Thermo Scientific™ Vanquish™ HPLC System

The Thermo Scientific™ Vanquish™ HPLC System is a comprehensive family of modular liquid chromatography platforms engineered to deliver uncompromised performance across the entire spectrum from routine high-performance liquid chromatography (HPLC) to ultra-high-performance liquid chromatography (UHPLC). Designed for maximum uptime, reproducibility, and seamless integration into regulated environments, the Vanquish series is a cornerstone technology in pharmaceutical quality control (QC), biopharmaceutical characterization, and advanced research laboratories.

System Architecture & Core Specifications

The system’s flexibility stems from its modular design, allowing users to configure systems tailored to specific pressure and throughput needs, ranging from the workhorse Vanquish Core to the ultra-high-pressure Vanquish Neo.

• Solvent Delivery System: The heart of the system is its high-pressure binary pump technology. Depending on the series, operating pressures range from 700 bar​ (Core) to 1500 bar​ (Horizon, Neo), enabling the use of sub-2-micron particle columns for superior resolution and speed. Key innovations include SmartFlow technology, which automatically compensates for solvent compressibility, ensuring highly accurate flow rates (e.g., 0.001–10 mL/min range) and precise gradient formation critical for LC-MS applications.

• Autosampler (Split Sampler Series): Designed for high throughput and minimal carryover, the Vanquish autosampler employs a "split" needle design and an advanced multi-solvent wash station. This configuration achieves exceptionally low carryover (typically <0.05%), which is vital for sensitive bioanalytical assays. It supports precise injection volumes from nanoliters to over 100 µL and offers thermostatted sample tray options for handling thermally labile compounds.

• Column Oven & Compartment: The column compartment provides precise temperature control from sub-ambient (with optional cooling) up to 110–120°C. It features active preheating/cooling and forced-air circulation to maintain a uniform temperature profile (±0.1°C), ensuring consistent retention times and method transferability between HPLC and UHPLC conditions.

• Detection Suite: The platform integrates seamlessly with high-speed detectors, including the Vanquish Diode Array Detector (DAD) with fast acquisition rates for capturing narrow UHPLC peaks, as well as fluorescence (FLD), charged aerosol (CAD), and mass spectrometers for comprehensive analysis.

Key Performance & Operational Advantages

• Tiered Performance Portfolio: The Vanquish family is strategically segmented. The Vanquish Core​ (700 bar) serves as a dependable workhorse for routine QC, while the Vanquish Flex​ (1000 bar) and Horizon/Neo​ (1500 bar) systems push the boundaries of UHPLC for high-resolution separations and nano-/capillary-flow LC-MS workflows.

• Viper Connection Technology: A defining feature is the use of Dionex Viper​ fingertight fittings. These zero-dead-volume connections eliminate traditional ferrules and unions, drastically reducing system dispersion and preserving peak efficiency when scaling methods between different column dimensions or system pressures.

• Software & Compliance: The system is fully controlled by Thermo Scientific’s Chromeleon Chromatography Data System (CDS). This powerful software provides complete instrument control, data processing, and robust compliance features for GLP/GMP environments, including full audit trails, electronic signatures, and eWorkflows for automated method development and validation.

Application Versatility

The Vanquish system excels in the most demanding analytical workflows. In pharmaceutical development, it is used for stability-indicating assays and impurity profiling of APIs. Its biocompatible flow path options make it ideal for characterizing proteins, peptides, and oligonucleotides in biopharmaceuticals. Furthermore, its high sensitivity and robustness are leveraged in food safety and environmental monitoring for detecting trace-level contaminants.

In summary, the Thermo Scientific Vanquish HPLC System represents a future-proof investment in liquid chromatography. By combining extreme pressure capabilities, intelligent fluidics with Viper technology, and deep software integration via Chromeleon CDS, it provides laboratories with a single platform capable of addressing both current and future challenges in analytical science, from routine testing to cutting-edge research.
