Selectivity LiChrospher/Superspher

LiChrospher, Superspher, and Purospher e show similar selectivity patterns because of the similar high degree of coverage and the presence of polar groups on the surface. The doubtless existent metal ions and free silanol groups on the surface of LiChrospher and Superspher have no effect in this case. Also similar are Symmetry and Zorbax ODS, two phases that are markedly different in the case of the separation of ionic analytes. 

The similarity of the Cg phases LiChrospher Select B, Superspher Select B, and Zorbax SB Cg is clearly evident...

Our opinion Also think about, for example, Hypersil ODS, LiChrospher Select B 60, Superspher or Cosmosil NAP additionally, for example, Jupiter, Zorbax SB 300 as well as Nucleosil 50 - then orthogonality is given for all cases. 

As is known, liChrospher and Superspher are essentially identical, the only difference being in their partide size (5 im compared to 4 im). The hexagons are nearly identical. In the case of LiChrospher Select B and Superspher Select B, they are again nearly the same.
