Description
HPLC column NUCLEODUR® SiOH is a preparative liquid-chromatography column with an unmodified silica (SiOH) stationary phase, 5 µm particle size and dimensions of 250 × 21 mm. Designed for high-performance liquid chromatography workflows, it supports separation tasks in environmental analysis and broader analytical laboratories where silica-based normal-phase or polar retention is required. The NUCLEODUR® geometry offers a practical balance of bed length and internal diameter for method development and preparative-scale work. Supplied as a single column unit and weighing approximately 0,386 kg, the product integrates readily into standard HPLC systems. This column is available from manufacturer MACHEREY-NAGEL for laboratories seeking a defined SiOH phase in the NUCLEODUR® range. Use it for routine and research liquid-chromatography applications that call for a 5 µm silica packing in a 250 × 21 mm format.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

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