Description
EC 4/3 NUCLEOSIL 100-5 CN is an HPLC guard column for protecting analytical main columns in liquid chromatography. It has a length of 4 mm and an internal diameter of 3 mm and is packed with NUCLEOSIL 100-5 CN stationary phase. The cyano-bonded silica helps retain particulates and strongly adsorbed matrix components before they reach the primary separation bed, supporting longer analytical column lifetime and more stable chromatographic performance. Each pack contains 3 pieces and is intended for main columns with 3, 4 or 4,6 mm internal diameter. Use requires the Column Protection System guard column holder (REF 718966). This EC 4/3 format from manufacturer Macherey-Nagel fits routine HPLC workflows where reliable precolumn protection is needed for moderately polar analytes under normal-phase or reversed-phase conditions. The compact cartridge design makes replacement straightforward during method maintenance and helps reduce unplanned downtime caused by fouled analytical columns in research and quality-control laboratories.

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