Retaining Polar Compounds

A new separation platform based on chromatographic techniques was used to characterize algae hydrocolloids.

In episode #37 of Analytically Speaking, podcast host Dr. Jerry Workman speaks with Dr. Austin Daniels, application scientist for Yokogawa Fluid Imaging Technologies, about flow imaging microscopy (FIM), a new technology for sub-visible particle characterization in biologics.

A joint study between the Nursing School of North Henan Medical University (Xinxaing, China) and The First Affiliated Hospital of Harbin Medical University (Harbin, China) used gas chromatography–mass spectrometry (GC-MS) for an observational study collecting and classifying surgical smoke generated during laparoscopic surgery to evaluate the carcinogenic risks to healthcare workers.

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.
