Description
EC 50/4 NUCLEODUR C18 Pyramid, 1,8 µm is an EC HPLC separation column for high-performance liquid chromatography. The column has a length of 50 mm and an internal diameter of 4 mm, and is packed with NUCLEODUR C18 Pyramid stationary phase at a particle size of 1,8 µm. This C18-bonded phase is intended for reversed-phase separations in analytical workflows. Supplied as one piece from manufacturer Macherey-Nagel, the EC format fits standard HPLC systems used in research, quality control, and routine laboratory analysis. The short 50 mm bed combined with 1,8 µm particles supports efficient separations in a compact footprint, while the 4 mm internal diameter matches common analytical-scale flow paths. NUCLEODUR C18 Pyramid chemistry is selected where stable retention and well-defined peak shape are required under typical reversed-phase eluent conditions. The column is delivered ready for installation and is suited to method development as well as established HPLC procedures on complex sample matrices. Packaging comprises a single EC HPLC column for direct laboratory use.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about EC 50/4 NUCLEODUR C18 Pyramid, 1.8 µm
What is this article?
EC 50/4 NUCLEODUR C18 Pyramid, 1.8 µm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Colonnes HPLC, inside Colonnes HPLC & accessoires, in Chromatographie.
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.
