Conclusions
The choice of a correct liner deactivation has hinged on
the
type of analytes
that
are
to
be
analyzed.
Typically,
if
the
analytes are acidic, a
liner tailored
to
have an acidic
character would be used in
order
to
avoid the possibility of
peak:
tailing or
adsorption. Conversely, a base deactivated liner would be selected
to
analyze
compounds with a basic character. This study has shown
that
liners with surface
characteristics which match those of
the
analytes
do
in fact give excellent analytical
performance
when
operating in their designated environments. However, the study
also shows that Siltek deactivated liners perform equivalently or better
than
the older
generation surfaces. Within
the
design of this comprehensive study, the Siltek
surface
is capable of
optimum
performance whether analyzing acidic semivolatile or
basic amine compounds.
