Description
EC 4/2 NUCLEODUR 100-5 NH2-RP is an HPLC guard column (precolumn) for protecting analytical main columns in liquid chromatography. It has a length of 4 mm and an internal diameter of 2 mm, and is intended for main columns with 2 mm ID. The cartridge is packed with the NUCLEODUR 100-5 NH2-RP stationary phase, supporting amino reversed-phase HPLC workflows where front-end protection of the analytical bed is required. Each unit is supplied as a pack of 3 pieces from manufacturer Macherey-Nagel and fits the EC guard format used with compatible column hardware. Installation requires the Column Protection System guard column holder (REF 718966). Placed upstream of the separation column, the guard cartridge helps intercept particulates and strongly retained matrix components before they reach the main packing. The compact EC 4/2 geometry matches narrow-bore HPLC systems that run 2 mm ID columns and use NUCLEODUR-based NH2-RP chemistry. These replaceable precolumns belong to the HPLC chromatography columns category and serve as consumable protection elements rather than primary separation devices, supporting routine method continuity on matching analytical columns.

Questions about EC 4/2 NUCLEODUR 100-5 NH2-RP
What is this article?
EC 4/2 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.
