Description
EC 4/3 NUCLEODUR HILIC is an HPLC guard column with a 3 µm particle size intended for hydrophilic interaction liquid chromatography. The cartridge is 4 mm long with a 3 mm internal diameter and fits main columns of 3, 4 or 4,6 mm internal diameter. Delivered as three pieces per pack, these precolumns help protect the analytical separation bed by capturing particulates and strongly retained matrix components before they reach the primary column. The NUCLEODUR HILIC phase from manufacturer Macherey-Nagel is appropriate for HILIC analysis of polar analytes under standard HPLC instrument conditions. Mounting requires the Column Protection System guard column holder (REF 718966), which accepts the EC-format cartridge in a dedicated protection assembly. The EC 4/3 geometry aligns with common analytical column diameters, supporting straightforward configuration without method redesign. Pharmaceutical, biochemical and general analytical laboratories can apply this guard column wherever HILIC selectivity is required and column lifetime is a priority. Compact dimensions and a clearly specified particle size simplify integration into routine HPLC workflows.
This article is part of HPLC columns, in HPLC columns & accessories.

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