Description
EC 4/2 NUCLEOSHELL RP 18, 2,7 µm is an HPLC guard column for protecting analytical main columns in reversed-phase liquid chromatography. It has a length of 4 mm and an internal diameter of 2 mm, so it is intended for main columns with 2 mm ID. The NUCLEOSHELL RP 18 packing uses 2,7 µm particles in the compact EC guard format, helping retain particulates and strongly retained matrix components before they reach the analytical bed and thereby supporting stable separations with lower extra-column volume on narrow-bore systems. Each pack contains three guard cartridges and requires the Column Protection System guard column holder (REF 718966) for correct mounting. Offered by manufacturer Macherey-Nagel, this EC 4/2 precolumn fits routine HPLC workflows in which 2 mm ID main columns are used for method development, quality control, or research separations. The short bed keeps the protective segment close to the column inlet while remaining fully compatible with the dedicated holder, making cartridge exchange straightforward during ongoing chromatographic work.

Questions about EC 4/2 NUCLEOSHELL RP 18, 2.7 µm
What is this article?
EC 4/2 NUCLEOSHELL 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.
