Description
EC 4/3 NUCLEOSIL 100-7 C2 is an HPLC guard column (precolumn) for protecting analytical separation columns in liquid chromatography systems. The short cartridge has a length of 4 mm and an internal diameter of 3 mm and is filled with NUCLEOSIL 100-7 C2 stationary phase in the EC 4/3 format. Mounted upstream of the main column, it provides a sacrificial bed that can capture particulates and strongly retained matrix components, helping preserve the integrity and lifetime of the analytical packing during routine sample sequences. Units are supplied three per pack and are intended for main columns with 3 mm, 4 mm or 4,6 mm internal diameter. Operation requires the Column Protection System guard column holder (REF 718966), which must be obtained separately. These EC-format guard columns from manufacturer Macherey-Nagel offer laboratories a compact, replaceable precolumn option aligned with NUCLEOSIL 100-7 C2 chemistry and standard analytical column internal diameters.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEOSIL 100-7 C2
What is this article?
EC 4/3 NUCLEOSIL 100-7 C2 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC columns, inside HPLC columns & accessories, in Chromatography equipment.
An HPLC column is specified by the stationary phase, the particle size, the length and the internal diameter. A C18, 5 µm, 150 × 4.6 mm column is a different article from a C18, 3 µm, 100 × 2.1 mm column. The smaller bore belongs on a lower flow. A column has a direction and a pH range.
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.
