Description
EC 4/3 NUCLEODUR HILIC is an HPLC guard column with a 1,8 µm particle size for hydrophilic interaction liquid chromatography. The cartridge is 4 mm long with a 3 mm internal diameter and is intended for main columns of 3, 4 or 4,6 mm internal diameter. Packed as three pieces per pack, these precolumns help protect the analytical bed by retaining particulates and strongly retained matrix components before they reach the primary separation column. The NUCLEODUR HILIC phase from manufacturer Macherey-Nagel is suited to HILIC work with polar analytes under typical HPLC instrument conditions. Use requires the Column Protection System guard column holder (REF 718966), which seats the EC-format cartridge in a standard protection assembly. This geometry supports routine method transfer onto analytical columns of matching diameter without redesigning the separation. Laboratories in pharmaceutical, biochemical and general analytical settings can deploy the EC 4/3 format wherever HILIC selectivity is needed and column lifetime must be preserved. Compact dimensions and a defined particle size make system configuration straightforward for day-to-day HPLC workflows.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODUR HILIC, 1.8 µm
What is this article?
EC 4/3 NUCLEODUR HILIC, 1.8 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.
