Description
EC 4/3 NUCLEODUR C18 Gravity-SB, 5 µm is an HPLC guard column for protecting analytical main columns in liquid chromatography. It has a length of 4 mm and an internal diameter of 3 mm, and uses the NUCLEODUR C18 Gravity-SB stationary phase with 5 µm particles. The EC-format precolumn is supplied in a pack of three pieces and is intended for main columns with 3, 4 or 4,6 mm internal diameter. It requires a Column Protection System guard-column holder (REF 718966) for installation. Offered by manufacturer Macherey-Nagel, this guard cartridge helps retain particulates and strongly retained matrix components before they reach the analytical bed, supporting stable reversed-phase separations and longer main-column lifetime. The compact EC 4/3 geometry fits standard column-protection hardware used on many HPLC systems in routine analytical laboratories. Suitable for method development and day-to-day sample analysis where C18 Gravity-SB selectivity is already established on the primary column.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODUR C18 Gravity-SB, 5 µm
What is this article?
EC 4/3 NUCLEODUR C18 Gravity-SB, 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.
