Description
EC 4/3 NUCLEODUR 100-5 CN is an HPLC guard column (pre-column) designed to protect analytical main columns during liquid chromatography. With a length of 4 mm and an internal diameter of 3 mm, the cartridge is specified as NUCLEODUR 100-5 CN and is delivered in a pack of three pieces. It is intended for use with main columns of 3, 4 or 4,6 mm internal diameter and requires the Column Protection System guard column holder (REF 718966). Offered by manufacturer Macherey-Nagel, this EC-format pre-column sits ahead of the analytical bed to intercept particulates and strongly retained sample constituents that could otherwise impair the main column. The NUCLEODUR 100-5 CN designation supports phase-matched guard protection in HPLC methods that employ the corresponding CN chemistry on the analytical column. Compact EC 4/3 geometry suits standard laboratory column-protection practice for 3 to 4,6 mm ID systems. A three-piece pack provides convenient spare cartridges for replacement during routine analysis, method setup or continuous operation, helping maintain stable chromatographic conditions on the protected main column.
This article is part of HPLC columns, in HPLC columns & accessories.

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