Description
EC 250/3 NUCLEODUR C18 Pyramid, 5 µm is an EC HPLC separation column for high-performance liquid chromatography applications in analytical laboratories. It offers a column length of 250 mm, an internal diameter of 3 mm, and a 5 µm NUCLEODUR C18 Pyramid packing designed for reverse-phase separations on standard HPLC platforms. The EC hardware style supports reliable installation in conventional systems and aligns with methods that specify this intermediate bore size together with a longer bed length. Packaged as a single column, it is suitable for method establishment, routine quality control, and analytical sequences needing a 250 mm × 3 mm, 5 µm C18 column. NUCLEODUR C18 Pyramid from manufacturer Macherey-Nagel provides a C18-bonded medium at the stated particle size for pharmaceutical, environmental, or general chemical sample work. Documented length and internal diameter simplify matching to existing protocols and instrument fittings. Each unit is intended for use on compatible HPLC instrumentation where these dimensional and particle-size characteristics are required for consistent chromatographic performance in daily laboratory practice.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

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