Description
EC 4/2 NUCLEODUR 100-3 NH2-RP is an HPLC guard column intended to protect analytical main columns during liquid chromatography. The cartridge measures 4 mm in length with a 2 mm internal diameter and is specified for use with main columns of 2 mm ID, helping retain particulates and strongly adsorbed sample components before they reach the analytical bed. Its NUCLEODUR 100-3 NH2-RP phase designation aligns the guard chemistry with corresponding amino reverse-phase separations on matching analytical columns. Each pack contains three guard columns and requires the Column Protection System guard column holder (REF 718966) for correct mounting in the flow path. These EC-format precolumns from manufacturer Macherey-Nagel support routine HPLC method protection where a short, narrow-bore guard is preferred. Matching the 2 mm ID geometry of the main column preserves flow characteristics and chromatographic integrity across analytical runs. The compact EC 4/2 format integrates readily into HPLC systems configured for 2 mm columns and is supplied ready for installation once the dedicated holder is in place.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR 100-3 NH2-RP
What is this article?
EC 4/2 NUCLEODUR 100-3 NH2-RP 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.
