Thermo Fisher Surveyor MSQ Single Quadrupole Liquid Chromatography-Mass Spectrometer (Used, Refurbished)

Overview

The Thermo Fisher Surveyor MSQ is a compact, benchtop single quadrupole liquid chromatography-mass spectrometer (LC-MS) engineered for robust routine analysis in regulated and research laboratories. Built upon Thermo Scientific’s MSQ Plus platform, this system integrates a Surveyor HPLC front-end—including ASI-100 autosampler and high-pressure pumps—with a dedicated single quadrupole mass analyzer. Its core measurement principle relies on electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI), both implemented via a dual-mode, tool-free ion source capable of rapid polarity switching without hardware reconfiguration. The instrument operates under vacuum maintained by a dedicated turbomolecular pump assembly and employs a triple-right-angle M-Path ion optics architecture to minimize neutral noise and enhance signal-to-noise ratio—critical for trace-level quantitation in complex matrices such as biological fluids, environmental extracts, or pharmaceutical formulations.

Key Features

• Integrated dual-ionization capability: Simultaneous ESI and APCI support enables broad analyte coverage—from polar small molecules to moderately nonpolar compounds—without source replacement or flow splitting.
• M-Path ion source design: Reduces background interference through geometric filtering, improving detection sensitivity and reproducibility across diverse LC gradients and mobile phases.
• Ion Bright™ detector: A patented electron multiplier system delivering extended dynamic range (>5 orders), low dark current, and consistent response for both positive- and negative-ion modes.
• Square RF lens assembly: Optimized ion transmission efficiency across the full 17–2000 m/z range, supporting high-resolution full-scan acquisition at up to 12,000 amu/sec.
• Titanium alloy sampling cone: Chemically resistant and thermally stable, enabling reliable operation with high-salt, phosphate-buffered, or ion-pairing mobile phases—common in peptide mapping or acidic compound analysis.
• Patented cone cleaning system: Minimizes downtime by allowing in situ desorption of non-volatile residues without disassembly.
• FastLoc sample introduction: Maintains sensitivity at flow rates up to 2 mL/min, facilitating direct coupling with standard HPLC and UHPLC systems without flow splitting or post-column dilution.

Sample Compatibility & Compliance

The Surveyor MSQ demonstrates exceptional tolerance for challenging sample types, including those containing high concentrations of salts, phosphates, or ion-pairing reagents—conditions that typically compromise conventional LC-MS interfaces. Its robust source design permits uninterrupted operation with aqueous-rich or highly organic eluents, and its heated capillary (operable from ambient to 650 °C) ensures efficient desolvation across wide polarity ranges. From a regulatory standpoint, the system is fully compatible with validated workflows adhering to USP , ASTM D7593, and ISO/IEC 17025 requirements. When operated with Xcalibur v2.3 or later and configured with audit-trail-enabled user management, it satisfies key elements of FDA 21 CFR Part 11 for electronic records and signatures in GxP environments. Routine calibration and performance verification follow Thermo’s documented procedures aligned with GLP and cGMP laboratory practices.

Software & Data Management

Data acquisition and processing are managed through Thermo Scientific Xcalibur software (v2.0–v2.8, depending on refurbishment configuration), which provides full control over scan functions—including full-scan, selected ion monitoring (SIM), and enhanced product ion (EPI) modes—as well as real-time polarity switching and programmable cone voltage ramping. Raw data files (.raw) are stored in a vendor-neutral format compatible with third-party quantitation platforms (e.g., TraceFinder, Compound Discoverer). Instrument method files include embedded calibration parameters and QC checklists, supporting automated system suitability testing. All refurbished units undergo firmware validation and receive updated security patches where applicable; optional remote diagnostics and secure data export modules are available upon request.

Applications

This system is routinely deployed in quality control laboratories for residual solvent analysis, extractable/leachable studies, and stability-indicating assays per ICH Q2(R2). In environmental labs, it supports EPA Method 8270D-compliant semi-volatile organic compound screening. Academic and contract research facilities utilize its rapid polarity-switching capability for untargeted metabolite profiling in plasma or urine, while food safety labs apply it to pesticide residue screening using multi-residue SIM methods. Its compatibility with high-flow HPLC makes it suitable for preparative fraction analysis and reaction monitoring in synthetic chemistry workflows.

FAQ

Is this unit fully refurbished and tested prior to shipment?
Yes. Each Surveyor MSQ undergoes comprehensive functional verification—including mass axis calibration, sensitivity assessment using caffeine and reserpine standards, vacuum integrity testing, and source contamination inspection—per Thermo’s OEM service protocols.
