Description
EC 250/4 NUCLEODUR C18 Isis, 3 µm is an EC HPLC separation column for high-performance liquid chromatography applications. It features a length of 250 mm and an internal diameter of 4 mm, packed with NUCLEODUR C18 Isis stationary phase at a particle size of 3 µm. The EC 250/4 format is aimed at analytical HPLC methods that use a conventional 4 mm bore with a 250 mm bed length and C18 Isis chemistry.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.
The product is delivered as a single column pack for use on EC-compatible HPLC systems. Specified length, internal diameter and 3 µm particle size allow laboratories to match instrument configuration and method parameters to this geometry. NUCLEODUR C18 Isis supports reversed-phase chromatographic separations in research, method development and quality-control laboratories that depend on consistent column dimensions.
Offered by manufacturer Macherey-Nagel as part of the NUCLEODUR column family, this unit carries the EC 250/4 designation for 250 mm length and 4 mm internal diameter. The 3 µm packing characterises the phase particle size. One piece is included per package, providing a ready HPLC chromatography column for professional analytical workflows that require NUCLEODUR C18 Isis in the EC 250/4 format.

Questions about EC 250/4 NUCLEODUR C18 Isis, 3 µm
What is this article?
EC 250/4 NUCLEODUR C18 Isis, 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.
