Description
EC 4/3 NUCLEOSIL 100-5 is an HPLC guard column (pre-column) intended to protect analytical HPLC columns from particulates and sample contaminants. The cartridge has a length of 4 mm and an internal diameter of 3 mm and is packed with the NUCLEOSIL 100-5 phase. It is designed for use with main columns of 3, 4 or 4,6 mm internal diameter and requires the Column Protection System guard-column holder (REF 718966) for installation. Supplied as a pack of three pieces from manufacturer Macherey-Nagel, these short EC cartridges help extend the working life of the analytical column, support stable retention and preserve peak shape in routine HPLC work. NUCLEOSIL 100-5 is a widely established silica-based packing used across many reversed-phase and normal-phase methods. Matching the guard chemistry to the main column keeps selectivity consistent while providing an economical first line of defence in method development, quality control and everyday laboratory separations that rely on NUCLEOSIL 100-5 columns.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEOSIL 100-5
What is this article?
EC 4/3 NUCLEOSIL 100-5 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.
