Description
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.
