Description
EC 4/2 NUCLEODUR C8 Gravity, 5 µm is an HPLC guard column for analytical liquid chromatography. The cartridge measures 4 mm in length with an internal diameter of 2 mm and uses NUCLEODUR C8 Gravity stationary phase at a particle size of 5 µm. Each pack contains 3 pieces from manufacturer Macherey-Nagel for laboratories working with reversed-phase HPLC on C8 Gravity chemistry. It is intended for main columns with 2 mm internal diameter and requires the Column Protection System guard column holder (REF 718966). In the EC format, this short precolumn is placed upstream of the analytical column so guard and main column can share the same NUCLEODUR C8 Gravity phase. Length, internal diameter and particle size follow the EC 4/2 geometry used with corresponding narrow-bore analytical columns. Supplied as three cartridges per pack, the product supports regular exchange of the guard element in routine HPLC work and fits analytical setups that already employ NUCLEODUR C8 Gravity columns with 2 mm internal diameter.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR C8 Gravity, 5 µm
What is this article?
EC 4/2 NUCLEODUR C8 Gravity, 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.
