个人简介
The nature and significance of my scholarship is directed toward the development of intelligent chemical instruments. I am working with ion mobility spectrometry (IMS) and mass spectrometry (MS). These two methods are complementary and are distinguished by the pressure at which the ion measurement is made. If the ion velocities are measured in the gas phase at atmospheric pressure, the ion mobility is determined by an ion's volume-to-charge ratio. If the ions are measured under vacuum conditions (i.e., less than a millionth of atmospheric pressure) then their velocity is determined by the mass-to-charge ratio of the ion. Because ion mobility spectrometers do not require a vacuum system, they are more portable, less costly, more rugged, and amenable to miniaturization. Mass spectrometers have the advantages of greater resolving and informing power when compared to ion mobility spectrometers.
