Description
EC 4/2 NUCLEODUR 100-5 C8 ec is an HPLC guard column intended to protect analytical main columns in liquid chromatography. It has a length of 4 mm and an inner diameter of 2 mm, matching the geometry of 2 mm ID main columns so that particulates and strongly retained matrix components are trapped before they reach the analytical bed.
This article is part of HPLC columns, in HPLC columns & accessories.
The cartridge uses the NUCLEODUR 100-5 C8 ec stationary phase, supporting reversed-phase work based on octyl-bonded silica. Each pack contains three pieces and is supplied by manufacturer Macherey-Nagel. Installation requires the Column Protection System guard column holder (REF 718966), ensuring a secure fit in EC-format systems. This configuration suits narrow-bore HPLC methods where safeguarding sensitive 2 mm ID columns helps maintain peak shape, reduce contamination risk, and limit premature column replacement.
Typical use includes method development, routine analysis, and quality-control workflows that demand stable chromatographic performance and efficient protection of the main separation column under continuous sample load.

Questions about EC 4/2 NUCLEODUR 100-5 C8 ec
What is this article?
EC 4/2 NUCLEODUR 100-5 C8 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.
