Overview
The XTrust MASS-M01 Pro Solid Phase Microextraction (SPME) Instrument is an automated, benchtop platform engineered for precision, reproducibility, and regulatory compliance in sample preparation workflows. It implements the fundamental principle of solid-phase microextraction—where analytes are selectively adsorbed or absorbed onto a coated fused-silica fiber exposed to a sample matrix (liquid, headspace, or direct immersion)—followed by thermal desorption directly into a gas chromatograph (GC) or GC-MS inlet. Unlike conventional liquid–liquid extraction or solid-phase extraction, SPME eliminates solvent use, reduces sample volume requirements (as low as 1 mL), minimizes manual handling variability, and integrates sampling, extraction, concentration, and injection into a single step. The MASS-M01 Pro is specifically designed to support headspace (HS-SPME) and direct immersion (DI-SPME) modes, with dual independent extraction positions enabling parallel processing and staggered protocol execution—critical for high-throughput environmental, food safety, and pharmaceutical laboratories operating under GLP or ISO/IEC 17025 frameworks.
Key Features
- Dual independent extraction stations: Each position operates with full parameter autonomy—including temperature setpoint, agitation speed, extraction time, and fiber exposure duration—eliminating cross-interference and supporting concurrent HS-SPME and DI-SPME runs.
- Precision digital temperature control: Uniform heating up to 150 °C with ±0.5 °C stability across the entire thermal block; compatible with both 20 mL and 60 mL standard headspace vials.
- Integrated fiber aging station: Dedicated, isolated aging port with programmable nitrogen purge activation—only engaged during aging cycles—reducing nitrogen consumption by >40% compared to shared-inlet aging methods.
- Automated agitation system: Adjustable orbital shaking (0–1500 rpm) with real-time feedback control ensures consistent mass transfer kinetics across replicates.
- Intuitive software interface: PC-based control with scheduled run initiation, temperature/time logging, alarm notifications, and audit-ready event timestamps compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures.
Sample Compatibility & Compliance
The MASS-M01 Pro supports broad sample matrix compatibility—including aqueous environmental samples (surface water, wastewater, drinking water), complex biological fluids, volatile-rich food matrices (essential oils, wine, edible oils), and semi-solid pharmaceutical formulations. Its design aligns with internationally recognized SPME validation protocols outlined in ASTM D8111-21 (Standard Guide for SPME Sampling of Volatile Organic Compounds), ISO 21675:2019 (Water quality — Determination of organic compounds using SPME-GC-MS), and USP (Residual Solvents). Method validation data demonstrate mean recoveries of 92.2–107.7% for geosmin and 2-methylisoborneol (2-MIB) across triplicate analyses, with relative standard deviations (RSD) <10%, meeting acceptance criteria specified in GB/T 32470–2016 and T/JSWA 005–2021.
Software & Data Management
The instrument is controlled via XTrust SPME Control Suite v3.2—a Windows-based application supporting method library management, multi-user role assignment (admin/operator/auditor), and encrypted raw log export (CSV/Excel). All critical events—including temperature ramp profiles, agitation start/stop, fiber insertion/retraction, and nitrogen valve actuation—are timestamped and stored locally with SHA-256 hash integrity verification. Audit trails are exportable for internal QA review or external accreditation audits (e.g., CNAS, UKAS, A2LA). Optional integration with LIMS via HL7 or REST API enables automated sample ID propagation and result backfilling.
Applications
- Environmental analysis: Quantification of odorants (geosmin, 2-MIB), halogenated hydrocarbons (DB14/T 1948–2019), sulfur-containing off-flavors (T/SWSTA 0005–2021), and ether-based odorants (T/JSWA 005–2021) in water.
- Food & beverage testing: Determination of volatile aldehydes in edible oils (SN/T 3626–2013), volatile alcohols in wine (T/SATA 030–2022), and residual solvents in APIs (USP ).
- Pharmaceutical QC: SPME-GC-MS screening for organophosphorus pesticide residues (e.g., in Gentiana scabra extracts) and genotoxic impurities per ICH M7 guidelines.
- Forensic & clinical toxicology: Headspace SPME of volatile metabolites (e.g., ethanol, acetone, isopropanol) in blood or urine specimens.
FAQ
Does the MASS-M01 Pro support both headspace and direct immersion SPME modes?
Yes—each of the two independent extraction stations can be configured separately for headspace or direct immersion operation, with dedicated thermal and agitation parameters per mode.
Is fiber aging performed in situ without occupying the GC inlet?
Yes—the dedicated aging port operates independently from the GC interface; nitrogen flow is activated only during programmed aging cycles.
What vial formats are supported?
Standard 20 mL and 60 mL crimp-top or screw-cap headspace vials (with silicone/PTFE septa); no adapter kits required.
Can method files be exported for regulatory submission?
Yes—full method definitions, raw log files, and audit trails are exportable in PDF and CSV formats with embedded digital signatures for 21 CFR Part 11 compliance.
Is remote monitoring or network integration available?
Optional Ethernet connectivity enables remote status monitoring and LIMS integration via configurable API endpoints; on-site IT validation support is provided.
