Description
EC 250/4.6 NUCLEODUR C8 Gravity, 3 µm is an EC HPLC separation column for high-performance liquid chromatography. It combines a bed length of 250 mm with an internal diameter of 4,6 mm and is packed with 3 µm NUCLEODUR C8 Gravity particles for reversed-phase work. The octyl-bonded phase supports method development and routine analytical separations where moderate hydrophobicity and stable retention are required. Supplied as one column per pack, the EC format fits conventional HPLC hardware used in pharmaceutical, environmental and research laboratories. This Macherey-Nagel column offers a defined geometry that helps laboratories maintain consistent peak shape and resolution under standard analytical flow rates. The 250 mm path length extends analyte–stationary-phase interaction for improved separation of closely eluting compounds, while the 4,6 mm bore remains compatible with typical UV, MS and other detectors. Use it wherever a C8 Gravity phase in EC dimensions is specified for quality control, impurity profiling or general organic analysis.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/4.6 NUCLEODUR C8 Gravity, 3 µm
What is this article?
EC 250/4.6 NUCLEODUR C8 Gravity, 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 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.
