Description
EC 4/2 NUCLEODUR 300-5 C4 ec is an HPLC guard column (precolumn) for protecting analytical main columns in liquid chromatography systems. It offers a length of 4 mm and an internal diameter of 2 mm and is intended for main columns with 2 mm ID. The cartridge contains the NUCLEODUR 300-5 C4 ec stationary phase, a C4 endcapped packing chosen for reversed-phase applications where less hydrophobic retention than C18 is preferred. Supplied as a pack of three pieces, the guard cartridges require the Column Protection System guard column holder (REF 718966). Positioned before the analytical column, they help retain particulates and strongly retained sample constituents, supporting consistent efficiency, peak integrity and pressure behaviour. This EC-format guard column from manufacturer Macherey-Nagel is suited to pharmaceutical, chemical and research laboratories running narrow-bore 2 mm ID HPLC methods. Compact geometry keeps extra-column contribution low while extending the usable life of the main column.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR 300-5 C4 ec
What is this article?
EC 4/2 NUCLEODUR 300-5 C4 ec 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.
