Vanquish Flex UHPLC systems - Dependably different. Lab ready.

Significance of the topic

Liquid chromatography (LC) and ultra-high-performance liquid chromatography (UHPLC) remain central to pharmaceutical development, biotherapeutic characterization, environmental and food testing, and quality control in manufacturing. Modern UHPLC platforms that combine high precision, broad detector compatibility, automation and biocompatible fluidics accelerate method development, improve data confidence for trace analysis, and reduce instrument downtime — all critical to high-throughput regulated and research laboratories.

Objectives and overview of the brochure

The document presents the Thermo Scientific Vanquish Flex UHPLC family as a flexible, robust, and user-friendly platform intended to address diverse UHPLC needs. It highlights system features that support routine and advanced LC and LC–MS workflows, method development automation, high-throughput and tandem configurations, and biocompatible operation for challenging eluents and biomolecules. The brochure positions the Vanquish Flex series as integrable with major chromatography software and Thermo Fisher mass spectrometers.

Methodology and approach described

The brochure summarizes engineering and workflow choices rather than experimental protocols. Key methodological themes include:

• Modular hardware: multiple pump types (to match throughput or advanced workflows) and detector options to accommodate normal and reversed-phase separations.
• Biocompatible fluid path design: corrosion-resistant materials, high-salt eluent compatibility, and minimized metal ion leaching for improved biomolecule integrity and column life.
• Smart fluidic features: SmartInject injection to avoid pressure transients, vial-bottom sample aspiration to maximize low-volume sample use, and torque-controlled Viper TQ fittings to ensure reliable leak-free connections.
• Automation and software integration: automated method scouting (multi-column and eluent scouting), Chromeleon CDS integration with ChromSword or S-Matrix Fusion QbD for Analytical Quality by Design (AQbD) workflows, and SII for Empower/OpenLab compatibility.
• High-throughput architectures: Duo systems with independent channels and Tandem LC to maximize detector/MS utilization and reduce idle time.

Used instrumentation

The brochure lists and describes the following instruments and modules as part of the Vanquish Flex ecosystem or compatible peripherals:

• Vanquish Flex UHPLC components (autosampler, pumps, switching valves, sample hub)
• Vanquish Solvent Monitor
• Vanquish User Interface (glove-enabled touch display)
• Viper TQ UHPLC torque-controlled fingertight fittings
• SmartInject Technology (proprietary injection method)
• Detectors: Vanquish Diode Array Detector (DAD) HL and FG, Variable Wavelength Detector (VWD), Fluorescence Detector (FLD), Refractive Index Detector (RID), Charged Aerosol Detector (CAD) P Series
• Mass spectrometers: ISQ EM/ISQ EC single quadrupoles and Orbitrap-class high-resolution instruments (e.g., Orbitrap Excedion Pro)
• Automation accessories: Vanquish Loader, Vanquish Sample Hub, robotic movers
• Software: Chromeleon CDS, ChromSword Chromeleon Connect, S‑Matrix Fusion QbD, TraceFinder, Xcalibur; SII support for Waters Empower 3 and Agilent OpenLab.

Main results and discussion (key performance claims)

Although the brochure reports vendor performance rather than peer-reviewed data, the main claims and evidence highlights are:

• Enhanced retention time precision and improved column lifetime through SmartInject by eliminating pressure drops at injection, supported by pressure and UV traces showing reduced post-injection transients.
• Automated method scouting enabling sequential evaluation of up to six column chemistries and broad eluent scouting to accelerate method development using sub-2 µm columns.
• Wide detector coverage: CAD provides near-universal detection for non-chromophoric analytes at sub-nanogram sensitivity, DAD/FLD/RID provide established optical detection modes, and MS options deliver high sensitivity and selectivity for LC–MS quantitation and identification.
• Throughput gains: Duo systems can double sample throughput by providing two independent channels; Tandem LC improves MS utilization and claims an average ~30% productivity increase relative to single-channel LC.
• Operational robustness: vial-bottom detection for low-volume samples, torque-limited Viper TQ fittings rated for >300 cycles, solvent/waste monitoring to prevent dry runs and spills, glove-compatible touch UI, and long-life low-maintenance valves.
• Sustainability note: product family certified with ACT Ecolabel by My Green Lab, and secondary/tertiary packaging is PVC/PS-free.

Benefits and practical applications

The Vanquish Flex UHPLC platform is presented as suitable across multiple laboratory contexts:

• Pharmaceutical R&D and QA/QC: rapid method development, robust retention-time control, and MS compatibility for drug substance and metabolite profiling.
• Biotherapeutic characterization: biocompatible fluidics and high-salt eluent compatibility for aggregate and size-exclusion analyses (SEC), with extended column lifetimes for high-injection campaigns.
• Food and environmental testing: CAD and MS sensitivity coupled with automated scouting allow broad-residue screening and trace quantification even for non-chromophoric analytes.
• High-throughput and regulated labs: Duo and Tandem configurations, solvent monitoring, and instrument automation reduce instrument idle time and support compliance via Chromeleon CDS integration.

Future trends and opportunities for application

Key directions where platforms like Vanquish Flex can add value include:

• Deeper integration of AQbD and automated method optimization pipelines to reduce human intervention during method transfer and validation.
• Broader adoption of universal detectors (CAD) together with HRMS to improve non-target screening and workflow robustness for complex matrices.
• Expansion of multi-dimensional and online sample-prep workflows (2D-LC, online SPE) for enhanced separations of complex biologics and impurities.
• Increased laboratory automation—robotic sample handling and instrument scheduling—to drive throughput and reproducibility in regulated environments.
• Continued material and packaging sustainability improvements aligned with laboratory environmental certification programs.

Conclusion

The Vanquish Flex UHPLC family positions itself as a modular, high-performance solution for laboratories that require flexible detection choices, robust biocompatible fluidics, and streamlined method development workflows. Its features—SmartInject, vial-bottom aspiration, torque-controlled fittings, broad detector compatibility including CAD and MS, and software integration—address common bottlenecks in throughput, method transfer, and reliable trace-level analysis. For laboratories prioritizing automation, regulatory compliance and reduced total cost of ownership, the platform offers tangible operational advantages, with notable opportunities for future expansion into automated AQbD workflows and advanced 2D-LC applications.
