Description
EC 4/2 NUCLEODUR PFP, 5 µm is an HPLC guard column intended to protect narrow-bore analytical main columns during liquid chromatography. The precolumn has a length of 4 mm and an internal diameter of 2 mm, and is filled with 5 µm NUCLEODUR PFP packing. It is offered in a pack of 3 pieces and is specified for main columns with 2 mm internal diameter. Use requires the Column Protection System guard column holder (REF 718966). This EC 4/2 NUCLEODUR PFP guard column from manufacturer Macherey-Nagel matches EC-format HPLC systems that employ 2 mm ID main columns and PFP phase chemistry. Positioned before the analytical column, the short guard bed supports retention of particulates and strongly retained sample constituents. The 4 mm length and 2 mm ID geometry are aligned with narrow-bore EC column configurations used in method work and routine separations. Laboratories operating HPLC with 2 mm ID main columns can mount these precolumns in the designated holder for consistent guard-column protection within the EC Column Protection System.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/2 NUCLEODUR PFP, 5 µm
What is this article?
EC 4/2 NUCLEODUR PFP, 5 µm 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.
