Overview
The Spectra Invent HX100 Fully Automated Liquid-Liquid Extractor is an engineered solution for high-throughput, standardized liquid-liquid extraction (LLE) in environmental and regulatory laboratories. Designed around the fundamental principle of partitioning analytes between two immiscible liquid phases—typically aqueous samples and organic solvents such as tetrachloroethylene or carbon tetrachloride—the HX100 delivers reproducible phase separation under controlled pneumatic agitation. Its architecture aligns with core requirements of EPA-aligned Chinese environmental standards, including HJ 637–2018 (petroleum hydrocarbons in water), HJ 1051–2019 (petroleum hydrocarbons in soil), and HJ 1077–2019 (oil mist and油烟 in stack emissions). The system operates without manual intervention across the full workflow: sample introduction, solvent addition, oscillation-assisted mass transfer, phase separation, organic layer aspiration, waste discharge, and integrated cleaning—ensuring operator safety, method traceability, and minimal solvent exposure.
Key Features
- Fully automated 3-position extraction platform enabling parallel processing of up to three samples per cycle
- Pneumatic oscillation mechanism providing consistent, non-mechanical agitation—eliminating cross-contamination risks associated with rotating or vortex-based systems
- Sealed extraction chamber with activated carbon exhaust adsorption, compliant with laboratory fume containment best practices
- Programmable extraction duration (1–1000 seconds) and adjustable oscillation intensity to accommodate diverse matrix viscosities and analyte partition coefficients
- Integrated fluid handling modules for precise reagent delivery, phase separation detection, and waste routing—each governed by calibrated peristaltic pumps and solenoid valves
- Self-cleaning protocol using solvent rinse followed by air purge, reducing carryover and supporting multi-method workflows within a single run
- Robust industrial-grade housing rated for ambient operation between –5 °C and 45 °C at 20–85% relative humidity
Sample Compatibility & Compliance
The HX100 supports aqueous sample volumes ranging from 50 mL to 1000 mL, making it suitable for both grab sampling and composite wastewater analysis. It is validated for use with tetrachloroethylene (C2Cl4) and carbon tetrachloride (CCl4)—solvents specified in HJ 637–2018 and HJ 1051–2019 for infrared quantification of total petroleum hydrocarbons (TPH). The system’s ≤5% RSD (relative standard deviation) in replicate extractions meets GLP data integrity expectations for routine environmental monitoring. While not certified to ISO/IEC 17025 out-of-the-box, its operational parameters—including timing accuracy, volume repeatability, and solvent recovery consistency—are documented per internal validation protocols aligned with CNAS-CL01:2018 requirements.
Software & Data Management
The HX100 is operated via an embedded touchscreen interface with password-protected method storage (up to 99 user-defined protocols). Each extraction event logs timestamp, sample ID, solvent type, agitation duration, and completion status—exportable via USB to CSV format for LIMS integration. Audit trail functionality records all parameter modifications and user logins, satisfying basic FDA 21 CFR Part 11 readiness criteria when deployed in GxP-constrained environments. No cloud connectivity or remote access is implemented; all data reside locally to maintain network security and regulatory boundary control.
Applications
- Determination of volatile phenols in surface and wastewater per GB/T 7490–1987 (adapted for LLE preconcentration)
- Quantification of anionic surfactants (LAS) using methylene blue active substances (MBAS) methodology
- Preparation of extracts for infrared spectrophotometric analysis of oil and grease in irrigation water (GB 5084–2021)
- Soil leachate processing prior to GC-FID or FTIR analysis for aliphatic/aromatic hydrocarbon profiling
- Exhaust gas condensate treatment in stationary source emission testing per HJ 1077–2019
FAQ
Does the HX100 support solvent switching between runs?
Yes—users may define distinct solvent types (e.g., C2Cl4, CCl4, hexane) per method, and the system automatically purges lines prior to solvent change.
Is method validation documentation provided with the instrument?
A factory performance verification report is included, covering extraction efficiency (≥95%), repeatability (RSD <5%), and timing accuracy. Full IQ/OQ documentation packages are available upon request.
Can the HX100 be integrated into an automated lab workflow with autosamplers?
The unit features dry-contact I/O ports for external trigger synchronization but does not natively interface with third-party autosamplers; integration requires custom relay logic and mechanical alignment.
What maintenance intervals are recommended?
Pneumatic tubing and solvent-wetted seals should be inspected quarterly; activated carbon filters require replacement every 200 extraction cycles or biannually—whichever occurs first.
