Description
EC 125/3 NUCLEODUR C18 PAH, 3 µm is an EC HPLC separation column for high-performance liquid chromatography applications. It is built with a NUCLEODUR C18 PAH stationary phase, a particle size of 3 µm, a column length of 125 mm and an internal diameter of 3 mm. These dimensions specify the EC 125/3 analytical format. Supplied as a single column per pack, it is intended for installation in matching HPLC systems. NUCLEODUR C18 PAH chemistry from manufacturer Macherey-Nagel supports reverse-phase separations that take advantage of a C18 phase oriented toward polycyclic aromatic hydrocarbon analysis. Laboratories apply such columns in method development, routine assays and quality-control workflows where consistent retention and peak shape are important. The 3 µm particles promote efficient mass transfer at typical analytical flow rates, while the 125 mm length extends the separation path relative to shorter EC formats, aiding resolution when needed. The 3 mm internal diameter fits modern HPLC instruments running at moderate flows. This EC HPLC column is suited to professional chromatography laboratories that require dependable C18 PAH selectivity in a 125 mm × 3 mm configuration.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

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