Description
EC 125/3 NUCLEODUR C18 Gravity-SB, 5 µm is an EC HPLC separation column for high-performance liquid chromatography applications. It features a column length of 125 mm, an internal diameter of 3 mm, and NUCLEODUR C18 Gravity-SB stationary phase with a particle size of 5 µm. The 125 mm × 3 mm EC format with 5 µm particles addresses analytical methods that specify this intermediate diameter and bed length for reversed-phase work. The product is packed as a single column, ready for installation on compatible HPLC systems or for replacement of an equivalent EC column. This separation column from manufacturer Macherey-Nagel is identified by the NUCLEODUR C18 Gravity-SB phase designation within the EC HPLC series. Laboratories choose the 125 mm length, 3 mm internal diameter, and 5 µm particle size when those parameters are fixed in the analytical method. Packaged net weight is 0,19 kg. The column fits standard EC HPLC instrument connections and is intended for pharmaceutical, chemical, and general analytical laboratories that require a C18 EC column in the stated dimensions without deviation from the specified geometry and phase type.
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, 5 µm
What is this article?
EC 125/3 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.
