Description
EC 4/3 NUCLEODEX BETA-PM is an HPLC guard column (precolumn) with a bed length of 4 mm and an internal diameter of 3 mm. It is supplied as a single cartridge and is intended for use with analytical main columns of 3, 4 or 4,6 mm internal diameter. Mounting requires the Column Protection System guard column holder (REF 718966), which is ordered separately. Positioned upstream of the analytical column, this EC 4/3 format cartridge helps retain particulates and strongly retained sample components before they reach the main packing bed, supporting longer service life of the primary HPLC column. The NUCLEODEX BETA-PM phase from manufacturer Macherey-Nagel is offered in this compact guard geometry for laboratories that already run matching analytical columns or that need a dedicated precolumn in the EC 4/3 format. The short 4 mm path length keeps extra-column volume low while still providing a practical first line of column protection in routine liquid chromatography. One piece is supplied per pack, ready for installation once the specified holder is in place on systems configured for 3 to 4,6 mm ID columns.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEODEX BETA-PM
What is this article?
EC 4/3 NUCLEODEX BETA-PM 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.
