Description
EC 250/4.6 NUCLEOSIL 500-7 C18 is an EC HPLC separation column for high-performance liquid chromatography. Column length is 250 mm and internal diameter is 4,6 mm, in line with the EC 250/4.6 format. The column is packed with the NUCLEOSIL 500-7 C18 stationary phase indicated by the product designation and is intended for analytical HPLC work that specifies this phase and geometry. It is supplied as one piece for installation in standard HPLC systems that accept EC-format columns. Laboratories can use this column wherever methods call for a 250 mm × 4,6 mm NUCLEOSIL 500-7 C18 configuration. The product comes from manufacturer Macherey-Nagel as part of the NUCLEOSIL HPLC column range. Pack size is a single complete column, supporting straightforward stocking for routine separations and method work. With a net weight of 0,23 kg, the packaged unit is practical to handle and store. The EC 250/4.6 NUCLEOSIL 500-7 C18 column provides the defined length, diameter, and C18 phase identity required for chromatographic applications built around this NUCLEOSIL designation.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 250/4.6 NUCLEOSIL 500-7 C18
What is this article?
EC 250/4.6 NUCLEOSIL 500-7 C18 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.
