Polytech HPSE-06 Accelerated Solvent Extractor

Overview

The Polytech HPSE-06 Accelerated Solvent Extractor is an engineered platform for high-throughput, reproducible extraction of organic analytes from solid and semi-solid matrices using pressurized fluid extraction (PFE) — also widely referenced as accelerated solvent extraction (ASE®). Operating on the principle of elevated temperature and pressure to enhance solubility and mass transfer kinetics, the HPSE-06 enables rapid desorption of target compounds while minimizing thermal degradation through precise dwell-time control. Unlike conventional Soxhlet or ultrasonic methods, PFE reduces solvent consumption by up to 90%, shortens extraction time from hours to minutes per sample, and improves method robustness across heterogeneous environmental, food, and regulatory compliance workflows.

Key Features

• Six-channel parallel architecture: Simultaneous independent processing of six samples under identical thermal and pressure conditions, ensuring inter-sample comparability and throughput scalability without cross-contamination risk.
• Precision thermal management: Fully enclosed six-zone heating block with ±1 °C temperature stability across the full operating range (ambient to 210 °C), enabling method transfer between labs and long-term repeatability in regulated environments.
• Intelligent pressure-regulated fluid delivery: Dual-stage high-pressure pump system capable of delivering flow rates from 0–100 mL/min at up to 26 MPa output; automatically modulates flow based on active channel count and real-time backpressure feedback to prevent overpressurization.
• Modular extraction cell design: Eight standard cell volumes (5–120 mL) fabricated from electropolished stainless steel or corrosion-resistant alloys, with PTFE-sealed vertical loading configuration for consistent solvent percolation directionality and minimal dead volume.
• Quaternary solvent blending system: On-the-fly mixing of up to four solvents at user-defined volumetric ratios, supporting gradient elution protocols and method optimization for complex matrices such as soils, sludges, and polymer composites.
• Integrated safety architecture: Embedded pressure regulation module, redundant mechanical overpressure cutoff, and gas–liquid phase isolation barrier ensure fail-safe operation during extended unattended runs — critical for GLP-compliant laboratories.

Sample Compatibility & Compliance

The HPSE-06 is validated for use with a broad spectrum of solid-phase samples including soils, sediments, sludge, plant tissues, foodstuffs, pharmaceutical tablets, and electronic waste materials. Its operational parameters align directly with multiple internationally recognized standard methods, including but not limited to: HJ 834–2017, HJ 835–2017, HJ 782–2016, HJ 783–2016, HJ 784–2016, HJ 805–2016, HJ 703–2014, HJ 647–2013, and SN/T 2593.1–2010. These standards govern the extraction of semi-volatile organic compounds (SVOCs), organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs), phenolic compounds, and other priority pollutants in environmental monitoring and regulatory testing programs. The instrument’s hardware and firmware support audit-ready data integrity practices, including timestamped event logging and traceable parameter changes — foundational requirements for ISO/IEC 17025-accredited laboratories.

Software & Data Management

The HPSE-06 features an embedded microcontroller-based operating system with bilingual (English/Chinese) graphical interface displayed on a high-contrast LCD panel. Extraction sequences are programmed via intuitive menu navigation, with real-time visualization of temperature ramp profiles, pressure curves, solvent delivery status, and cell-level cycle progress. All operational parameters — including setpoints, actual values, alarms, and maintenance events — are stored internally with time stamps and can be exported via USB to external storage media in CSV format. While the base system does not include network connectivity or LIMS integration, its deterministic control logic and structured data output facilitate third-party automation interfaces compliant with ASTM E1384 and ISO/IEC 17025 data governance frameworks. Automated post-run nitrogen purging and solvent rinse cycles further reduce carryover risk and support multi-method batch processing under 21 CFR Part 11-aligned documentation practices.

Applications

• Environmental analysis: Extraction of PAHs, PCBs, OCPs, phthalates, and emerging contaminants from soil, sediment, and municipal sludge per EPA Method 3545A and Chinese HJ-series standards.
• Food safety testing: Recovery of pesticide residues, mycotoxins, and fat-soluble vitamins from cereals, spices, and animal feed matrices.
• Pharmaceutical quality control: Isolation of active pharmaceutical ingredients (APIs) and excipients from solid dosage forms prior to HPLC or GC-MS quantification.
• Materials science: Leaching studies of flame retardants (e.g., PBDEs) and plasticizers from polymers and electronic components in RoHS and REACH compliance screening.
• Forensic and clinical toxicology: Solid-phase cleanup and analyte enrichment from hair, tissue, or filter media prior to confirmatory analysis.

FAQ

What is the maximum allowable operating pressure during extraction?
The HPSE-06 is rated for continuous operation up to 20 MPa, with a safety-rated pump output limit of 26 MPa to accommodate transient pressure spikes during solvent introduction.
Can extraction cells be cleaned and reused?
Yes — all standard cells are constructed from electropolished stainless steel or specialty alloys and are fully autoclavable; PTFE seals are replaceable and certified for repeated exposure to aggressive solvents including dichloromethane, acetone, and acetonitrile.
Is method validation support available?
Polytech provides application notes and reference extraction protocols aligned with HJ-series and ASTM standards; users may request raw performance data (recovery %, RSD, LOD/LOQ) from third-party validation reports upon inquiry.
Does the system comply with FDA 21 CFR Part 11 requirements?
While the standalone HPSE-06 lacks built-in electronic signature or audit trail modules, its deterministic control architecture, immutable event logging, and exportable parameter history enable integration into Part 11-compliant laboratory information management systems (LIMS) when deployed within a validated IT infrastructure.
How is solvent waste managed during automated rinsing cycles?
The instrument directs spent rinse solvents to designated waste collection vessels; optional vented hood integration or secondary solvent recovery modules may be configured externally to meet local EH&S regulations.
