Overview
The Thermo Fisher TSQ Altis Triple Quadrupole Liquid Chromatography Mass Spectrometer (LC-MS/MS) is an engineered platform for high-sensitivity, high-reproducibility targeted quantitative analysis in regulated and research laboratories. Built upon proven triple quadrupole architecture, the system operates on the principle of sequential mass filtering—where Q1 selects a precursor ion, Q2 induces collision-induced dissociation (CID), and Q3 monitors one or more characteristic product ions—enabling highly selective and robust Selected Reaction Monitoring (SRM) or Multiple Reaction Monitoring (MRM) workflows. Designed for seamless integration with ultra-high-performance liquid chromatography (UHPLC) systems and automated sample preparation modules, the TSQ Altis delivers consistent performance across diverse sample matrices—from plasma and tissue homogenates to environmental water extracts and food digests—without compromising duty cycle efficiency or signal stability.
Key Features
- High-transmission ion optics optimized for low-femtogram-level detection limits in SRM mode, supporting quantitation of small molecules, peptides, lipids, and metabolites across complex biological and environmental backgrounds.
- Advanced RF-only quadrupole design in Q1 and Q3 ensures superior mass resolution and peak shape fidelity, minimizing cross-talk between co-eluting transitions.
- Heated electrospray ionization (H-ESI) and optional atmospheric pressure chemical ionization (APCI) sources provide flexible, robust ionization for thermally labile and non-polar compounds.
- Real-time, hardware-based peak width optimization dynamically adjusts dwell times per transition to maximize data point density without sacrificing cycle time—critical for UHPLC applications with sub-30-second gradients.
- Onboard calibration and autotune routines reduce manual intervention; system suitability checks are embedded within acquisition methods to support GLP/GMP-compliant operation.
Sample Compatibility & Compliance
The TSQ Altis accommodates a broad range of sample types, including but not limited to human and animal biofluids (serum, urine, CSF), tissue lysates, plant extracts, pharmaceutical formulations, drinking water, soil leachates, and polymer degradation products. Its hardware and software architecture comply with key regulatory requirements for analytical instrument qualification: IQ/OQ/PQ protocols are supported via documented installation and operational verification procedures. Data integrity features—including electronic signatures, audit trails, and user-access controls—align with FDA 21 CFR Part 11 and EU Annex 11 expectations. Method validation parameters (e.g., linearity, LOD/LOQ, precision, accuracy, matrix effects) can be assessed using built-in reporting templates compatible with ISO/IEC 17025 and ICH M10 guidelines.
Software & Data Management
Instrument control, method development, and quantitative data processing are unified under Thermo Scientific™ TraceFinder™ Software (v5.1 or later), a purpose-built application for LC-MS/MS quantitation. TraceFinder supports batch processing of large-scale studies, automated peak integration with customizable retention time windows and baseline algorithms, and integrated calibration curve fitting (linear, quadratic, weighted least-squares). All raw data files (.raw) are stored in vendor-neutral formats compliant with mzML standards. The software includes full audit trail logging for all user actions—including method edits, result reprocessing, and report generation—with timestamped, immutable records exportable for regulatory review. Optional integration with LIMS platforms (e.g., LabWare, STARLIMS) enables end-to-end sample tracking from intake to final report.
Applications
- Clinical toxicology and therapeutic drug monitoring (TDM), including immunosuppressants, antiepileptics, and opioids.
- Pharmaceutical impurity profiling and stability-indicating assays per ICH Q2(R2) guidance.
- Environmental analysis of persistent organic pollutants (POPs), per- and polyfluoroalkyl substances (PFAS), and pesticide residues in accordance with EPA Methods 1694 and 541.
- Food safety testing for mycotoxins, veterinary drug residues, and allergen markers under EU Regulation (EC) No 882/2004.
- Metabolomics and lipidomics core facility workflows requiring high-throughput, reproducible MRM panels across hundreds of analytes.
FAQ
What regulatory standards does the TSQ Altis support for data integrity?
The system meets FDA 21 CFR Part 11, EU Annex 11, and ISO/IEC 17025 requirements through electronic signature capability, full audit trail functionality, and role-based access control in TraceFinder software.
Can the TSQ Altis be used for untargeted analysis?
No—it is purpose-engineered for targeted quantitation via SRM/MRM. Untargeted workflows require high-resolution mass spectrometers such as the Thermo Scientific Q Exactive series.
Is method transfer from older TSQ platforms supported?
Yes—TraceFinder provides backward compatibility with methods developed on TSQ Vantage and TSQ Quantum Access MAX systems, including transition lists, dwell times, and collision energy settings.
What maintenance intervals are recommended for routine operation?
Ion source cleaning every 7–10 days (depending on sample load), vacuum pump oil change every 6 months, and annual preventive maintenance by certified Thermo Fisher Field Service Engineers are advised.
Does the system support isotopic dilution calibration?
Yes—TraceFinder natively supports stable isotope-labeled internal standard (SIL-IS) correction, including ratio-based quantitation, response factor calculation, and QC acceptance criteria based on IS recovery and RSD thresholds.
