Conclusions
Complex mixtures of semivolatiles can be resolved
on an Rtx®-5Sil MS column in a conventional 30m
x 0.25mm ID x 0.50µm configuration, without sac-
rificing the speed associated with shorter, thin
phase film columns, and with greater sample
capacity. Restek can provide the columns, reference
mixes, inlet and other accessories, and technical
help you need for reliable, problem-free analyses of
semivolatiles by US EPA or other methodology.
