Goo refers to macromolecular
materials, typically biomolecular, which are involatile due to aggregate
the Dept.
of Chemistry and Biochemistry at Arizona
State University.
We specialize in mass spectrometric methods for the analysis of
involatile materials.
These can be separated into two distinct classes: Rocks
and Goo.
Under Rocks
we classify covalently or ionically bonded materials such as minerals,
metals, semiconductors, ceramics. The information required is typically
elemental composition, in particular trace element and impurity composition,
ideally spatially localized. The analytical technique used is Secondary
Ion Mass Spectrometry (SIMS). For further information on SIMS, please

]
non-covalent interactions between molecules. The information
required is molecular mass, identity and amount.
We utilize the techniques of Matrix-Assisted Laser Desorption/Ionization(MALDI)
and
Electrospray Ionization (ESI) Time-of-flight Mass Spectrometry
to study a broad range ofbiological
and synthetic molecules. We have also developed a new technique:
Impact Desolvation of Electrosprayed Microdroplets (IDEM) which may have
some advantages for analysis of biomolecular mixtures,
particularly DNA. The laboratory is located in the basement
of the Physical Sciences Building, Room D60.
