Description
EC 250/4 NUCLEODUR 100-5 NH2-RP is an EC HPLC separation column intended for analytical chromatography. The column measures 250 mm in length with an internal diameter of 4 mm, a common geometry for everyday HPLC methods. Its NUCLEODUR 100-5 NH2-RP designation denotes an amino reversed-phase stationary phase chosen for separations that benefit from NH2-RP selectivity toward polar and moderately polar compounds. The unit is packed as one piece for straightforward laboratory use and system installation. Offered by manufacturer Macherey-Nagel within the NUCLEODUR EC range, it supports routine analysis and method development on standard HPLC instruments. The 250 mm length provides a practical bed for efficient resolution, while the 4 mm internal diameter balances sample capacity and solvent consumption. Analysts specify this EC 250/4 format when an intermediate-bore NH2-RP column is required. Consistent naming with length and internal diameter aids selection among related NUCLEODUR HPLC columns in the same series.
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-RP
What is this article?
EC 250/4 NUCLEODUR 100-5 NH2-RP 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.
