Description
EC 4/2 NUCLEODUR PolarTec, 5 µm is an HPLC guard column with a length of 4 mm and an internal diameter of 2 mm, packed with 5 µm NUCLEODUR PolarTec phase. This EC-format precolumn is intended for HPLC main columns with a 2 mm internal diameter. Installation requires the Column Protection System guard column holder (REF 718966). Offered as a pack of three pieces from manufacturer Macherey-Nagel, the cartridges suit HPLC chromatography systems that use matching NUCLEODUR PolarTec analytical columns in the 2 mm ID format. The EC 4/2 geometry provides a short 4 mm bed of 5 µm PolarTec material for placement ahead of the main column when fitted in the specified holder. Laboratories running 2 mm ID main columns can replace the guard element as required while keeping the NUCLEODUR PolarTec phase designation consistent. Each pack contains three EC 4/2 cartridges measuring 4 mm in length and 2 mm in internal diameter, prepared for use with Column Protection System holder REF 718966 in routine HPLC applications based on this stationary phase.
This article is part of HPLC columns, in HPLC columns & accessories.

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