Description
EC 250/2 NUCLEODUR C18 Gravity-SB, 3 µm is an EC HPLC separation column for reversed-phase high-performance liquid chromatography. It combines a column length of 250 mm with an internal diameter of 2 mm and a NUCLEODUR C18 Gravity-SB stationary phase at 3 µm particle size, giving a compact analytical format suited to efficient separations and moderate solvent use. The C18 bonded phase supports typical reverse-phase method work on a broad range of organic and pharmaceutical analytes under standard HPLC conditions. This single-column pack from manufacturer Macherey-Nagel is intended for direct installation on compatible EC-format HPLC systems in research, method development and routine quality-control laboratories. The 250 mm bed length provides useful retention and resolution, while the 2 mm internal diameter favours lower flow rates compared with wider analytical columns. Laboratories seeking a defined NUCLEODUR C18 Gravity-SB geometry for established or new reversed-phase methods can deploy this column as a ready-to-use separation element without further packing. Pack size is one piece, matching common single-column replacement and method-setup needs in analytical chromatography workflows.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/2 NUCLEODUR C18 Gravity-SB, 3 µm
What is this article?
EC 250/2 NUCLEODUR C18 Gravity-SB, 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.
