Description
EC 4/2 NUCLEOSIL 100-5 C18 PAH is an HPLC guard column with 4 mm length and 2 mm internal diameter, packed with NUCLEOSIL 100-5 C18 PAH stationary phase. It is intended for main columns with 2 mm ID and requires a Column Protection System guard-column holder (REF 718966) for installation. Supplied in a pack of 3 pieces from manufacturer Macherey-Nagel, these short guard cartridges help protect the analytical column from particulate matter and strongly retained sample components during PAH-oriented reversed-phase separations. The C18 PAH bonding chemistry is selected for polycyclic aromatic hydrocarbon work and related hydrophobic analytes where phase selectivity and column lifetime matter. Compact EC 4/2 format keeps extra-column volume low while still providing an exchangeable first barrier ahead of the main column. Laboratories running narrow-bore HPLC methods can replace guard segments routinely without disturbing the primary NUCLEOSIL separation column. Consistent dimensions and phase designation support method transfer and preventive maintenance schedules in environmental, food and research chromatography.

Questions about EC 4/2 NUCLEOSIL 100-5 C18 PAH
What is this article?
EC 4/2 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.
