Description
EC 125/2 NUCLEODUR C18 Gravity-SB is an EC HPLC separation column designed for high-performance liquid chromatography. The column has a length of 125 mm and an internal diameter of 2 mm, and is packed with 3 µm particles of the NUCLEODUR C18 Gravity-SB stationary phase. This reversed-phase C18 material is suited to analytical work on organic analytes in pharmaceutical, environmental, and research settings where narrower-bore formats are preferred. Supplied as a single column per pack, it fits HPLC instruments that accept the EC column hardware. The NUCLEODUR C18 Gravity-SB chemistry from manufacturer Macherey-Nagel offers a defined C18 surface for method development, quality control, and routine quantitative separations under reversed-phase conditions. The 3 µm particle size combined with the 125 mm bed length supports efficient resolution, while the 2 mm internal diameter matches low-flow analytical applications. Laboratories can integrate this EC HPLC column into existing setups for isocratic or gradient methods and for convenient column replacement or method transfer.
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, 3 µm
What is this article?
EC 125/2 NUCLEODUR C18 Gravity-SB, 3 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.
