Description
EC 4/3 NUCLEODUR 100-3 is an HPLC guard column designed to protect analytical main columns during liquid chromatography. The cartridge measures 4 mm in length with a 3 mm internal diameter and uses NUCLEODUR 100-3 packing. It is specified for main columns with 3, 4 or 4,6 mm internal diameter and must be installed in the Column Protection System guard column holder (REF 718966). Delivered as a pack of three units from manufacturer Macherey-Nagel, the EC 4/3 format allows the protective segment to be replaced while the main column stays in the system. Guard columns of this type sit ahead of the analytical bed to retain particulates and strongly adsorbed matrix constituents, supporting stable operation in routine HPLC sequences. Laboratories that already employ NUCLEODUR 100-3 chemistry on the main column can match the guard phase for consistent selectivity at the inlet. The short EC geometry is suited to standard HPLC instrumentation where column protection is handled as a dedicated consumable. This three-piece pack provides multiple replacement cartridges for ongoing analytical and method-development work.

Questions about EC 4/3 NUCLEODUR 100-3
What is this article?
EC 4/3 NUCLEODUR 100-3 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.
