Beschreibung
EC 4/3 NUCLEOSIL ANION II is an HPLC guard column for protecting analytical main columns in liquid chromatography. It has a length of 4 mm and an internal diameter of 3 mm in the EC cartridge format and carries the NUCLEOSIL ANION II stationary phase chemistry used for anion-exchange separations. The unit is supplied as one piece and is intended for main columns with 3, 4 or 4,6 mm internal diameter. Use requires the Column Protection System guard column holder (REF 718966). By trapping particulates and strongly retained sample components ahead of the analytical bed, the short EC 4/3 geometry helps maintain column performance, peak shape and method robustness in routine HPLC work. Phase-matched guard protection is especially useful where anion selectivity must remain stable over extended sample sequences. This guard column from manufacturer Macherey-Nagel fits laboratories that already run NUCLEOSIL ANION II main columns and need a compact, dimensionally matched precolumn for continuous analytical operation without changing separation chemistry.

Questions about EC 4/3 NUCLEOSIL ANION II
What is this article?
EC 4/3 NUCLEOSIL ANION II 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 Chromatographie.
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.
