Description
EC 4/2 NUCLEODUR PFP is an HPLC guard column with a particle size of 1,8 µm, supplied for protection of analytical HPLC main columns. The cartridge length is 4 mm and the internal diameter is 2 mm, matching main columns that have a 2 mm internal diameter. Each pack contains three pieces, so spare cartridges are available for scheduled exchange during routine HPLC maintenance. Installation requires the Column Protection System guard column holder (REF 718966), which positions the guard bed in the flow path ahead of the analytical column. Used in this configuration, the EC 4/2 cartridge helps retain particulates and strongly retained sample constituents before they reach the primary separation column. The NUCLEODUR PFP phase in this EC guard format comes from manufacturer Macherey-Nagel and is intended for laboratories that run HPLC methods on 2 mm ID columns and need a matched protective cartridge. Keeping a ready stock of these 4 mm × 2 mm guard columns supports continuous operation, simpler column care, and consistent chromatographic workflows whenever the protective bed must be replaced without changing the main NUCLEODUR PFP analytical column.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR PFP, 1.8 µM
What is this article?
EC 4/2 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.
