 525.3, 537.1, and 8270; ISO standards 17993, 21675, and 19592; and Chinese standard HJ 676–2013. Its design facilitates method transfer from manual or semi-automated SPE protocols, with built-in validation tools for flow rate consistency, fraction collection accuracy, and pressure monitoring. All operational logs—including method parameters, start/stop timestamps, error events, and user actions—are timestamped and digitally signed, supporting FDA 21 CFR Part 11 compliance when paired with LabTech’s optional secure authentication and electronic signature module.

Software & Data Management

The system runs on an embedded Android 11 platform with a 10.1″ HD touchscreen interface. The LabTech SPE Control Suite provides drag-and-drop workflow programming, real-time channel status visualization, and dynamic method adjustment during run execution. Each method stores complete metadata: column type, solvent sequences, dwell times, vacuum setpoints, and filter usage logs. Export options include CSV, PDF, and XML formats compatible with LIMS integration via HL7 or ASTM E1384 interfaces. Audit trails are immutable and stored locally with SHA-256 hashing; optional network backup ensures redundancy and long-term archival per ISO/IEC 17025 clause 7.5.2.

Applications

• Food safety: simultaneous cleanup of veterinary drug residues (e.g., fluoroquinolones, sulfonamides) from milk, muscle, and honey prior to LC-MS/MS analysis.
• Environmental monitoring: isolation of per- and polyfluoroalkyl substances (PFAS) from surface water, wastewater, and groundwater at sub-ng/L levels.
• Agricultural testing: extraction of pesticide multiresidues from fruit/vegetable extracts and soil pore water.
• Petrochemical QA/QC: removal of interfering hydrocarbons from crude oil fractions prior to PAH quantification.
• Clinical & forensic toxicology: phospholipid removal and analyte enrichment from plasma or urine prior to HRAM-MS screening.

FAQ

Does the SPE2000 support method validation documentation?
Yes—the system generates comprehensive validation reports covering flow precision (RSD ≤ 2.5%), column breakthrough testing logs, and carryover assessments per ICH Q2(R2) guidelines.
Can it be integrated into an existing laboratory automation framework?
Yes—it features RS-232, Ethernet, and USB host ports, and supports custom API calls for integration with robotic sample handlers or enterprise LIMS platforms.
Is the online filtration module reusable or single-use?
It uses disposable membrane cassettes (pre-sterilized, certified low-extractables); each cassette processes up to 96 samples before replacement.
What maintenance intervals are recommended for routine operation?
Vacuum pump oil replacement every 6 months; column sealing rod O-rings inspected quarterly; fluidic path cleaning with isopropanol recommended after high-salt or protein-rich sample batches.
Does LabTech provide application-specific method packages?
Yes—validated SOPs are available for PFAS (EPA 537.1), antibiotics (EU Commission Decision 2002/657/EC), and mycotoxins (AOAC 2012.01), including instrument settings, column selection, and QC acceptance criteria.
