Description
EC 4/3 NUCLEODUR 300-5 C18 ec is an HPLC guard column designed to shield analytical main columns during liquid chromatography. Measuring 4 mm in length with a 3 mm internal diameter, it is specified for main columns of 3 mm, 4 mm or 4,6 mm ID. The packing uses the NUCLEODUR 300-5 C18 ec stationary phase, an endcapped C18 material for reversed-phase separations where matrix load and particulates threaten column performance. Each pack contains three cartridges and requires the Column Protection System guard column holder (REF 718966) for correct mounting. Installed ahead of the analytical column, the guard bed captures strongly retained species and debris, supporting stable backpressure, peak shape and longer main-column service life. This EC-format precolumn from manufacturer Macherey-Nagel suits pharmaceutical, chemical and research HPLC workflows that employ standard analytical diameters. The short bed length limits added dead volume while delivering practical protection in everyday method use.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODUR 300-5 C18 ec
What is this article?
EC 4/3 NUCLEODUR 300-5 C18 ec 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.
