Description
EC 4/2 NUCLEOSHELL HILIC, 2,7 µm is an HPLC guard column (precolumn) for hydrophilic interaction liquid chromatography. Each cartridge is 4 mm long with a 2 mm internal diameter and is packed with 2,7 µm NUCLEOSHELL HILIC material. The pack contains three pieces and is intended for main columns with 2 mm internal diameter. Use requires a Column Protection System guard-column holder (REF 718966). Offered by manufacturer Macherey-Nagel, these short EC guard elements help protect the analytical NUCLEOSHELL HILIC column from particulate and strongly retained matrix components in HILIC methods. Matching the 2,7 µm HILIC phase and 2 mm ID to the main column supports consistent selectivity at the system inlet. The compact 4 mm length keeps extra-column volume low while still providing a replaceable protective bed. Laboratories running narrow-bore HILIC separations can integrate this guard format into existing EC hardware setups once the specified holder is in place, simplifying maintenance without changing the primary separation chemistry.
This article is part of HPLC columns, in HPLC columns & accessories.

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