Description
EC 4/3 NUCLEOSHELL Biphenyl, 2,7 µm is an HPLC guard column designed to shield analytical columns during liquid chromatography. Measuring 4 mm in length with a 3 mm internal diameter, it is specified for main columns with 3, 4 or 4,6 mm ID. The NUCLEOSHELL Biphenyl stationary phase at 2,7 µm particle size delivers biphenyl-type selectivity while the compact EC precolumn format helps retain particulates and aggressive sample components. Supplied in packs of 3 pieces, installation requires the Column Protection System guard column holder (REF 718966). This configuration from manufacturer Macherey-Nagel suits standard-bore HPLC setups where protecting the analytical bed supports consistent retention, peak shape and system pressure. It is a practical choice for laboratories running biphenyl-phase methods in research, method development and routine analysis.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEOSHELL Biphenyl, 2.7 µm
What is this article?
EC 4/3 NUCLEOSHELL Biphenyl, 2.7 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.
