Finding the Source
We catch up with Jacob Shelley, Professor at Rensselaer Polytechnic Institute, about the most exciting new advances in spectroscopy and mass spectrometry – including his group’s quest for better ionization sources.
Matthew Hallam | | Interview
What is the focus of your research?
I would say that we have two main branches of research. First, we want to speed up analysis, largely by producing portable mass spectrometry (MS) instrumentation. Second, we are developing ‘smart’ automated data processing tools that use algorithms to extract useful information from spectra. We are also working towards developing a ubiquitous ionization source that can be used to detect elemental species, small molecules and large biopolymers; these systems could fragment molecules to obtain structural information and then break it down even further to look at atomic ions. We have actually accomplished this using an ionization source called solution-cathode glow discharge (SCGD).
