Description
EC 4/3 NUCLEOSHELL BB RP 18, 2,7 µm is an HPLC guard column cartridge designed to shield analytical reversed-phase columns from particulates and strongly retained contaminants. The unit offers a 4 mm length and 3 mm internal diameter, filled with NUCLEOSHELL Bluebird RP 18 material at 2,7 µm particle size. Supplied as a pack of three, it is specified for main columns with 3 mm, 4 mm or 4,6 mm internal diameter. Guard columns from manufacturer Macherey-Nagel must be used with the Column Protection System guard column holder (REF 718966). By intercepting matrix load before it reaches the analytical bed, the cartridge supports consistent chromatography, reduced pressure rise and longer column service life in daily HPLC operation. The EC geometry integrates into common HPLC setups across pharmaceutical QC, environmental monitoring, food analysis and academic research. Bluebird RP 18 chemistry aligns with matching NUCLEOSHELL analytical columns for reversed-phase separations, providing a convenient protective option for medium-bore and conventional analytical column formats.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

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