Description
Replacement ferrule > 2 µm for holder 718966 is a specialised PEEK ferrule intended for HPLC columns with particle sizes greater than 2 µm. It is designed for the Column Protection System guard column holder (REF 718966) and provides a dependable seal in analytical chromatography setups using conventional particle packings. The product is supplied as a pack of five pieces, so laboratories can stock consumable fittings for regular maintenance of guard column assemblies that protect analytical columns from particulates and matrix residues. Manufactured from PEEK, the ferrule offers mechanical stability and solvent compatibility suited to everyday HPLC mobile phases and operating conditions. Used with the matching CPS holder from manufacturer Macherey-Nagel, it supports EC-format guard columns as part of the Column Protection System. Keeping dedicated ferrules for packings above 2 µm helps maintain leak-free connections and consistent system performance during method work. Installation is straightforward alongside the holder’s capillaries and tools, making this pack a practical spare for chromatography laboratories performing routine guard cartridge changes.
This article is part of HPLC fittings, tubing & inline filters, in HPLC columns & accessories.

Questions about Replacem. ferrule > 2 µm f. holder718966
What is this article?
Replacem. ferrule > 2 µm f. holder718966 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC fittings, tubing & inline filters, inside HPLC columns & accessories, in Chromatography equipment.
HPLC fittings and tubing are numbered by bore. A wide bore after the column broadens the peaks. Finger-tight and wrench fittings, and stainless against PEEK, are different pressure ratings. An inline filter is the last screen before the column, and it clogs on purpose so the column does not.
An HPLC column is a tube packed, or coated, with a stationary phase. The sample is carried through it by a liquid, and the compounds leave at different times. The phase, the particle size, the length and the internal diameter decide the separation. A guard column is a short sacrificial piece in front of the analytical column. Fittings and tubing have a bore that either preserves the peak or smears it. Compound names follow IUPAC. Data are on PubChem. Method grades often cite the European Pharmacopoeia or USP.
