Description
EC 250/4 NUCLEOSIL Anion II is an EC HPLC separation column for analytical liquid chromatography applications focused on anion-exchange style separations under the NUCLEOSIL Anion II designation. The column length is 250 mm and the internal diameter is 4 mm, giving the EC 250/4 hardware format used on standard HPLC systems. It is offered as a single piece for laboratories that need a defined analytical column geometry with the NUCLEOSIL Anion II phase identity stated in the product name. This configuration supports method work and routine sample analysis where anion-oriented HPLC media and a 250 mm bed are specified. Manufactured by Macherey-Nagel, the column fits research, development, and quality-control environments that already apply NUCLEOSIL phases. Net weight is 0,28 kg for the packed unit. As an HPLC chromatography column, EC 250/4 NUCLEOSIL Anion II provides a compact, clearly dimensioned separation tool for instruments set up for 4 mm internal diameter EC columns at 250 mm length, aligned with the Anion II product specification.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/4 NUCLEOSIL Anion II
What is this article?
EC 250/4 NUCLEOSIL Anion II 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.
