Description
EC 4/3 NUCLEOSIL 100-5 N(CH3)2 is an HPLC guard column (precolumn) designed to protect analytical HPLC main columns in routine liquid chromatography. The cartridge format measures 4 mm in length with a 3 mm internal diameter and is packed with NUCLEOSIL 100-5 N(CH3)2 stationary phase, matching common dimethylamino-type separations. Supplied as a pack of three pieces, these EC 4/3 guard columns are intended for use with main columns of 3, 4 or 4,6 mm internal diameter. Installation requires the Column Protection System guard column holder (REF 718966), which is ordered separately. In HPLC workflows, a correctly matched guard column helps retain particulates and strongly retained matrix components before they reach the analytical bed, supporting stable retention behaviour and extending the service life of the main column. This EC 4/3 NUCLEOSIL 100-5 N(CH3)2 configuration from manufacturer Macherey-Nagel is suited to laboratories that already run NUCLEOSIL-based methods and need a compact, replaceable upstream protection element. The short bed length keeps extra-column volume low while still providing a practical protective barrier for day-to-day sample sequences in analytical HPLC.

Questions about EC 4/3 NUCLEOSIL 100-5 N(CH3)2
What is this article?
EC 4/3 NUCLEOSIL 100-5 N(CH3)2 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.
