Kubatova's Research Group
This research group focuses on speciation of complex mixtures to provide understanding of the mechanism of particular species’ formation, or their impact, or fate within specific materials/matrices.
To achieve this objective we develop analytical separation methods, typically with mass spectrometric detection. The areas of interest target understanding of the environment and renewable green technologies.
Our goal is to pursue such investigations using a top-to-bottom approach that is to determine the overall sample composition while developing and employing faster screening methods. This approach enables quantitative mass balance closure and determination of the role of individual species within a specific matrix. The methods used in our laboratory include liquid (LC) and gas chromatography (GC) with mass spectrometry (GC-MS) and other detectors. Most recently, we are also starting to use gel permeation chromatography for characterization of high molecular weight materials. In mass spectrometry, using our Time-of-Flight MS, we can conduct accurate mass measurements (typically up to two decimals or 10 ppm). An important aspect of our work is the development of preparation methods allowing for more effective approaches to comprehensive characterization.
The specific areas of research include:
- Biomass utilization and sustainable use; replacement of petrochemicals with renewable materials (lately being focused on the application to lignin)
- Atmospheric chemistry, especially detailed speciation of organics within particulate matter
- Characterization of biologically active species (relevant to industrial or medical applications)
- The fate of environmental pollutants
