Description
EC 125/3 NUCLEODUR C18 Gravity-SB is an EC HPLC separation column for high-performance liquid chromatography applications. It features a column length of 125 mm and an internal diameter of 3 mm, filled with 3 µm NUCLEODUR C18 Gravity-SB stationary-phase particles. This reversed-phase C18 chemistry supports analytical separations of organic compounds in pharmaceutical, environmental, food, and research laboratories. The product is packed as one piece and is intended for use on HPLC systems compatible with the EC column format. NUCLEODUR C18 Gravity-SB from manufacturer Macherey-Nagel provides a defined C18 surface suitable for method development, quality control, and routine quantitative work under reversed-phase conditions. The 3 µm particle size and 125 mm × 3 mm geometry enable efficient chromatographic resolution at typical analytical flow rates. This EC HPLC column can be applied in isocratic or gradient methods wherever a Gravity-SB C18 phase is required, and it supports straightforward column exchange and method transfer between instruments.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 125/3 NUCLEODUR C18 Gravity-SB, 3 µm
What is this article?
EC 125/3 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.
