Description
EC 250/2 NUCLEODUR C18 Pyramid, 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 2 mm, and is packed with NUCLEODUR C18 Pyramid material at a particle size of 3 µm. This EC-format geometry is identified clearly by the EC 250/2 designation, linking length, internal diameter and phase in one product name for straightforward selection in HPLC inventories. Supplied as a single piece from manufacturer Macherey-Nagel, the column fits laboratory workflows that require a C18 Pyramid stationary phase in a narrow-bore analytical format. The 250 mm length provides a standard analytical bed length, while the 2 mm internal diameter defines the EC 250/2 cross-section used on compatible HPLC systems. Particle size of 3 µm is stated in the product designation so method documentation and ordering remain unambiguous. Pack size is one column per package, suitable for dedicated methods or single-column replacement. The product belongs to the HPLC chromatography column category and is offered for separation tasks that specify this length, diameter and NUCLEODUR C18 Pyramid, 3 µm combination.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

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