Description
EC 4/3 NUCLEOSHELL RP 18plus, 2,7 µm is an HPLC guard column for protecting analytical main columns during reversed-phase separations. The EC cartridge has a length of 4 mm and an internal diameter of 3 mm, filled with NUCLEOSHELL RP 18plus core-shell particles of 2,7 µm. It is supplied in packs of three and is intended for main columns with 3 mm, 4 mm or 4,6 mm internal diameter. Installation requires the Column Protection System guard-column holder (REF 718966). By capturing particulates and strongly retained sample constituents upstream of the analytical bed, the guard column helps maintain peak shape and prolongs main-column service life while preserving the selectivity of the NUCLEOSHELL RP 18plus chemistry. Available from manufacturer Macherey-Nagel, this guard format supports routine HPLC and UHPLC methods that rely on standard-bore reversed-phase columns and need a compact, replaceable protection element matched to the RP 18plus stationary phase.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 4/3 NUCLEOSHELL RP 18plus, 2.7 µm
What is this article?
EC 4/3 NUCLEOSHELL RP 18plus, 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.
