Description
EC 75/4.6 NUCLEODUR C18 Pyramid, 3 µm is an EC HPLC separation column for high-performance liquid chromatography. It combines a NUCLEODUR C18 Pyramid stationary phase with a 3 µm particle size, a column length of 75 mm and an internal diameter of 4,6 mm, giving a compact analytical format for reversed-phase work. The single-piece pack is intended for laboratories that need reliable retention and peak shape in routine separations of polar and less polar analytes. Method development, quality control and research workflows can use this geometry where moderate length and a standard 4,6 mm bore are preferred. The column is offered by manufacturer Macherey-Nagel as part of the NUCLEODUR C18 Pyramid EC series and fits conventional HPLC systems without special hardware changes. Fine 3 µm particles support efficient mass transfer across typical analytical flow rates, while the defined 75 mm bed length keeps run times practical. Applications span pharmaceutical, environmental and general chemical analysis wherever a C18 Pyramid phase in EC hardware is specified.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 75/4.6 NUCLEODUR C18 Pyramid, 3 µm
What is this article?
EC 75/4.6 NUCLEODUR C18 Pyramid, 3 µm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC columns, inside HPLC columns & accessories, in Chromatography equipment.
An HPLC column is specified by the stationary phase, the particle size, the length and the internal diameter. A C18, 5 µm, 150 × 4.6 mm column is a different article from a C18, 3 µm, 100 × 2.1 mm column. The smaller bore belongs on a lower flow. A column has a direction and a pH range.
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.
