Description
HPLC column NUCLEODUR® C18 ec is a reversed-phase liquid chromatography column with C18 endcapped stationary phase, 5 µm particles and 250 × 21 mm dimensions. It is designed for high-performance liquid chromatography in laboratory environments covering environmental analysis and general liquid chromatography tasks. The C18 ec phase offers hydrophobic octadecyl bonding with endcapping for separation of organic analytes under reversed-phase conditions. Delivered as 1 pc and weighing 1,415 kg, the column matches HPLC systems configured for this length and internal diameter. This NUCLEODUR® HPLC column from manufacturer MACHEREY-NAGEL forms part of a recognised silica-based column range used across chromatography laboratories. With 5 µm particle size, 250 mm length and 21 mm diameter, it supports routine separations, method development and preparative-oriented liquid chromatography where C18 ec selectivity is specified. Typical use contexts include environmental analysis workflows and broader HPLC practice. The single-unit pack is ready for mounting in compatible liquid chromatography equipment based on the stated geometry and stationary-phase designation.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about HPLC column NUCLEODUR®, C18 ec, 5µm, 250x21mm, 1 unit(s)
What is this article?
HPLC column NUCLEODUR®, C18 ec, 5µm, 250x21mm, 1 unit(s) 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.
