YiYao Tech E3 Universal Organic Sample Preparation System

Overview

The YiYao Tech E3 Universal Organic Sample Preparation System is a fully integrated, high-throughput platform engineered for trace-level organic analysis in regulated and research-intensive laboratories. Built upon a modular architecture, the E3 implements sequential and parallel solid-phase extraction (SPE), solvent evaporation under inert gas, and post-extraction filtration/transfer — all within a single instrument footprint. Its core measurement and process logic follows standardized liquid handling and vacuum-assisted SPE protocols compliant with ISO 17025–aligned workflows. Unlike conventional benchtop SPE manifolds or standalone concentrators, the E3 executes end-to-end sample preparation — from crude extract to instrument-ready 2 mL autosampler vials — without manual intervention. This eliminates inter-operator variability, reduces hands-on time by >90%, and enforces procedural consistency across batches, making it suitable for GLP, ISO/IEC 17025, and FDA-regulated environments where auditability and repeatability are mandatory.

Key Features

• Fully Integrated Workflow Engine: Combines SPE conditioning, loading, washing, elution, nitrogen-assisted concentration, membrane filtration, and precise 2 mL vial dispensing in one automated sequence.
• Parallel 56-Position Processing: Simultaneous SPE processing across all 56 samples — not sequential column-by-column — enabling true batch throughput scalability for screening applications.
• Disposable Tip-Based Liquid Handling: All liquid transfers performed via single-use polymer tips; no internal tubing, valves, or pumps contact sample or solvents, eliminating carryover, adsorption, and cross-contamination risks.
• Multi-Format SPE Compatibility: Accommodates standard 1 mL, 3 mL, and 6 mL SPE cartridges as well as syringe-style membrane filters (e.g., PTFE, nylon, PVDF), supporting method flexibility without hardware reconfiguration.
• Intelligent Endpoint Detection: Real-time pressure and flow monitoring during concentration, coupled with programmable endpoint criteria (e.g., residual volume, time, or pressure threshold), ensures reproducible final volumes (±5% CV).
• Human-Centric Interface: Motorized 10.1″ HD touchscreen with 180° rotation, embedded voice command support with domain-specific vocabulary (e.g., “start pesticide method”, “pause run”), and secure remote access via iOS/Android app with role-based authentication.

Sample Compatibility & Compliance

The E3 handles complex biological, environmental, and food matrices including plasma, urine, tissue homogenates, soil extracts, wastewater, and fruit juice supernatants. It supports both reversed-phase (C18, C8), mixed-mode (MCX, MAX), and ion-exchange sorbents. All wetted components — including tip racks, vial carriers, SPE plate holders, and solvent reservoirs — are constructed from chemically resistant PP, PTFE, and borosilicate glass, ensuring compatibility with aggressive solvents (e.g., DCM, acetone, 0.1% formic acid in acetonitrile). The system complies with ISO 17025 documentation requirements through built-in electronic logbooks, user action timestamps, and optional video recording of critical steps (e.g., elution, filtration). Audit trails meet ALCOA+ principles and support 21 CFR Part 11 readiness when paired with validated LIMS integration.

Software & Data Management

Controlled by YiYao’s proprietary PrepSuite™ v4.2 software, the E3 enables method library management, parameter locking per SOP, and version-controlled protocol deployment. Each run generates a structured metadata file (.xml/.csv) containing instrument state logs, sensor readings, timing events, and operator ID. Raw data export supports direct ingestion into Chromatography Data Systems (CDS) such as Thermo Chromeleon, Waters Empower, or Agilent OpenLab. Optional integration with laboratory information management systems (LIMS) is available via ASTM E1578-compliant API endpoints. Software validation packages (IQ/OQ/PQ documentation) and electronic signature modules are provided for GxP environments.

Applications

• Food Safety Testing: Multi-residue analysis of pesticides (e.g., organophosphates, neonicotinoids), veterinary drugs (e.g., fluoroquinolones, sulfonamides), and mycotoxins in cereals, dairy, and produce.
• Environmental Monitoring: Extraction and cleanup of PAHs, PCBs, phthalates, and PFAS from soil, sediment, surface water, and wastewater effluents per EPA Methods 3535A, 3546, and ISO 18856.
• Forensic Toxicology: High-recovery isolation of opioids, stimulants, benzodiazepines, and synthetic cannabinoids from whole blood and urine prior to LC-MS/MS quantification.
• Pharmaceutical & Biomedical Research: Plasma protein binding studies, metabolite profiling in ADME assays, and biomarker enrichment from serum or CSF.
• Contract & Reference Laboratories: Scalable, auditable sample prep for ISO/IEC 17025-accredited testing services requiring full traceability and minimal manual touchpoints.

FAQ

Does the E3 support method validation per ICH Q2(R2) guidelines?
Yes — the system’s deterministic liquid handling, calibrated endpoint detection, and comprehensive audit trail generation support validation of precision, accuracy, and robustness for SPE-based methods.
Can legacy SPE methods be directly ported to the E3 platform?
Most conventional cartridge-based protocols can be adapted using PrepSuite™’s method editor; minor optimization of flow rates and vacuum levels may be required for equivalent recovery.
Is the video recording module compliant with GLP Annex 11 requirements?
Video capture is timestamped, digitally signed, and stored in an encrypted archive folder; optional integration with validated eDMS platforms enables long-term retention per GLP archiving rules.
What maintenance intervals are recommended for routine operation?
Daily tip waste bin emptying and weekly cleaning of the SPE plate docking station; annual calibration of pressure sensors and gas flow controllers is advised.
How is solvent compatibility verified for new extraction protocols?
Wetted material datasheets (PP, PTFE, glass) are provided with chemical resistance tables covering >120 common solvents; compatibility verification testing is supported by YiYao’s application lab upon request.
