PEEK (polyetheretherketone) ferrules and fittings are crucial components in High-Performance Liquid Chromatography (HPLC) systems, primarily used for making leak-tight connections between tubing and other system components. Their inertness, biocompatibility, and ability to withstand high pressures and various solvents make them ideal for HPLC applications, particularly when dealing with sensitive biological compounds or when minimizing system contamination is paramount. Here's a more detailed look at their applications:1. Leak-Free Connections: PEEK ferrules and fittings are designed to create a secure seal, preventing leaks that can compromise the integrity of the separation and lead to inaccurate results. 2. Chemical Resistance: PEEK is highly resistant to a wide range of solvents and mobile phases commonly used in HPLC, ensuring that the fittings don't degrade or contaminate the sample. 3. Biocompatibility: PEEK's biocompatibility is crucial when working with biological samples like proteins, peptides, and other biomolecules, minimizing sample interactions and ensuring accurate analysis. 4. High-Pressure Handling: PEEK fittings can withstand the high pressures commonly used in HPLC and UHPLC (Ultra High-Pressure Liquid Chromatography) systems, making them suitable for a variety of applications. 5. Ease of Use: Many PEEK fittings are designed for finger-tightening, simplifying installation and reducing the risk of over-tightening or damaging the components. 6. Applications in Various HPLC Systems:

• General HPLC:PEEK fittings are used for connecting columns, detectors, pumps, and other modules within the HPLC system. 
• LC-MS:In Liquid Chromatography-Mass Spectrometry, PEEK's inertness is particularly important to minimize ion suppression and ensure accurate mass measurements. 
• Biomolecule Separation:PEEK is widely used for separating and analyzing proteins, peptides, and other biomolecules due to its biocompatibility. 

Designed for secure liquid-tight connections Adapters for semi-rigid tubing are color-coded by tubing size for easy identification. A two-piece nut and ferrule system provides a liquid-tight connection and withstands pressures up to 500 psi.

High pressure fittings offer extra durability. They are more robust to higher temperatures, solvent exposure and overtightening than standard peek fittings. They are available in a variety of dimensions, all with built-in ferrules.
