Description
EC 4/3 NUCLEOSIL 120-3 C8 is an HPLC guard column intended to protect analytical main columns in liquid chromatography. The cartridge measures 4 mm in length with a 3 mm internal diameter and is packed with the NUCLEOSIL 120-3 C8 stationary phase for reversed-phase work based on octyl-bonded silica. Used upstream of the separation column, it helps retain particulates and strongly retained matrix components before they reach the analytical bed, supporting stable retention and peak shape over longer column lifetimes.
This article is part of HPLC columns, in HPLC columns & accessories.
Each pack contains three guard columns and is supplied by manufacturer Macherey-Nagel. The EC 4/3 format is specified for main columns with 3, 4 or 4,6 mm internal diameter and requires the Column Protection System guard column holder (REF 718966) for correct mounting with low dead volume. The compact geometry allows quick cartridge exchange during routine maintenance without changing the overall method setup. These pre-columns suit research and quality-control HPLC systems where C8 selectivity and reliable column protection are needed in everyday analytical practice.

Questions about EC 4/3 NUCLEOSIL 120-3 C8
What is this article?
EC 4/3 NUCLEOSIL 120-3 C8 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC columns, inside HPLC columns & accessories, in Chromatography equipment.
An HPLC column is specified by the stationary phase, the particle size, the length and the internal diameter. A C18, 5 µm, 150 × 4.6 mm column is a different article from a C18, 3 µm, 100 × 2.1 mm column. The smaller bore belongs on a lower flow. A column has a direction and a pH range.
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.
