Description
EC 4/3 NUCLEOSIL 100-5 C18 PAH is an HPLC guard column configured to protect analytical columns used in polycyclic aromatic hydrocarbon and related reversed-phase separations. The cartridge has a length of 4 mm and an internal diameter of 3 mm and is packed with NUCLEOSIL 100-5 C18 PAH stationary phase, so the protective bed chemistry corresponds to C18 PAH-type main columns. Units are supplied in packs of three for scheduled exchange during method sequences. These EC 4/3 guard columns fit main columns with 3, 4 or 4,6 mm internal diameter and require the Column Protection System guard column holder (REF 718966) for correct installation. In HPLC practice, a phase-matched guard column retains particulates and highly retained matrix components before they enter the analytical column, helping preserve peak shape, back-pressure stability and column lifetime. This NUCLEOSIL 100-5 C18 PAH EC 4/3 option from manufacturer Macherey-Nagel is aimed at laboratories running PAH-oriented or comparable C18 methods that need a short, replaceable upstream protection element without large extra-column volume. The compact EC format supports straightforward maintenance of analytical HPLC setups.

Questions about EC 4/3 NUCLEOSIL 100-5 C18 PAH
What is this article?
EC 4/3 NUCLEOSIL 100-5 C18 PAH 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.
