Thermo Fisher Vanquish™ C18 UHPLC Column

Overview

The Thermo Fisher Vanquish™ C18 UHPLC Column is an engineered reversed-phase analytical column designed specifically for use with the Vanquish Ultra-High Performance Liquid Chromatography (UHPLC) platform. Built upon fully porous, spherical, ultra-pure silica particles with a 2.2 µm diameter and 120 Å pore size, this column delivers high-efficiency separations under elevated backpressures—up to 1500 bar—leveraging the mechanical robustness and flow precision of Vanquish systems. Its 18% carbon load, endcapped C18 ligand chemistry, and narrow particle size distribution ensure exceptional peak shape, reproducible retention, and low batch-to-batch variability. The column operates reliably across a pH range of 2–8 and at temperatures up to 60 °C, making it suitable for method development and routine analysis in regulated environments where stability and consistency are critical.

Key Features

• Optimized for Vanquish UHPLC systems: Designed to exploit high-pressure capability (1500 bar), precise gradient delivery, and low system dispersion.
• High-resolution performance: 2.2 µm fully porous silica particles provide increased theoretical plates per meter without sacrificing column lifetime.
• Enhanced selectivity and reproducibility: Endcapped C18 phase with 18% carbon loading ensures consistent hydrophobic interactions and minimized silanol activity.
• Robust chemical stability: Stable within pH 2–8; compatible with common mobile phases including aqueous buffers, acetonitrile, and methanol.
• USP L1 classification: Meets United States Pharmacopeia requirements for C18-based reversed-phase columns used in pharmaceutical quality control and release testing.
• Validated for LC-MS compatibility: Low metal content and minimal bleed support sensitive mass spectrometric detection and long-term source cleanliness.

Sample Compatibility & Compliance

This column supports a broad range of small-molecule analytes, peptides, and polar-to-moderately hydrophobic compounds. It is routinely employed in pharmaceutical impurity profiling, stability-indicating assays, pharmacokinetic sample analysis, and natural product fractionation. The column conforms to ICH Q2(R2) guidelines for method validation parameters including specificity, linearity, accuracy, precision, and robustness. When deployed within validated workflows, it supports compliance with FDA 21 CFR Part 11, EU Annex 11, and GLP/GMP documentation requirements—particularly when paired with Vanquish systems equipped with electronic audit trails and user-access controls.

Software & Data Management

Data acquisition and method management are fully integrated via Thermo Scientific Chromeleon™ Chromatography Data System (CDS) 7.3 or later. The column is auto-recognized in Vanquish systems using embedded RFID chip technology (where applicable), enabling instrument configuration validation, column usage tracking, and lifetime logging. Chromeleon supports electronic signatures, secure user roles, and full audit trail generation—including column installation date, run count, pressure history, and maintenance events—facilitating regulatory submissions and internal quality audits.

Applications

• Pharmaceutical QC/QA: Assay, related substances, residual solvents, and dissolution testing per USP/EP monographs.
• Biopharmaceutical characterization: Peptide mapping, intact protein analysis, and excipient quantification in formulations.
• Clinical research: Therapeutic drug monitoring (TDM) and biomarker quantification in plasma, serum, and urine matrices.
• Environmental analysis: Detection of pesticides, pharmaceutical residues, and endocrine disruptors in water and soil extracts.
• Food safety: Mycotoxin screening, vitamin profiling, and adulterant identification using LC-MS/MS workflows.

FAQ

Is this column compatible with other UHPLC systems beyond Vanquish?
Yes—it is mechanically and chemically compatible with any UHPLC system capable of delivering stable flow rates up to 1 mL/min and sustaining pressures up to 1500 bar, though optimal performance is achieved on Vanquish platforms due to co-engineered hardware-software integration.
What is the recommended equilibration time between gradient runs?
For reproducible retention times, equilibrate for ≥10 column volumes using initial mobile phase conditions; typical equilibration on Vanquish systems requires <3 minutes at 0.4 mL/min.
Can this column be used for acidic or basic compounds without peak tailing?
Yes—the ultra-pure silica base and rigorous endcapping minimize residual silanol interactions, resulting in symmetrical peak shapes for both acidic and basic analytes across the specified pH range.
Does the column include an integrated RFID tag?
RFID functionality depends on packaging configuration; columns supplied as part of Vanquish Ready-to-Use kits include passive RFID chips for automatic system recognition and usage logging.
How should the column be stored long-term?
Store at room temperature in original packaging, capped, and sealed with recommended storage solvent (e.g., 80% acetonitrile/water); avoid exposure to strong acids, bases, or chlorinated solvents outside the validated pH and chemical compatibility range.
