Description
EC 4/2 NUCLEODUR C18 ISIS is an HPLC guard column with 3 µm particles, designed to safeguard analytical main columns in liquid chromatography systems. The cartridge measures 4 mm in length with a 2 mm internal diameter and is matched to main columns of 2 mm ID. Supplied in packs of three, these guard columns capture particulates and strongly retained sample species before they enter the analytical bed, helping extend column lifetime and protect chromatographic performance. The NUCLEODUR C18 ISIS stationary phase delivers reversed-phase C18 selectivity for pharmaceutical, environmental and research HPLC methods. Cartridges from manufacturer Macherey-Nagel require the Column Protection System guard column holder (REF 718966) for proper installation. The EC 4/2 format aligns with standard EC column hardware and is specified for use with 2 mm ID main columns. Correctly mounted, the guard column supports reliable routine operation by limiting mechanical and chemical stress on the primary packing while maintaining consistent flow and separation behaviour.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR C18 ISIS, 3 µm
What is this article?
EC 4/2 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.
