Description
EC 250/4.6 NUCLEOSIL 100-5 SB is an EC HPLC separation column for analytical liquid chromatography applications. It features a column length of 250 mm and an internal diameter of 4,6 mm, combined with the NUCLEOSIL 100-5 SB stationary phase to give a well-defined geometry and chemistry for laboratory use. The EC format is designed for reliable installation in conventional HPLC systems employed in research, quality control, and method development. This column is available as a single unit from manufacturer Macherey-Nagel and is intended for professional environments that need reproducible EC hardware with clearly stated dimensions. NUCLEOSIL 100-5 SB supports separations that benefit from strong-base ion-exchange selectivity on the established NUCLEOSIL silica base, offering an alternative to purely reversed-phase approaches. Net weight is 0,27 kg, supporting convenient handling and storage in the laboratory. As part of the NUCLEOSIL HPLC column range, it provides a practical 250 mm × 4,6 mm option whenever methods call for this specific length, diameter, and SB phase combination in routine or developmental chromatographic work.
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 SB
What is this article?
EC 250/4.6 NUCLEOSIL 100-5 SB 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.
