Description
EC 4/3 NUCLEODUR 100-5 is an HPLC guard column for protecting analytical main columns in liquid chromatography applications. The cartridge has a length of 4 mm and an internal diameter of 3 mm and is packed with NUCLEODUR 100-5 material. It is intended for main columns with 3, 4 or 4,6 mm internal diameter and requires the Column Protection System guard column holder (REF 718966). Offered as a pack of three pieces from manufacturer Macherey-Nagel, the EC 4/3 design enables simple exchange of the inlet protection segment without dismantling the full analytical column. In practice, HPLC guard columns of this type are mounted upstream of the main bed to capture particulates and strongly retained sample components before they enter the separation path. Laboratories using NUCLEODUR 100-5 main columns can pair this guard chemistry for consistent phase matching at the column inlet. The compact EC format integrates into standard HPLC systems where routine column protection is required as a replaceable consumable. This three-piece pack supports continuous laboratory workflows by supplying multiple cartridges for scheduled maintenance of the guard position.
This article is part of HPLC guard columns, in HPLC columns & accessories.

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