Description
EC 4/2 NUCLEODUR 300-5 C18 ec is an HPLC guard column (precolumn) for protecting analytical main columns in liquid chromatography. It has a length of 4 mm and an internal diameter of 2 mm and is intended for main columns with 2 mm ID. The cartridge is packed with the NUCLEODUR 300-5 C18 ec stationary phase, a C18 endcapped material suited to reversed-phase HPLC where sample matrix and particulates can shorten column life. Units are supplied in a pack of three and must be used with the Column Protection System guard column holder (REF 718966). Placed upstream of the analytical column, the guard bed retains strongly retained components and debris, helping preserve efficiency, peak shape and system pressure stability. This EC-format guard column from manufacturer Macherey-Nagel fits routine method protection in pharmaceutical, chemical and research laboratories that run narrow-bore 2 mm ID columns. Compact dimensions keep extra-column volume low while supporting reliable day-to-day HPLC operation.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR 300-5 C18 ec
What is this article?
EC 4/2 NUCLEODUR 300-5 C18 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.
