Thermo Scientific Orbitrap Ascend MultiOmics Tribrid Mass Spectrometer

Overview

The Thermo Scientific Orbitrap Ascend MultiOmics Tribrid Mass Spectrometer is a next-generation hybrid platform engineered for high-resolution, high-mass-accuracy multi-omics analysis. Built upon the proven Tribrid architecture—integrating a quadrupole mass filter, linear ion trap (LIT), and Orbitrap mass analyzer—the system delivers simultaneous high-sensitivity detection across broad m/z ranges, with resolution up to 500,000 FWHM at m/z 200 and sub-ppm mass accuracy in both MS and MS/MS modes. Its core measurement principle combines electrospray ionization (ESI) or nanoelectrospray ionization (nanoESI) with parallelized acquisition strategies—including real-time search (RTS), data-independent acquisition (DIA), and intelligent data-dependent acquisition (iDDA)—to enable deep, quantitative profiling of peptides, metabolites, lipids, glycans, and intact proteins from complex biological matrices. Designed specifically for laboratories pursuing integrated omics workflows, the Ascend MultiOmics edition supports seamless transition between bottom-up proteomics, top-down proteoform analysis, untargeted metabolomics, and cross-omics correlation without hardware reconfiguration.

Key Features

• Tribrid architecture with dual-pressure linear ion trap (LIT) and ultra-high-field Orbitrap analyzer (up to 500,000 resolution at m/z 200)
• Extended mass range: Orbitrap detection up to m/z 16,000; LIT and quadrupole isolation up to m/z 8,000
• Sub-100 Da isolation window capability (down to m/z 5 in LIT, m/z 100 in quadrupole) for high-selectivity precursor selection
• Non-denaturing MS option supporting native MS workflows, including intact protein complexes and membrane protein assemblies
• Advanced ion optics with enhanced transmission efficiency across low- and high-m/z regimes
• Integrated RF-driven collision cell enabling optimized HCD, CID, and ETD fragmentation in a single acquisition cycle
• Automated calibration and lock-mass correction using internal or external reference ions for long-term mass stability

Sample Compatibility & Compliance

The Orbitrap Ascend MultiOmics Tribrid MS accepts samples introduced via standard ESI sources, nanoESI emitters, and optional microflow or chip-based interfaces. It accommodates diverse sample types—from crude cell lysates and plasma digests to purified exosomes, extracellular vesicles, and native protein preparations. The system complies with international analytical standards including ISO/IEC 17025 for testing laboratories and supports GLP/GMP-aligned operation through audit-trail-enabled software (Thermo Scientific Chromeleon CDS v7.3+). Data integrity features meet FDA 21 CFR Part 11 requirements, including electronic signatures, user role-based access control, and immutable raw data storage. Method validation protocols align with ICH Q2(R2) and USP guidelines for analytical instrument qualification.

Software & Data Management

Controlled by Thermo Scientific Compound Discoverer 3.3 and Proteome Discoverer 2.5+, the platform provides end-to-end workflow automation—from peak detection and alignment to statistical filtering, pathway mapping, and multi-omics integration. Raw data files (.raw) are natively compatible with open-source tools including MaxQuant, Skyline, XCMS Online, and MZmine 3. All acquisition methods, processing parameters, and metadata are stored in structured XML format with version-controlled templates. Integrated cloud-ready architecture enables secure remote monitoring, centralized method deployment, and scalable data archiving via Thermo Fisher Connect. Audit trails record every user action, parameter change, and calibration event, ensuring full traceability for regulatory submissions.

Applications

• Deep quantitative proteomics: label-free, TMT, and SILAC-based workflows with >10,000 protein groups per run
• Intact protein and protein complex characterization under native conditions (e.g., ribosomes, chaperonins, antibody–drug conjugates)
• Untargeted metabolomics with accurate mass screening and in silico spectral library matching
• Multi-attribute monitoring (MAM) for biopharmaceuticals, including charge variant profiling, deamidation, oxidation, and glycoform quantitation
• Structural proteomics: HDX-MS, cross-linking MS (XL-MS), and native top-down sequencing
• Single-cell and spatial omics coupling via integration with microfluidic sample introduction systems

FAQ

Does the Orbitrap Ascend MultiOmics Tribrid support native mass spectrometry?
Yes—when equipped with the Non-Denaturing MS option, it maintains high transmission and resolution for intact protein complexes up to ~1.5 MDa.
What software licenses are required for multi-omics data integration?
Compound Discoverer 3.3 (for metabolomics/lipidomics) and Proteome Discoverer 2.5+ (for proteomics) are included; additional modules for glycomics or structural biology require separate activation.
Is the instrument compliant with 21 CFR Part 11 for regulated environments?
Yes—Chromeleon CDS v7.3+ provides full electronic signature support, audit trail generation, and secure user authentication as validated per Thermo Fisher’s IQ/OQ/PQ documentation.
Can the system perform real-time database searching during acquisition?
Yes—Real-Time Search (RTS) functionality enables on-the-fly peptide identification and dynamic exclusion updates during LC-MS/MS runs.
What maintenance intervals are recommended for optimal performance?
Ion source cleaning every 72 hours of operation; Orbitrap vacuum system inspection every 6 months; annual preventive maintenance by Thermo-certified engineers.
