Description
EC 4/3 NUCLEOSHELL PFP is an HPLC guard column packed with 2,7 µm core-shell particles and a pentafluorophenyl (PFP) stationary phase for protecting analytical HPLC columns. The cartridge length is 4 mm with a 3 mm internal diameter, and it is designed for main columns with 3, 4 or 4,6 mm ID. Placed upstream of the analytical column, the guard bed traps particulates and strongly retained sample components, helping to preserve chromatographic performance and extend column service life. Supplied as a pack of three pieces from manufacturer Macherey-Nagel, the cartridges must be mounted in the Column Protection System guard column holder (REF 718966). NUCLEOSHELL PFP chemistry delivers selectivity distinct from conventional alkyl phases via π–π, hydrophobic and dipole interactions, supporting methods for aromatic and halogenated compounds. These EC-format precolumns are a practical consumable for laboratories running standard-bore HPLC in quality control, method development and research environments.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEOSHELL PFP, 2.7 µm
What is this article?
EC 4/3 NUCLEOSHELL PFP, 2.7 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.
