Thermo Fisher ISQ QD Single Quadrupole Gas Chromatography-Mass Spectrometer (Used, Refurbished)

Overview

The Thermo Fisher ISQ QD is a high-performance, single quadrupole gas chromatography–mass spectrometer engineered for robustness, operational continuity, and analytical flexibility in regulated and research laboratories. Based on quadrupole mass filtering technology coupled with electron ionization (EI) and configurable chemical ionization (CI) sources, the ISQ QD delivers reliable compound identification, quantitation, and screening across environmental, pharmaceutical, food safety, and forensic applications. Its core architecture integrates a thermally stable quadrupole mass analyzer, a high-efficiency ExtractaBrite™ ion source, and a vacuum interlock system that enables source maintenance without venting the mass spectrometer—minimizing downtime and preserving calibration integrity. Designed for continuous high-throughput workflows, the ISQ QD supports fast GC ramp rates and maintains spectral fidelity even under rapid scan conditions.

Key Features

• Full Source Removal™ Technology: Enables complete, tool-free extraction of the ion source assembly while maintaining high vacuum—reducing maintenance time by >70% compared to conventional designs.
• Extended Mass Range (1.2–1100 u): Supports analysis of volatile and semi-volatile compounds, including high-molecular-weight pesticides, brominated flame retardants, and polycyclic aromatic hydrocarbons (PAHs).
• Simultaneous Full-Scan/SIM Acquisition: Delivers both qualitative confirmation and quantitative precision in a single injection—essential for compliance with EPA Method 8270, USP , and ISO 17025 workflows.
• ExtractaBrite™ Ion Source: Features optimized geometry and surface treatment to enhance ion transmission efficiency, reduce memory effects, and extend source cleaning intervals.
• Dual-Filament Electron Gun: Provides redundant emission control with independent filament current regulation—improving long-term signal stability and reducing unplanned lamp replacement events.
• Pulse-Modulated Positive/Negative Ion Chemical Ionization (PPINICI): Allows automated switching between PCI and NCI modes within one run—critical for molecular weight verification and selective detection of labile or low-ionization-efficiency analytes.
• S-Path Ion Optics: A curved ion transmission path suppresses neutral noise and stray photons, improving signal-to-noise ratio (S/N) by up to 3× over linear configurations.
• GC Compatibility: Fully integrated with Thermo’s TRACE 1300 Series GC—including split/splitless, PTV, and direct inlet options—as well as third-party GC systems via analog/digital I/O interfaces.

Sample Compatibility & Compliance

The ISQ QD accommodates diverse sample introduction methods: liquid injection (via standard or large-volume injectors), headspace analysis, solid-phase microextraction (SPME), thermal desorption (TD), purge-and-trap (P&T), and direct insertion probe (DIP/DEP). Its hardware and software architecture support audit-ready operation under GLP, GMP, and FDA 21 CFR Part 11 requirements when configured with appropriate security settings, electronic signatures, and audit trail logging in QuanLab Forms. The system meets ASTM D5845 (determination of benzene in gasoline), EPA Methods 502.2, 524.4, 8260, and 8270, and EU Directive 2009/48/EC (toy safety) testing protocols. All refurbished units undergo full functional validation per Thermo Fisher service standards—including mass calibration, resolution verification, sensitivity testing at m/z 502 (decamethylcyclopentasiloxane), and background noise profiling.

Software & Data Management

Data acquisition, processing, and reporting are managed through Thermo’s Xcalibur-based QuanLab Forms platform—a validated, workflow-driven application designed for routine QC environments. QuanLab Forms supports customizable report templates, automatic peak integration using retention time locking (RTL), internal standard normalization, and multi-level calibration curves with weighting. Optional modules include EnviroLab Forms (for EPA-compliant environmental data review) and ToxLab Forms (for toxicology screening with library matching against NIST/EPA/WHO libraries). Raw data files (.RAW) are stored in vendor-neutral format and fully compatible with third-party chemometric tools (e.g., AMDIS, Compound Discoverer). System logs—including method changes, user logins, calibration events, and instrument status—are retained with timestamped, non-erasable audit trails meeting ISO/IEC 17025 documentation requirements.

Applications

• Environmental analysis: PAHs, PCBs, organochlorine pesticides, VOCs, and emerging contaminants (e.g., PFAS precursors) in water, soil, and air matrices.
• Pharmaceutical impurity profiling and residual solvent testing per ICH Q3C guidelines.
• Food safety: Mycotoxin screening, pesticide residue quantitation, and flavor/aroma compound profiling.
• Forensic toxicology: Rapid identification of drugs of abuse, metabolites, and novel psychoactive substances (NPS).
• Polymer additive analysis: Plasticizers (e.g., phthalates), antioxidants (e.g., BHT), and flame retardants in consumer products.
• Academic research: Reaction monitoring, metabolic pathway elucidation, and small-molecule discovery in natural product chemistry.

FAQ

Is this unit factory-refurbished or dealer-refurbished?
This ISQ QD system has undergone comprehensive refurbishment by SpectraLab Scientific’s certified service engineers—including full mechanical inspection, vacuum integrity testing, detector gain calibration, and source cleaning/reconditioning per Thermo Fisher technical bulletins.
What documentation accompanies the instrument?
Each unit ships with a Certificate of Functional Verification, detailed service history log, updated firmware version report, and a 6-month limited warranty covering parts and labor for defects in materials or workmanship.
Can the system be validated for 21 CFR Part 11 compliance?
Yes—when deployed with QuanLab Forms v3.3 or later and configured with role-based access control, electronic signatures, and audit trail activation, the system meets baseline requirements for Part 11 compliance; IQ/OQ documentation packages are available upon request.
Is the TRACE 1300 GC included with column oven, injector, and detector modules?
Yes—the listed configuration includes a fully functional TRACE 1300 GC equipped with a programmable temperature vaporizing (PTV) inlet, split/splitless module, and a standard capillary column oven; detector-specific accessories (e.g., FID, ECD) are not included unless specified.
Do you offer extended warranty or service contracts?
SpectraLab Scientific provides optional 12- and 24-month extended service agreements with priority remote diagnostics, on-site preventive maintenance visits, and expedited spare parts fulfillment.
