A pioneer of FT-ICR Mass Spectrometry, Alan G. Marshall (1944–2025), is best known for co-inventing Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), a transformative technique that enabled ultrahigh-resolution analysis of complex mixtures. Over a career spanning more than five decades at institutions like the University of British Columbia, The Ohio State University, and Florida State University, he published over 650 peer-reviewed papers and mentored more than 150 scientists. Marshall’s work profoundly impacted fields ranging from astrobiology to petroleomics and earned him numerous prestigious awards and fellowships. Revered for his intellect, mentorship, and dedication to science, he leaves behind a legacy that continues to shape modern mass spectrometry.
Market Profile: LC-MS Time-of-Flight Mass Spectrometry
May 1st 2009An oft-overlooked segment of the mass spectrometry market is time-of-flight LC–MS. Although LC-TOF does not possess the capabilities of more expensive mass spectrometry techniques, it fills an important price-to-performance segment of the market. The trickling down of technology and heavy competition are contributing to a strong market outlook for the area.
