Description
EC 4/3 NUCLEODUR Pi2, 5 µm is an HPLC guard column designed to protect analytical main columns in liquid chromatography workflows. The cartridge measures 4 mm in length with an internal diameter of 3 mm and is packed with NUCLEODUR Pi2 material at a 5 µm particle size. Supplied in a pack of three pieces, it is intended for use with main columns of 3, 4 or 4,6 mm internal diameter. Installation requires the Column Protection System guard column holder (REF 718966). This EC-format precolumn from manufacturer Macherey-Nagel helps intercept particulate matter and strongly retained sample components before they reach the analytical bed, supporting stable retention behaviour and longer column lifetime in routine HPLC separations. The compact EC 4/3 geometry matches common narrow- and standard-bore column formats, making the unit suitable for method development, quality control and preparative sample clean-up steps where a matching Pi2 phase is already in use. Each pack provides three ready-to-mount cartridges for convenient replacement during continuous laboratory operation.
This article belongs on HPLC guard columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODUR Pi2, 5 µm
What is this article?
EC 4/3 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 Chromatographie.
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.
