Description
EC 250/4 NUCLEODUR C18 Isis, 5 µm is an EC HPLC separation column intended for liquid chromatography in the analytical laboratory. The column offers a length of 250 mm, an internal diameter of 4 mm and a NUCLEODUR C18 Isis stationary phase with 5 µm particles. This EC 250/4 configuration helps laboratories match column geometry and phase chemistry to existing HPLC methods and system fittings. Supplied as one column per pack, it is ready for use in instruments that accept the EC format. Length, internal diameter, particle size and the C18 Isis designation are stated explicitly to simplify selection among related NUCLEODUR EC columns. The product comes from manufacturer Macherey-Nagel and belongs to the EC HPLC column range used for professional chromatographic separations. Each pack contains 1 pc, supporting single-instrument installation or scheduled replacement. The defined 250 mm length, 4 mm internal diameter and 5 µm NUCLEODUR C18 Isis packing provide a clear specification set for routine HPLC work where this geometry and phase are required.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/4 NUCLEODUR C18 Isis, 5 µm
What is this article?
EC 250/4 NUCLEODUR C18 Isis, 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.
