Description
EC 4/2 NUCLEODUR 100-5 C18 ec is an HPLC guard column for protecting narrow-bore analytical columns in reversed-phase liquid chromatography. It offers a length of 4 mm and an internal diameter of 2 mm, and is intended for main columns with 2 mm ID. The NUCLEODUR 100-5 C18 ec packing provides a fully endcapped C18 stationary phase on spherical silica, matching the chemistry of corresponding 5 µm analytical columns so that selectivity stays aligned when the guard is fitted upstream. The product is supplied as a pack of 3 pieces and requires the Column Protection System guard column holder (REF 718966) for installation. As a replaceable front-end element, the guard retains particulates and strongly retained matrix components before they enter the main bed, supporting stable efficiency and longer analytical column lifetime in daily laboratory use. This EC-format guard column from manufacturer Macherey-Nagel is well suited to laboratories operating 2 mm ID HPLC systems that need straightforward 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 100-5 C18 ec
What is this article?
EC 4/2 NUCLEODUR 100-5 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.
Which category should I open next?
