Description
EC 4/3 NUCLEOSIL 300-5 C8 is an HPLC guard column designed to shield analytical main columns during liquid chromatography. It has a length of 4 mm and an internal diameter of 3 mm and is filled with NUCLEOSIL 300-5 C8 stationary phase for reverse-phase octyl separations. The product is supplied as a pack of three pieces for main columns with 3, 4 or 4,6 mm internal diameter and must be used with the Column Protection System guard column holder (REF 718966). These EC-format precolumns from manufacturer Macherey-Nagel trap particulate matter and highly retained sample constituents upstream of the analytical bed, helping preserve column performance over extended use. The EC 4/3 format matches widely used narrow-bore and standard analytical HPLC column IDs, so method transfer remains straightforward. Chromatographers working with C8-bonded silica can replace cartridges as part of regular maintenance without changing the primary column or holder. The three-unit pack supports continuous laboratory operation and convenient stock rotation in HPLC workflows.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEOSIL 300-5 C8
What is this article?
EC 4/3 NUCLEOSIL 300-5 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.
