Description
EC 4/3 NUCLEODUR PFP is an HPLC guard column with a particle size of 1,8 µm for protecting analytical HPLC main columns. The cartridge measures 4 mm in length with an internal diameter of 3 mm and is specified for main columns with 3 mm, 4 mm or 4,6 mm internal diameter. It is delivered as a pack of three pieces, enabling convenient replacement of the protective bed during regular system maintenance. Use requires the Column Protection System guard column holder (REF 718966), which holds the cartridge upstream of the analytical column in the HPLC flow path. In this arrangement the guard column helps intercept particulates and strongly retained components before they contact the primary packing. The NUCLEODUR PFP phase in EC 4/3 format is offered by manufacturer Macherey-Nagel for laboratories operating HPLC methods on 3 mm, 4 mm or 4,6 mm ID columns that need a dimensionally matched guard cartridge. Stocking these 4 mm × 3 mm guard columns supports uninterrupted sequences, straightforward column care, and stable day-to-day chromatographic performance whenever the protective cartridge must be exchanged without replacing the main NUCLEODUR PFP analytical column.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODUR PFP, 1.8 µM
What is this article?
EC 4/3 NUCLEODUR PFP, 1.8 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.
