Description
EC 4/2 NUCLEODUR C18 Gravity-SB, 5 µm is an HPLC guard column for protecting analytical main columns in liquid chromatography applications. It measures 4 mm in length with a 2 mm internal diameter and is packed with 5 µm NUCLEODUR C18 Gravity-SB stationary-phase particles. Intended for main columns with 2 mm internal diameter, the cartridge retains particulate matter and strongly retained contaminants ahead of the analytical bed, helping to maintain separation quality and extend main-column lifetime.
This article is part of HPLC columns, in HPLC columns & accessories.
The product is supplied as a pack of three pieces from manufacturer Macherey-Nagel and requires the Column Protection System guard-column holder (REF 718966) for mounting. Its EC format supports narrow-bore HPLC systems using C18 Gravity-SB reversed-phase chemistry. Laboratories performing routine analysis or method work can install the guard column between the injector and the main column as a practical, replaceable protective stage, provided the 2 mm ID match to the analytical column is observed for reliable chromatographic operation.

Questions about EC 4/2 NUCLEODUR C18 Gravity-SB, 5 µm
What is this article?
EC 4/2 NUCLEODUR C18 Gravity-SB, 5 µm 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.
