Description
EC 4/3 NUCLEODUR 100-5 NH2-RP is an HPLC guard column designed to protect analytical main columns during liquid chromatography. With a length of 4 mm and an internal diameter of 3 mm, this precolumn is specified for main columns with 3 mm, 4 mm or 4,6 mm internal diameter. It is packed with the NUCLEODUR 100-5 NH2-RP phase for amino reversed-phase applications where sample matrix load and column lifetime are practical concerns. The product is supplied as a pack of 3 pieces from manufacturer Macherey-Nagel in the EC guard cartridge format. Use requires the Column Protection System guard column holder (REF 718966). Mounted ahead of the analytical column, the guard bed helps retain particulates and strongly adsorbed components that would otherwise foul the main packing. The EC 4/3 dimensions suit common analytical HPLC column diameters in the 3–4,6 mm ID range when NH2-RP selectivity is employed. These cartridges function as replaceable protection elements within HPLC chromatography column setups, supporting stable routine separations on matching NUCLEODUR main columns without serving as the primary separation device themselves.

Questions about EC 4/3 NUCLEODUR 100-5 NH2-RP
What is this article?
EC 4/3 NUCLEODUR 100-5 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.
