Description
EC 4/2 NUCLEODUR C18 ISIS is an HPLC guard column with 1,8 µm particles, built to protect analytical main columns during liquid chromatography. The cartridge has a length of 4 mm and an internal diameter of 2 mm, matching main columns with 2 mm ID. Packed as three pieces per pack, the guard columns intercept particulates and strongly retained sample constituents before they reach the analytical bed, helping preserve column lifetime and peak integrity. The NUCLEODUR C18 ISIS reversed-phase chemistry supports selective C18 separations in pharmaceutical, environmental and research HPLC methods. These cartridges from manufacturer Macherey-Nagel require the Column Protection System guard column holder (REF 718966) for correct mounting. The EC 4/2 format integrates into standard EC column setups and is intended specifically for 2 mm ID main columns. Used as specified, the guard column contributes to stable back-pressure behaviour and reproducible chromatography by shielding the main packing from matrix load and mechanical stress in routine analytical workflows.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR C18 ISIS, 1.8 µM
What is this article?
EC 4/2 NUCLEODUR C18 ISIS, 1.8 µM is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC guard columns, inside HPLC columns & accessories, in Chromatography equipment.
A guard column is a short column of the same phase as the analytical column, placed in front of it to catch particles and compounds that would stick forever. It is meant to be replaced. A guard of a different phase changes the separation. The holder and the cartridge are often separate parts.
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.
