Group IVB metallocene poly(ether ester) polymers containing alpha-cyano-4-hydroxycinnamic acid that act as self-matrix materials in MALDI MS

Polymers derived from reacting Group IVB metallocene dihalides and the matrix alpha-cyano-4-hydroxycinnamic acid act as their own matrix agent when performing MALDI MS. Ion fragments containing two repeat units and greater are formed. The results are similar to those obtained employing graphite as the matrix material. The advantage of employing graphite as a comparative standard is that non-interfering ion fragment clusters are not produced by...
