Description
EC 4/3 NUCLEODUR C18 PAH is an HPLC guard column with 3 µm particles, intended to shield analytical main columns during reversed-phase work on polycyclic aromatic hydrocarbons and related compounds. The cartridge has a length of 4 mm and an internal diameter of 3 mm, and is specified for main columns with 3, 4 or 4,6 mm ID. Packaged as three pieces per unit, the guard columns help retain particulates and strongly adsorbed matrix material, supporting longer analytical column service life and more stable chromatography. The NUCLEODUR C18 PAH stationary phase from manufacturer Macherey-Nagel is designed to match corresponding analytical columns of the same chemistry, aiding consistent selectivity. Use requires the Column Protection System guard-column holder (REF 718966). Defined particle size, EC format and broad ID compatibility make this precolumn a practical option for laboratories that need dependable column protection in routine and method-development HPLC applications.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODUR C18 PAH, 3 µm
What is this article?
EC 4/3 NUCLEODUR C18 PAH, 3 µm 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.
