Description
EC 250/3 NUCLEODUR C18 Gravity-SB, 5 µm is an EC HPLC separation column designed for analytical high-performance liquid chromatography. It combines a length of 250 mm with an inner diameter of 3 mm and a particle size of 5 µm on the NUCLEODUR C18 Gravity-SB stationary phase. This configuration is well suited to reverse-phase separations that demand dependable C18 selectivity across diverse analyte classes. The column is packed as a single piece and supports method development, routine analysis and quality-control applications in pharmaceutical, chemical and research environments. Its EC format matches common HPLC instrument interfaces for simple installation. The NUCLEODUR C18 Gravity-SB chemistry from manufacturer Macherey-Nagel delivers stable performance under a wide range of mobile-phase conditions. With the 250 × 3 mm geometry and 5 µm particles, users obtain a useful combination of chromatographic efficiency and manageable system pressure, enabling reproducible results within established laboratory workflows.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/3 NUCLEODUR C18 Gravity-SB, 5 µm
What is this article?
EC 250/3 NUCLEODUR C18 Gravity-SB, 5 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.
