With this silica gel, Macherey-Nagel has succeeded in developing a contemporary product that is ideally suited as a base material for modern HPLC phases. Here you will find our range of Nucleodur® silica gels and HPLC columns in the WICOM Shop

Innovation in the separation process - NUCLEOSHELL® from Macherey-Nagel

The demands placed on HPLC methods - especially with regard to the expected separation performance and the required detection limits - have risen steadily in recent years. In addition, the time required for an average analysis has increased significantly. The development of core-shell technology has set new standards for increasing efficiency in research and quality assurance. With the NUCLEOSHELL® product range, Macherey-Nagel offers novel silica gel phases based on the core-shell method. The special properties of NUCLEOSHELL® silica gels: solid core of silica; uniform shell of porous silica gel; high pressure stability up to 600 bar; significantly increased efficiency compared to traditional, fully porous separation phase materials; can also be used on conventional LC systems (due to reduced back pressure); Physical data: Pore size 90 Å; particle size 2.7 µm (core 1.7 µm); specific surface area 130 m2/g
