Description
EC 4/3 NUCLEODUR C18 Gravity is an HPLC guard column featuring 1,8 µm particles for effective protection of analytical reversed-phase columns. With a length of 4 mm and an internal diameter of 3 mm, it is matched to main columns of 3 mm, 4 mm or 4,6 mm ID. The pack contains three cartridges, allowing convenient replacement during routine method work. By trapping particulates and highly retained matrix components upstream of the analytical bed, the guard column helps maintain efficiency and peak shape over longer sequences. The NUCLEODUR C18 Gravity chemistry from manufacturer Macherey-Nagel provides a consistent C18 surface aligned with corresponding analytical columns of the same phase. Use requires the Column Protection System guard column holder (REF 718966). The EC 4/3 format offers a practical balance of low extra-column volume and robust protection for mid-bore HPLC systems in research and quality-control laboratories.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODUR C18 Gravity, 1.8 µm
What is this article?
EC 4/3 NUCLEODUR C18 Gravity, 1.8 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.
