SMT C18可能比Zorbax SB-C18/Waters Sym-C18/Hypeisil-C18更好的柱子

Important Information about of
SMT SAM-Columns


It is very important to point out that SMT-C18
columns as well as all the other columns
introduced in this catalog are unique in their
applications; while in most cases , the columns
may show relatively similar selectivities when
compared with other commercially available, for
example, other C18 columns in the market,
subtle differences in separation of most
complex molecules are often possible. All SMT
columns contain mixed ligands that are
necessary for the extremely high stability and
surface coverage. Furthermore, utilization of
SAM technology in the manufacturing process
automatically ensures true base-deactivated.
This fact is demonstrated by the
chromatograms of an organic cation, Ru(bpy)3
2+
on SMT SAM-C18 and some competitors’
columns.
