Waters Xevo TQ-S cronos Triple Quadrupole LC-MS/MS System (Rental Unit)

Overview

The Waters Xevo TQ-S cronos is a high-performance, triple quadrupole liquid chromatography–tandem mass spectrometry (LC-MS/MS) system engineered for robust, high-throughput quantitative bioanalysis and routine small-molecule applications. Built upon Waters’ proven StepWave ion optics and low-noise, off-axis photomultiplier tube (PMT) detector architecture, the system delivers exceptional sensitivity, reproducibility, and uptime—critical attributes for regulated laboratories operating under GLP, GMP, or ISO/IEC 17025 frameworks. Unlike legacy platforms requiring frequent recalibration or source cleaning, the Xevo TQ-S cronos integrates stable ion transmission pathways and thermally robust UniSpray and ESCi ion sources to maintain consistent signal intensity across extended acquisition sequences. Its core measurement principle relies on precursor ion selection in Q1, collision-induced dissociation (CID) in Q2 (collision cell), and product ion detection in Q3—enabling highly selective multiple reaction monitoring (MRM) with minimal chemical noise. Designed explicitly for labs balancing capital constraints with regulatory rigor, this rental-configured system includes full integration with ACQUITY UPLC and H-Class Plus LC modules, ensuring seamless method transfer and retention time stability.

Key Features

• Triple quadrupole architecture optimized for MRM quantification with 555 MRM transitions per second throughput
• StepWave ion optics delivering enhanced ion transmission efficiency and reduced in-source fragmentation
• Dual-mode ionization support: electrospray (ESI), atmospheric pressure chemical ionization (APCI), and ESCi (electrospray/chemical ionization hybrid)
• Mass range of 2–2048 m/z with unit mass resolution across full scan and MRM modes
• Compact footprint (35.6 × 60 × 93 cm) minimizing bench space requirements without compromising vacuum integrity or thermal management
• Integrated low-noise, long-lifetime PMT detector enabling sub-femtogram-level detection limits in validated assays
• Full compliance with FDA 21 CFR Part 11 requirements via MassLynx v4.2 Security Pack and waters_connect audit trail functionality

Sample Compatibility & Compliance

The Xevo TQ-S cronos supports diverse sample matrices—including plasma, serum, urine, tissue homogenates, environmental extracts, and pharmaceutical formulations—without modification to core hardware. Its modular ion source design permits rapid interchange between UniSpray (for high-sensitivity ESI), APCI (for thermally labile or low-polarity compounds), and ESCi (for broad polarity coverage in single-run analysis). All configurations adhere to ASTM D7896–21 (standard practice for LC-MS/MS bioanalysis), USP <1225> (validation of compendial procedures), and ICH M10 (bioanalytical method validation). Data integrity is enforced through role-based user access, electronic signatures, and immutable audit trails compliant with ALCOA+ principles. The system meets ISO 9001-certified manufacturing standards and carries CE marking for EU conformity.

Software & Data Management

Two primary software environments are pre-installed and validated for rental deployment: MassLynx v4.2 with TargetLynx Quantitation Extension (TL) and waters_connect Quantitative Analysis Software. MassLynx provides granular control over instrument parameters, peak integration logic, and report generation, while waters_connect offers centralized instrument monitoring, automated workflow scheduling, and LIMS interoperability via standard HL7 and ASTM E1384 interfaces. Both platforms support Skyline import/export for cross-platform method verification and integrate seamlessly with third-party tools such as SimGlycan and Compound Discoverer. All software modules include built-in calibration curve fitting (linear, quadratic, weighted least-squares), QC failure alerts, and automatic re-injection triggers based on predefined acceptance criteria.

Applications

This rental-ready LC-MS/MS platform is routinely deployed in contract research organizations (CROs), academic core facilities, and quality control laboratories performing: pharmacokinetic (PK) and toxicokinetic (TK) studies; residue analysis in food and agricultural products; impurity profiling in API synthesis; forensic toxicology screening; endogenous metabolite quantification (e.g., steroids, vitamins, neurotransmitters); and environmental contaminant monitoring (e.g., PFAS, pesticides, pharmaceuticals in wastewater). Its MRM speed and dynamic range make it particularly suitable for multiplexed assays requiring >100 analytes per run with <15% CV precision at LLOQ.

FAQ

Is the Xevo TQ-S cronos validated for GLP-compliant studies?

Yes—the system ships with IQ/OQ documentation templates aligned with ASTM E2500 and can be fully qualified per client-specific PQ protocols.
Can I use third-party columns or mobile phases with the integrated ACQUITY H-Class Plus LC?

Absolutely—Waters’ solvent compatibility matrix covers >95% of commercially available reversed-phase, HILIC, and ion-pairing chemistries.
What level of technical support is included during the rental term?

24/7 remote diagnostics, quarterly preventive maintenance visits, and priority response SLAs for critical instrument downtime are standard.
Are software updates and security patches covered under the lease agreement?

Yes—maintenance includes all certified firmware upgrades, security hotfixes, and annual re-validation packages for MassLynx and waters_connect.
Can I extend the rental period or convert to purchase mid-term?

Both options are supported: short-term leases (3–12 months) offer automatic renewal clauses, while “rent-to-own” agreements allow accumulated payments to offset final purchase price.
