Description
EC 4/3 NUCLEOSIL 300-5 C4 is an HPLC guard column cartridge with 4 mm length and 3 mm internal diameter, packed with NUCLEOSIL 300-5 C4 stationary phase. It is intended to protect matching analytical main columns by trapping particulates and strongly retained matrix components before they reach the primary bed. The cartridge is specified for main columns with 3, 4 or 4,6 mm internal diameter and requires a Column Protection System guard column holder for correct installation. Supplied in a pack of three pieces from manufacturer Macherey-Nagel, this EC-format guard supports routine reversed-phase HPLC work where C4 selectivity on a 300 Å, 5 µm NUCLEOSIL base is appropriate. Net weight is 0,02 kg per pack. Using a short EC 4/3 guard helps extend main-column lifetime and stabilise chromatographic performance in analytical laboratories handling complex samples, without changing the fundamental separation chemistry of the NUCLEOSIL 300-5 C4 system.

Questions about EC 4/3 NUCLEOSIL 300-5 C4
What is this article?
EC 4/3 NUCLEOSIL 300-5 C4 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.
