FTMS tackles synthetic polymers Despite their commercial value, analytical methods for studying synthetic polymers often seem to be overshadowed by work on biopolymers. Fred McLafferty and colleagues from Cornell University—no strangers to bioanalysis—turn their attention to analyzing glycol copolymers and use FTMS to separate and analyze sequence-specific ions, some of which have
