Description
EC 125/3 NUCLEODUR C18 Pyramid, 3 µm is an EC HPLC separation column for high-performance liquid chromatography. It features a NUCLEODUR C18 Pyramid stationary phase with 3 µm particles, a column length of 125 mm and an internal diameter of 3 mm, balancing resolution with practical flow and solvent use. The unit is packed as a single column for laboratories performing reversed-phase separations of polar and less polar compounds. Longer bed length supports improved plate count versus shorter EC formats, while the 3 mm bore remains compatible with many analytical HPLC setups. Offered by manufacturer Macherey-Nagel within the NUCLEODUR C18 Pyramid EC family, the column is intended for method development, routine QC and research applications. Fine 3 µm packing promotes efficient mass transfer and well-defined peaks under typical gradient or isocratic conditions. Pharmaceutical, environmental and general chemical laboratories can deploy this geometry whenever a 125 mm × 3 mm C18 Pyramid EC column is required for chromatographic separation tasks.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 125/3 NUCLEODUR C18 Pyramid, 3 µm
What is this article?
EC 125/3 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.
