Description
EC 125/2 NUCLEODUR C18 Gravity-SB, 5 µm is an EC HPLC separation column intended for analytical high-performance liquid chromatography. The column has a length of 125 mm and an internal diameter of 2 mm, and is packed with NUCLEODUR C18 Gravity-SB material at a particle size of 5 µm. This narrow-bore EC geometry suits HPLC setups that call for a 2 mm internal diameter together with a 125 mm bed length and 5 µm particles. Supplied as one piece per pack, the column can be installed as a dedicated analytical column or used as a direct format replacement. From manufacturer Macherey-Nagel, the product belongs to the NUCLEODUR C18 Gravity-SB EC line, specifying a C18 bonded stationary phase in EC hardware. Analytical laboratories employ this configuration when methods are defined for 125 mm × 2 mm, 5 µm C18 columns. Net weight of the packaged unit is 0,21 kg. The column is designed for use with standard EC HPLC connections on common liquid chromatography instruments and supports separation tasks in pharmaceutical, chemical, and related laboratory environments where the stated dimensions and phase type are required.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 125/2 NUCLEODUR C18 Gravity-SB, 5 µm
What is this article?
EC 125/2 NUCLEODUR C18 Gravity-SB, 5 µm 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.
