Description
EC 4/3 NUCLEOSIL 50-5 C18 ec is an HPLC guard column designed to protect C18 analytical main columns in reversed-phase liquid chromatography. The cartridge length is 4 mm with an internal diameter of 3 mm and is filled with NUCLEOSIL 50-5 C18 ec material in the EC 4/3 format. Installed upstream of the separation column, it traps particulates and highly retained matrix species before they reach the primary packing, helping to stabilise backpressure and prolong main-column service life. The guard is specified for main columns with 3 mm, 4 mm or 4,6 mm internal diameter and must be used with the Column Protection System guard column holder (REF 718966). Supplied as a pack of three pieces from manufacturer Macherey-Nagel, it suits laboratories running NUCLEOSIL C18 ec methods that need matched inlet protection without altering the established selectivity. The endcapped C18 chemistry of the guard aligns with common reversed-phase workflows in pharmaceutical, environmental and chemical analysis. Compact EC 4/3 geometry allows straightforward integration into existing HPLC systems wherever short precolumns are preferred for routine column safeguarding.

Questions about EC 4/3 NUCLEOSIL 50-5 C18 ec
What is this article?
EC 4/3 NUCLEOSIL 50-5 C18 ec is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC guard columns, inside HPLC columns & accessories, in Chromatography equipment.
A guard column is a short column of the same phase as the analytical column, placed in front of it to catch particles and compounds that would stick forever. It is meant to be replaced. A guard of a different phase changes the separation. The holder and the cartridge are often separate parts.
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.
