Description
EC 4/2 NUCLEODUR HILIC, 1,8 µm is an HPLC guard column for protecting analytical main columns in hydrophilic interaction liquid chromatography. The cartridge measures 4 mm in length with a 2 mm internal diameter and is intended for main columns with 2 mm ID. It is packed with NUCLEODUR HILIC material at 1,8 µm particle size, matching HILIC methods that rely on this phase chemistry for polar analyte retention. Each pack contains 3 pieces and comes from manufacturer Macherey-Nagel in the EC guard format used with compatible holders. Installation requires the Column Protection System guard column holder (REF 718966). Positioned upstream of the analytical column, the guard packing helps capture particulates and strongly retained matrix constituents before they reach the main bed. The EC 4/2 geometry aligns with narrow-bore HPLC systems operating 2 mm ID columns under HILIC conditions. These precolumns are classified among HPLC chromatography columns and act as consumable front-end protection elements, supporting method continuity on matching NUCLEODUR HILIC analytical columns rather than replacing the primary separation column.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR HILIC, 1.8 µm
What is this article?
EC 4/2 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.
