Description
EC 4/2 NUCLEODUR C18 HTec, 5 µm is an HPLC guard column developed to shield narrow-bore analytical main columns during reversed-phase separations. It has a length of 4 mm and an internal diameter of 2 mm, and is filled with NUCLEODUR C18 HTec material at a 5 µm particle size. The cartridge is specified for main columns with 2 mm internal diameter and must be used with the Column Protection System guard column holder (REF 718966). Supplied in packs of 3 pieces from manufacturer Macherey-Nagel, these guard columns help prolong the service life of valuable HPLC columns by capturing particles and strongly retained sample components upstream of the analytical bed. The C18 HTec phase is suited to robust reversed-phase applications under typical laboratory HPLC conditions. A practical choice for microbore and 2 mm-ID workflows where reliable precolumn protection, simple cartridge handling and reproducible chromatographic performance are required day to day.

Questions about EC 4/2 NUCLEODUR C18 HTec, 5 µm
What is this article?
EC 4/2 NUCLEODUR C18 HTec, 5 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.
