Danese Stahl is involved in the research of the biofuel products in a collaborative project with Chemical Engineering to provide necessary information regarding the identification and quantification of biofuel components. This information is important in adjusting the engineering techniques designed for generation of these fuels.
Analytical techniques employed involve gas chromatography separation coupled with flame ionization and mass spectrometry detection (GC/FID and GC/MS). The lab has just acquired a new Agilent 7890A GC with PTV injector and multiple detection (TCD, FID, MSD) capability. For additional information about this project, contact Danese Stahl.
I come from the capital of the Czech Republic, Prague. I have received my master’s degree in Food Science and Technology at the Institute of Chemical Technology in Prague in 2006.
My main research project involves method development for biofuel determination and quantification using GC-FID-MS. I am also working on valuable by-products extraction from biofuels and on method development for their identification and quantification using LC and LC-MS.

I am originally from the Czech Republic. I obtained M.S. degree at the Institute of Chemical Technology, Prague, Czech Republic with specialization in Biochemistry and Biotechnology.
Currently, I am working on a detailed chemical characterization of air particulate matter. To elucidate processes and reactions occuring in the atmosphere, a chemical composition of complex particulate matter samples has to be determined. I am particularly interested in polar organic species such as carboxylic acids, aldehydes and their oligomers. Advanced analytical instrumentation including GC-MS, SPME-GC-MS, LC-MS is employed in analysis.
I also maintain the departmental high resolution time-of-flight mass spectrometer. My work is to ensure the proper working order and calibration of the instrument as well as help students measure their samples.

I am a graduate student from Minnesota currently in my second year of graduate school. I also did my undergraduate studies in chemistry at UND. I currently do research on organic carbon content and polarity distribution in various types of particulate matter.
I am involved in collecting and characterizing atmospheric samples using our PM2.5 sampler and also in carbon determination in the NASA DC-8 samples. I am also working on development of extraction methods and some specific compound speciation.

My name is Inna Eduardovna Popova Tyapochkin the Great. I was a graduate student at Chemistry Department, UND, Grand Forks, ND, USA.
I worked on the development of a new sensitive and reliable analytical method for extraction and quantification of lignans in flaxseed. Lignans are biologically active antioxidative compounds that may help to cure diabetes and cardiovascular diseases. Besides, they were shown to be effective against cancer.
This project is particularly important for North Dakota because this state is one of the main flax producers in the U.S. An increase in flax consumption may have not only a positive impact on human health but also on domestic economy.
This project was supported by NSF EPSCoR Infrastructure Improvement Program and DOE EPSCoR Infrastructure Improvement Program DOE Biomass Utilization.
