Description
EC 4/3 NUCLEODUR SPHINX RP, 1,8 µm is an HPLC guard column designed to shield analytical main columns during reversed-phase chromatography. With a length of 4 mm and an internal diameter of 3 mm, it is intended for main columns of 3, 4 or 4,6 mm ID, trapping particulates and strongly retained contaminants ahead of the analytical bed. The NUCLEODUR SPHINX RP stationary phase supports robust reversed-phase separations in everyday HPLC, QC and method-development settings. Packs of three guard columns from manufacturer Macherey-Nagel require the Column Protection System guard column holder (REF 718966) for installation. The EC 4/3 format offers practical precolumn protection for common analytical column diameters while keeping system dead volume under control. Using the same phase family on guard and main column helps preserve retention behaviour and peak integrity throughout longer sample sequences. These cartridges fit laboratories that already operate 3, 4 or 4,6 mm ID HPLC columns with the matching protection-system hardware.
This article is part of HPLC columns, in HPLC columns & accessories.

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