Beschrijving
EC 250/4.6 NUCLEOSIL 100-5 NH2 is an EC HPLC separation column intended for analytical liquid chromatography. The column provides a length of 250 mm and an internal diameter of 4,6 mm together with the NUCLEOSIL 100-5 NH2 stationary phase named in the designation. This standard analytical format supports HPLC methods that require an EC-style column packed with NUCLEOSIL 100-5 NH2 media. Supplied as one piece, it is practical for laboratories running routine separations, method transfer, or dedicated amino-phase work on conventional HPLC systems. The 250 mm bed length and 4,6 mm internal diameter establish the geometric basis for flow rate and retention behaviour under typical HPLC conditions. EC construction matches widely used analytical instrument connections found in research and quality-control laboratories. The column comes from manufacturer Macherey-Nagel as part of the NUCLEOSIL range of silica-based HPLC phases. Users who specify EC 250/4.6 hardware with NUCLEOSIL 100-5 NH2 chemistry obtain a clearly defined length, diameter, and phase combination for integration into existing chromatographic workflows. Single-unit packaging simplifies procurement and stock control for chromatography laboratories maintaining NH2-phase columns.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/4.6 NUCLEOSIL 100-5 NH2
What is this article?
EC 250/4.6 NUCLEOSIL 100-5 NH2 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC-kolommen, inside HPLC-kolommen & accessoires, in Chromatografie.
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.
