Description
EC 4/3 NUCLEOSIL 120-5 C8 is an HPLC guard column designed to shield analytical main columns during liquid chromatographic separations. It has a length of 4 mm and an internal diameter of 3 mm, and is filled with the NUCLEOSIL 120-5 C8 stationary phase for reversed-phase applications that rely on octyl-bonded silica chemistry. Placed ahead of the main column, the guard cartridge intercepts particulates and strongly retained sample constituents, helping to preserve efficiency, selectivity and operating pressure of the analytical column.
This article is part of HPLC columns, in HPLC columns & accessories.
The product is offered as a pack of three pieces from manufacturer Macherey-Nagel. EC 4/3 cartridges match main columns with 3, 4 or 4,6 mm internal diameter and must be installed in the Column Protection System guard column holder (REF 718966) to ensure a secure, low-dead-volume connection. Rapid cartridge replacement supports routine HPLC maintenance in research and quality-control laboratories without altering the established method geometry. This NUCLEOSIL C8 guard format is a practical choice wherever reliable pre-column protection and C8 phase compatibility are required.

Questions about EC 4/3 NUCLEOSIL 120-5 C8
What is this article?
EC 4/3 NUCLEOSIL 120-5 C8 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.
