Description
EC 4/2 NUCLEODUR Pi2, 3 µm is an HPLC guard column configured for narrow-bore analytical systems. The cartridge has a length of 4 mm and an internal diameter of 2 mm, and is filled with NUCLEODUR Pi2 stationary phase at a 3 µm particle size. It is supplied as a pack of three pieces and is intended exclusively for main columns with 2 mm internal diameter. A Column Protection System guard column holder (REF 718966) is required for mounting. Offered by manufacturer Macherey-Nagel, this EC-format precolumn shields the analytical column from particulates and strongly adsorbing matrix components, helping maintain peak shape and system pressure stability during extended HPLC runs. The 2 mm internal diameter matches microbore and narrow-bore main columns, supporting low-volume separations in research, method transfer and routine analysis where a Pi2 selectivity is already established. Three replaceable cartridges per pack allow straightforward exchange whenever back-pressure rise or peak distortion indicates that the guard bed should be renewed, without interrupting the main column installation.

Questions about EC 4/2 NUCLEODUR Pi2, 3 µm
What is this article?
EC 4/2 NUCLEODUR Pi2, 3 µm 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.
