Chu Ding Technology HSE-12C Stainless Steel High-Capacity Solid Phase Extraction System

Overview

The Chu Ding Technology HSE-12C Stainless Steel High-Capacity Solid Phase Extraction System is an engineered vacuum-assisted sample preparation platform designed for robust, reproducible solid-phase extraction (SPE) workflows in regulated and high-throughput laboratory environments. Based on the fundamental principle of selective adsorption and elution—where analytes are retained on a solid sorbent phase while interfering matrix components pass through—the HSE-12C implements a pressure-balanced vacuum manifold architecture to ensure uniform flow control across all 12 parallel extraction channels. Unlike gravity-fed or manually aspirated SPE setups, this system maintains consistent vacuum distribution via a sealed stainless steel pressure chamber, minimizing channel-to-channel variability and eliminating flow rate drift during multi-sample processing. Its design prioritizes chemical inertness, mechanical durability, and operational repeatability—critical requirements for method transfer between QC labs, GLP-compliant residue analysis, and ISO/IEC 17025-accredited testing facilities.

Key Features

• Stainless steel (AISI 304) construction throughout the main chamber, collection base, and vacuum interface—ensuring long-term resistance to organic solvents, acids, and bases commonly used in EPA Method 500/525, AOAC 2007.01, and EN 15662 workflows.
• Integrated 10 L stainless steel collection reservoir with calibrated volume markings and drain valve—enabling bulk solvent recovery, post-extraction concentration, or direct connection to nitrogen evaporators or centrifugal concentrators.
• Vacuum-sealed manifold with dual-stage pressure regulation: primary vacuum inlet with adjustable needle valve and secondary venting port for fine-tuned flow optimization across diverse sorbent chemistries (e.g., C18, SCX, SAX, Florisil, and molecularly imprinted polymers).
• Anti-cross-contamination design featuring independent Luer-lock ports, gasketed cartridge holders, and vapor-trap–equipped vacuum lines to suppress aerosol formation and prevent carryover between sequential runs.
• Modular compatibility with standard 1 mL–20 mL SPE cartridges and disposable well plates—supporting both discrete column-based and high-density plate-based protocols without adapter kits.
• Low-profile footprint (φ250 × 250 mm) and lightweight chassis (2 kg) facilitate placement inside fume hoods, laminar flow cabinets, or automated sample prep workstations.

Sample Compatibility & Compliance

The HSE-12C accommodates aqueous, semi-aqueous, and organic liquid matrices—including wastewater, plasma, fruit juice extracts, soil leachates, and pesticide-spiked food homogenates. It supports validated methods requiring defined flow rates (e.g., ≤5 mL/min per channel per ASTM D7296-19), precise solvent switching (via timed fraction collection), and low-volume loading (as little as 0.5 mL sample per cartridge). The system conforms to structural integrity requirements outlined in ISO 17025:2017 Clause 6.4 (equipment suitability) and supports audit-ready documentation when paired with traceable vacuum gauges and calibrated collection vessels. While not intrinsically compliant with FDA 21 CFR Part 11, its mechanical operation enables integration into electronic lab notebook (ELN)–linked SOPs where manual parameter logging and signature-controlled run records satisfy ALCOA+ data integrity principles.

Software & Data Management

As a hardware-only vacuum manifold, the HSE-12C operates without embedded firmware or proprietary software. This architecture ensures full interoperability with third-party laboratory information management systems (LIMS), chromatography data systems (CDS), and digital SOP platforms. Users may document run parameters—including vacuum setpoint, elapsed time per elution step, and collection vessel identification—using standardized templates aligned with ISO/IEC 17025 Annex A.3 (recording of environmental and operational conditions). Optional accessories—such as analog vacuum gauges with NIST-traceable calibration certificates or Bluetooth-enabled digital manometers—facilitate automated data capture and CSV export for trend analysis in quality review meetings.

Applications

• Environmental monitoring: Pre-concentration of trace-level pharmaceuticals, PFAS, and endocrine disruptors from 1–10 L water samples prior to LC-MS/MS analysis.
• Food safety: Cleanup of mycotoxin extracts from cereal grains and infant formula following EN 16179:2012 and EU Commission Regulation (EC) No 401/2006.
• Pharmaceutical QA/QC: Isolation of active pharmaceutical ingredients (APIs) and genotoxic impurities from stability-indicating HPLC fractions.
• Clinical toxicology: Simultaneous purification of amphetamines, opioids, and benzodiazepines from human urine specimens under CLIA-waived workflow constraints.
• Agricultural residue testing: Multi-residue extraction of organophosphates and neonicotinoids from homogenized produce samples prior to GC-ECD or LC-QqQ quantification.

FAQ

What vacuum source is recommended for optimal performance?
A diaphragm vacuum pump capable of sustaining ≥0.08 MPa (600 Torr) absolute pressure with oil-free operation is advised to maintain chemical compatibility and minimize maintenance intervals.
Can the HSE-12C be used with 47 mm disk-based SPE formats?
Yes—when fitted with optional disk holder adapters (sold separately), the system supports polypropylene- and stainless steel–backed filtration disks for large-volume environmental sampling applications.
Is sterilization or autoclaving supported?
The stainless steel body is compatible with ethanol wiping and VHP (vaporized hydrogen peroxide) decontamination; however, autoclaving is not recommended due to elastomer seal limitations in the vacuum interface.
How is channel-to-channel flow consistency verified?
Users may perform a water-break test using calibrated graduated cylinders and stopwatch timing per ASTM D7296-19 Annex A1—measuring ±5% deviation across all 12 channels at nominal vacuum settings.
Does the system include vacuum gauge or pressure sensor?
No—vacuum monitoring requires external instrumentation; we recommend pairing with a calibrated analog Bourdon tube gauge or digital manometer with 0.01 MPa resolution.
