Description
EC 4/2 NUCLEODUR Pi2, 5 µm is an HPLC guard column cartridge with a length of 4 mm and an internal diameter of 2 mm, packed with 5 µm NUCLEODUR Pi2 stationary phase. The short precolumn protects analytical main columns of 2 mm ID by retaining particulates and strongly adsorbed contaminants before they reach the primary bed, helping to preserve efficiency and extend column lifetime. Installation requires a Column Protection System guard-column holder (REF 718966). This EC 4/2 format from manufacturer Macherey-Nagel is intended for HPLC methods that already use 2 mm internal diameter main columns and matching particle sizes. The 5 µm packing aligns with common analytical dimensions so the guard can be integrated without disrupting established separations. It is supplied in a pack of 3 pieces. Typical use includes pharmaceutical, environmental and research chromatography where costly analytical columns benefit from upstream protection. The compact cartridge format supports straightforward exchange when the guard becomes loaded, maintaining system performance in routine and method-development workflows.

Questions about EC 4/2 NUCLEODUR Pi2, 5 µm
What is this article?
EC 4/2 NUCLEODUR Pi2, 5 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.
