Description
EC 4/3 NUCLEOSIL 120-5 C18 is an HPLC guard column for protecting analytical main columns in reverse-phase liquid chromatography. The cartridge is 4 mm long with a 3 mm internal diameter and contains NUCLEOSIL 120-5 C18 stationary phase. It is offered in packs of three pieces for use with main columns of 3, 4 or 4,6 mm internal diameter and requires the Column Protection System guard column holder (REF 718966). These EC-format precolumns from manufacturer Macherey-Nagel intercept particulates and strongly retained sample components before they enter the analytical bed, supporting stable separation performance and longer main-column service life. The compact EC 4/3 geometry fits common narrow-bore and standard analytical HPLC formats used in method development and routine analysis. Laboratories performing C18 reverse-phase work can integrate the cartridges into existing Column Protection System holders without modifying primary column dimensions. The three-piece pack enables continuous operation and simple scheduled replacement during instrument maintenance cycles.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEOSIL 120-5 C18
What is this article?
EC 4/3 NUCLEOSIL 120-5 C18 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.
