Description
EC 4/3 NUCLEODUR C18 ISIS, 3 µm is an HPLC guard column (precolumn) designed to protect analytical main columns in reversed-phase liquid chromatography. The cartridge measures 4 mm in length with a 3 mm internal diameter and is packed with NUCLEODUR C18 ISIS stationary phase at a 3 µm particle size, matching the selectivity of corresponding analytical columns. Supplied as a pack of three pieces, these guard columns are intended for use with main columns of 3, 4 or 4,6 mm internal diameter. Installation requires the Column Protection System guard column holder (REF 718966). By trapping particulates and strongly retained matrix components before they reach the analytical bed, the EC 4/3 format helps maintain peak shape, retention stability and column lifetime in routine HPLC workflows. The NUCLEODUR C18 ISIS chemistry from manufacturer Macherey-Nagel supports demanding separations where steric selectivity and robust C18 performance are required. Suitable for method development and quality-control laboratories that standardise on 3 µm NUCLEODUR C18 ISIS main columns and need a matched, short guard segment for continuous system protection.
This article is part of HPLC columns, in HPLC columns & accessories.

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