Description
EC 4/3 NUCLEODUR 100-5 C18 ec is an HPLC guard column intended to protect analytical main columns during liquid chromatography. The cartridge measures 4 mm in length with an inner diameter of 3 mm and is packed with the NUCLEODUR 100-5 C18 ec stationary phase. Supplied as a pack of three pieces, it is designed for use with main columns of 3, 4 or 4,6 mm internal diameter. Installation requires the Column Protection System guard-column holder (REF 718966), ensuring a secure, low-dead-volume connection in the flow path. By capturing particulate matter and strongly retained sample components before they reach the analytical bed, the guard column helps maintain peak shape, retention stability and overall system performance. This EC-format precolumn from manufacturer Macherey-Nagel integrates readily into standard HPLC setups that already employ matching NUCLEODUR C18 ec chemistry, supporting routine method transfer and consistent separation quality in analytical laboratories.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODUR 100-5 C18 ec
What is this article?
EC 4/3 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.
