Description
EC 250/2 NUCLEOSHELL RP 18, 5 µm is an EC HPLC separation column intended for reversed-phase liquid chromatography. The column is 250 mm long with a 2 mm internal diameter and contains NUCLEOSHELL RP 18 stationary phase at a 5 µm particle size, a geometry well suited to higher-efficiency analytical work and reduced solvent consumption. Delivered as one piece, it supports method transfer, impurity profiling, and routine assays in research and quality-control environments. The longer bed length enhances resolution for complex mixtures, while the narrow bore format lowers flow rates relative to conventional 4,6 mm columns. Available from manufacturer Macherey-Nagel, the EC configuration mounts on standard HPLC instruments with appropriate microbore or narrow-bore fittings and detectors. Laboratories can apply isocratic or gradient elution with common reversed-phase solvents to separate a broad range of organic analytes. Defined length, diameter, and particle size make this column a clear option when protocols call for NUCLEOSHELL RP 18 performance in a 250 mm × 2 mm format.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/2 NUCLEOSHELL RP 18, 5 µm
What is this article?
EC 250/2 NUCLEOSHELL RP 18, 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.
