Description
EC 4/3 NUCLEOSIL 120-5 C4 is an HPLC guard column intended to shield analytical main columns from particulates and strongly retained sample components. Measuring 4 mm in length with a 3 mm internal diameter, it is packed with NUCLEOSIL 120-5 C4 stationary phase for reversed-phase protection workflows. The short butyl-bonded bed acts as a sacrificial precolumn stage, helping preserve peak shape and extend the service life of the primary separation column. Supplied in a pack of 3 pieces, the cartridges are suitable for main columns with 3, 4 or 4,6 mm internal diameter and require the Column Protection System guard column holder (REF 718966) for installation. Offered by manufacturer Macherey-Nagel, this EC 4/3 format supports everyday HPLC method maintenance in analytical laboratories. Laboratories running C4-based separations can match guard chemistry to the main column phase, simplifying consumable selection and reducing the risk of unexpected column blockage during routine sample sequences.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEOSIL 120-5 C4
What is this article?
EC 4/3 NUCLEOSIL 120-5 C4 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.
