Description
EC 4/2 NUCLEODUR 100-3 C18 ec is an HPLC guard column for protecting analytical main columns in reversed-phase liquid chromatography. It has a length of 4 mm and an internal diameter of 2 mm, and is intended for use with main columns of 2 mm ID. The NUCLEODUR 100-3 C18 ec packing is a fully endcapped C18 phase on spherical silica, matching the chemistry of corresponding analytical columns so that selectivity remains consistent when the guard is installed upstream. Supplied as a pack of 3 pieces, the cartridges require the Column Protection System guard column holder (REF 718966) for correct mounting. Used as a disposable front-end filter, the guard retains particulates and strongly retained matrix components before they reach the main bed, helping to preserve efficiency and extend column lifetime in routine and method-development work. This EC-format guard column from manufacturer Macherey-Nagel is a practical choice for laboratories running narrow-bore 2 mm ID HPLC systems that need reliable column protection without changing the primary separation phase.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR 100-3 C18 ec
What is this article?
EC 4/2 NUCLEODUR 100-3 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.
