Description
EC 250/4.6 NUCLEOSIL 300-5 C18 is an EC HPLC separation column designed for analytical liquid chromatography. The column measures 250 mm in length with an internal diameter of 4,6 mm and is packed with the NUCLEOSIL 300-5 C18 stationary phase. C18 bonding delivers strong reversed-phase retention, supporting separation of non-polar and moderately polar analytes across pharmaceutical, chemical, and research workflows. The 4,6 mm ID matches common HPLC hardware, facilitating straightforward installation in standard analytical systems for routine assays, method transfer, and impurity profiling. Each unit is offered as one piece with a net weight of 0,28 kg, suitable for dedicated instrument channels or shared laboratory setups. The EC format from manufacturer Macherey-Nagel combines defined column geometry with the established NUCLEOSIL 300-5 C18 packing identity. This 250 mm × 4,6 mm configuration is a practical choice whenever a full-length analytical C18 column is specified for quantitative HPLC or preparative scouting at analytical scale. Integrate it into existing liquid chromatography methods that call for classic octadecyl selectivity and EC hardware dimensions.

Questions about EC 250/4.6 NUCLEOSIL 300-5 C18
What is this article?
EC 250/4.6 NUCLEOSIL 300-5 C18 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 × 2.1 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.
