Description
EC 4/3 UNIVERSAL RP is an HPLC guard column (pre-column) for protecting analytical HPLC columns operated under reversed-phase (RP) conditions. The cartridge has a length of 4 mm and an internal diameter of 3 mm and is intended for main columns with 3, 4 or 4,6 mm internal diameter. UNIVERSAL RP chemistry makes the unit suitable across typical reversed-phase method setups where a short upstream bed is used to shield the analytical column.
This article is part of HPLC columns, in HPLC columns & accessories.
The product is supplied as a pack of 3 pieces. Correct mounting requires the Column Protection System guard column holder (REF 718966), which is not included with the cartridges. In routine HPLC workflows the EC 4/3 format provides a compact, replaceable guard element matched to common analytical column diameters. These guard columns from manufacturer Macherey-Nagel support laboratories that run RP separations and need a dedicated EC-series pre-column compatible with the specified holder system. Dimensions, pack content and RP compatibility follow the stated product data for straightforward selection beside matching main columns.

Questions about EC 4/3 UNIVERSAL RP
What is this article?
EC 4/3 UNIVERSAL RP 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.
