Description
EC 4/2 UNIVERSAL RP is an HPLC guard column designed for use with analytical HPLC columns under reversed-phase (RP) conditions. It has a length of 4 mm and an internal diameter of 2 mm, and is specified for main columns with 2 mm internal diameter. The UNIVERSAL RP designation indicates suitability for reversed-phase chromatography setups that benefit from a short protective pre-column ahead of the analytical bed.
This article is part of HPLC guard columns, in HPLC columns & accessories.
Each package contains 9 pieces. Installation requires the Column Protection System guard column holder (REF 718966), which must be available separately. The narrow-bore EC 4/2 geometry aligns with 2 mm ID main columns used in many modern HPLC applications where reduced internal diameter is preferred. Offered by manufacturer Macherey-Nagel, this EC-series guard cartridge gives laboratories a matched consumable for RP methods on 2 mm columns when used with the designated holder. Length, internal diameter, pack size and RP compatibility are taken directly from the product specification for clear pairing with compatible analytical columns.

Questions about EC 4/2 UNIVERSAL RP, 9 pcs.
What is this article?
EC 4/2 UNIVERSAL RP, 9 pcs. 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.
