Description
EC 4/2 NUCLEODUR C18 HTec is an HPLC guard column packed with NUCLEODUR C18 HTec material at a particle size of 3 µm. The cartridge measures 4 mm in length with an internal diameter of 2 mm and is intended for analytical main columns with 2 mm internal diameter. Supplied as a pack of three pieces, it requires the Column Protection System guard column holder (REF 718966) for installation. This EC-format precolumn from manufacturer Macherey-Nagel is designed for HPLC chromatography setups that use matching 2 mm ID main columns. Length, internal diameter and particle size follow the EC 4/2 designation so the guard segment seats correctly in the specified holder. The three-piece pack supports successive replacement of the guard element during ongoing liquid chromatography work while the main column remains in place. It suits laboratories organising column protection around the Column Protection System platform for narrow-bore reversed-phase HPLC with NUCLEODUR C18 HTec chemistry at 3 µm particle size.
This article is part of HPLC columns, in HPLC columns & accessories.

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