Description
EC 4/3 NUCLEOSHELL HILIC is an HPLC guard column with 2,7 µm particle size, designed to protect analytical columns in hydrophilic interaction liquid chromatography workflows. The cartridge measures 4 mm in length with a 3 mm internal diameter and is intended for use with main columns of 3 mm, 4 mm or 4,6 mm ID. Supplied as a pack of three pieces, these guard columns require the Column Protection System guard-column holder (REF 718966) for installation. The NUCLEOSHELL HILIC chemistry supports polar analyte retention and is suited to method development and routine HPLC separations where column lifetime and peak integrity matter. This format from manufacturer Macherey-Nagel fits standard EC-style HPLC systems and helps reduce particulate and matrix load reaching the analytical bed. Compact dimensions keep extra-column volume low while maintaining compatibility with common analytical internal diameters used in pharmaceutical, environmental and life-science laboratories.
This article is part of HPLC columns, in HPLC columns & accessories.

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