Dear All

What is the alternative column for symmetry shield.
My problem is, i worked for one molecule on this coolumn and i got better peak shape . But i used other columns like C8, C8, Phenyl and Cyano columns i donot getting peak shape at all. Finallly i got good peak shape only in symmetry shield.

As one of the designers of the SymmetryShield phase, I can tell you that the primary feature was to get good peak shapes for many or most analytes, better than the classical junk. This agrees with your experience, and I am glad that this is so. Then why are you looking for an alternative?

Hello Ramesh,

What are you analyzing? Is it hydrophobic basic compound, which gives you tailing?
