NUCLEODUR® high purity silica phases for HPLC

 


 

Macherey-Nagel are world famous for their Nucleodur and Nucleosil materials yet also offer a wide range of other HPLC Columns and Accessories to meet all of you HPLC requirements.

  • Key features of MN HPLC products are highly pure and selective media ensuring increased separation efficiency and selectivity
  • innovative bonding chemistries allowing special separations and many particle sizes to conform with the scale of the separation you require.

 

Characterization:

NUCLEOSIL® is a family of totally porous spherical silicas with a very pure and uniform SiO2 structure 

Wide acceptanRem-Nucleosilce as routine packings for very different fields of chromatography

 

One of the first spherical silicas used in HPLC

 

Developed in the early seventies, it became a world-renowned HPLC packing

 

Still found in many analytical and preparative applications

 

An absolutely reliable choice in HPLC

 

The largest variety of modified HPLC silicas available
