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.
The authors discuss progress in near-field IR microspectroscopy using a photothermal probe and show how it can be applied to the spectroscopic characterization of real-world samples.

Source Design and the Utility of Multimode Ionization (PDF)
January 1st 2004The author discusses how the physical realm of the atmospheric ionization source -- materials, gas, and heat dynamics -- and manipulating the ionization modes themselves perhaps are the current forefront of technological innovation.
This article is the third installment in a series about a novel spectrofluorometric method that allow for in vivo observation of the division of chlorplast populations in leaves of Arabidopsis thalania.
Processing Techniques for Handling Multiple Spectra (PDF)
November 1st 2003The author discusses several mathematical processing methods for handling, assessing, and studying groups containing multiple spectra. The processing techniques feature standard mathematical tools that are used to study a series of numerical results.
Rays of Hope: Spectroscopy as an Emerging Tool for Cancer Diagnostics and Monitoring (PDF)
October 1st 2003Vibrational and fluorescence spectroscopy, laser light-scattering techniques, and other optics-based approaches are gaining momentum in the quest for early detection and more effective treatment of cancer.
Pharmaceutical Industry Embraces NIR Technology (PDF)
September 1st 2003Near-infrared spectroscopy moves into warehouses to check incoming drug substances, excipients, and packaging materials, and onto the production floor to monitor characteristics such as blend uniformity, moisture content, and dissolution rate.
