Description
EC 250/4 NUCLEODUR 100-5 NH2 is an EC HPLC separation column intended for liquid chromatography applications. The column provides a length of 250 mm and an internal diameter of 4 mm, combined with the NUCLEODUR 100-5 NH2 stationary phase indicated by the product name. A longer 250 mm bed with a 4 mm bore supports analytical HPLC work where extended path length is preferred for resolution while retaining a compact internal diameter. Each unit is packed as one piece, suitable for direct use on HPLC instruments that accept 4 mm ID columns. Specifying length, internal diameter and phase designation in a single product identity simplifies selection against method requirements and system hardware. This EC series column from manufacturer Macherey-Nagel is aimed at professional laboratories performing HPLC separations that rely on the NUCLEODUR 100-5 NH2 chemistry. It fits research, method development and routine analytical environments in which defined column dimensions and a clear sorbent label are required for consistent chromatographic practice. The format is appropriate when a 250 mm column length and 4 mm internal diameter are specified for the analytical setup.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/4 NUCLEODUR 100-5 NH2
What is this article?
EC 250/4 NUCLEODUR 100-5 NH2 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.
