Description
EC 4/2 NUCLEOSHELL RP 18plus, 2,7 µm is an HPLC guard column designed to protect analytical main columns in reversed-phase liquid chromatography. The short EC cartridge measures 4 mm in length with a 2 mm internal diameter and is packed with NUCLEOSHELL RP 18plus core-shell material at 2,7 µm particle size. Supplied as a pack of three pieces, these guard columns are intended for use with main columns of 2 mm internal diameter and require the Column Protection System guard-column holder (REF 718966) for installation. The NUCLEOSHELL RP 18plus phase supports efficient sample clean-up and extends the lifetime of the analytical column by retaining particulates and strongly retained matrix components before they reach the main bed. This configuration from manufacturer Macherey-Nagel is suited to modern HPLC and UHPLC workflows that employ narrow-bore columns, offering a practical front-end protection step without altering the selectivity of the primary separation. Ideal for routine analytical laboratories seeking reliable column safeguarding in RP 18plus applications.

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