AB SCIEX TripleTOF 6600 Quadrupole Time-of-Flight Mass Spectrometer

Overview

The AB SCIEX TripleTOF™ 6600 Quadrupole Time-of-Flight Mass Spectrometer is a high-performance hybrid mass spectrometry platform engineered for comprehensive qualitative and quantitative analysis of complex biological and chemical matrices. It integrates a quadrupole mass filter with a high-resolution, high-mass-accuracy time-of-flight (TOF) analyzer, enabling simultaneous acquisition of full-scan MS and data-dependent or data-independent MS/MS spectra at unit mass resolution up to 60,000 FWHM (at m/z 1,000) and sub-5 ppm mass accuracy (internal calibration). The system operates on orthogonal acceleration TOF principles, utilizing LINAC™ collision cell technology and an accelerated reflectron design to deliver exceptional ion transmission efficiency, duty cycle, and spectral fidelity—critical for deep proteomics, lipidomics, metabolomics, and biopharmaceutical characterization workflows.

Key Features

• Hybrid Q-TOF architecture combining a triple-quadrupole-style front-end with a high-resolution TOF analyzer for both targeted and untargeted analyses
• IonDrive™ Turbo V source with dual-mode electrospray (ESI) and atmospheric pressure chemical ionization (APCI) capability, optimized for robustness across flow rates from nano- to conventional LC
• DuoSpray™ and Digital PicoView™ nanospray sources for low-flow and high-sensitivity applications
• SelexION™ differential mobility spectrometry (DMS) interface compatibility for enhanced isomeric separation and background reduction
• SWATH® Acquisition technology with variable Q1 isolation windows (1–25 Da), enabling reproducible, comprehensive DIA (Data Independent Acquisition) across diverse sample complexity
• MRM^HR (High Resolution Multiple Reaction Monitoring) workflow support for selective quantitation with mass-resolved fragment detection
• Optimized QJet™ ion guide for efficient ion transmission and reduced signal loss across wide m/z ranges
• High-frequency LINAC™ collision cell delivering >20 Hz MS/MS cycle times without compromising resolution or sensitivity
• Compressed .wiff data format ensuring storage efficiency and cross-platform portability while preserving raw data integrity and audit trail compliance

Sample Compatibility & Compliance

The TripleTOF 6600 interfaces seamlessly with liquid chromatography systems operating at flow rates from 50 nL/min (nanoLC) to 1 mL/min (conventional HPLC), as well as capillary electrophoresis (CESI) platforms. It supports infusion-based workflows (e.g., MS/MS^ALL for lipid profiling) and is validated for use in regulated environments under GLP and GMP frameworks. Data acquisition and processing comply with FDA 21 CFR Part 11 requirements when used with compliant software versions (e.g., Analyst TF 1.8+ and PeakView® 2.2+), including electronic signatures, audit trails, and secure user access controls. Method validation aligns with ICH Q2(R2), USP , and ISO/IEC 17025 guidelines for analytical instrument qualification.

Software & Data Management

Instrument control and data acquisition are managed via Analyst® TF software, supporting real-time method optimization, automated calibration, and integrated SWATH® library generation. Raw data files (.wiff) are compatible with open-source and commercial informatics platforms—including ProteinPilot™, MarkerView®, MasterView™, and OneOmics™ cloud-based analytics—for label-free quantitation, pathway mapping, and multi-omics integration. All software modules maintain traceable metadata, version-controlled processing parameters, and export-ready reports adhering to MIAME and MIAPE standards. Data archiving follows ISO 16363-certified digital preservation protocols.

Applications

• Large-scale proteomics: SWATH® Acquisition enables reproducible, quantitative profiling of >10,000 proteins per run in human plasma or tissue lysates using microflow LC
• Lipidomics: Infusion-based MS/MS^ALL delivers structural annotation of glycerophospholipids, sphingolipids, and oxidized species without chromatographic separation
• Metabolomics: Single-injection XCMSPlus-enabled workflows detect and quantify >500 endogenous metabolites across polarity ranges
• Biopharmaceutical characterization: High-resolution MS/MS supports sequence variant detection, host cell protein (HCP) identification, deamidation/oxidation mapping, and intact/subunit mass analysis
• Toxicology & ADME: Detection of low-abundance drug metabolites and reactive intermediates in plasma, urine, and hepatocyte incubations using MRM^HR and IDA workflows

FAQ

Is the TripleTOF 6600 compatible with modern LC systems including UHPLC and nanoLC platforms?
Yes—the system supports direct coupling to Thermo, Waters, Shimadzu, and Eksigent LC systems across all flow regimes, with hardware-triggered synchronization and pressure-tolerant source interfaces.
Does the instrument meet regulatory requirements for pharmaceutical QC/QA laboratories?
When deployed with validated methods, compliant software configurations, and documented IQ/OQ/PQ protocols, the TripleTOF 6600 satisfies key elements of FDA 21 CFR Part 11, EU Annex 11, and ICH guidelines for analytical instrumentation in regulated bioanalysis.
What level of mass accuracy and resolution can be achieved during SWATH® Acquisition?
Internal calibration yields ≤3 ppm mass error across m/z 100–1,200; resolution remains ≥35,000 FWHM in SWATH® mode at 20 Hz acquisition speed with 10-ms MS/MS dwell time.
Can raw data files be reprocessed retrospectively with updated search algorithms or libraries?
Yes—.wiff files retain full centroided and profile-mode intensity data, enabling retrospective interrogation using newer database versions, fragmentation models, or quantitation algorithms without re-acquisition.
Is service and technical support available globally for this pre-owned system?
All units undergo full refurbishment by SCIEX-certified engineers, including vacuum system rebuild, detector replacement, and firmware/software updates; post-sale support includes remote diagnostics, on-site maintenance contracts, and application-specific training.
