Description
EC 250/4.6 NUCLEODUR C18 Gravity-SB, 3 µm is an EC HPLC separation column for high-performance liquid chromatography. The column has a length of 250 mm and an internal diameter of 4,6 mm, and is packed with 3 µm NUCLEODUR C18 Gravity-SB particles for reversed-phase separations. This geometry suits standard analytical HPLC systems where defined retention, peak shape and method transfer are required. It is supplied as one piece per pack for straightforward instrument setup and stock control. The NUCLEODUR C18 Gravity-SB stationary phase from manufacturer Macherey-Nagel is intended for robust chromatographic work under typical mobile-phase conditions used in routine and development laboratories. Applications include pharmaceutical, chemical and environmental analysis where C18 selectivity on a silica-based support is needed. The EC format integrates into conventional HPLC hardware, supporting method development, quality control and day-to-day sample analysis. Clear dimensional and particle-size specification help match the column to existing methods and system dead-volume requirements without ambiguity.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/4.6 NUCLEODUR C18 Gravity-SB, 3µm
What is this article?
EC 250/4.6 NUCLEODUR C18 Gravity-SB, 3µm 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.
