“…Petroleum is one of the most complex mixtures on the planet, and unraveling that complexity has long stood as a challenge for analytical and molecular characterization science. The 150 years of research, from physical property measurements in the 19th century and simple chromatography in the early 20th century to Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry and petroleomics in recent decades, have tremendously advanced our mastery of this complexity and helped us produce today’s fuels and chemicals. , As we move forward into advanced materials and new products, we need to broaden our analyses to a more accurate understanding of molecular structures and their chemical reactivities. − …”
