This new column looks at the current importance of electrospray ionization and emerging approaches for samples that require ionization by other means, including a new technology, multimode ionization.
Tracking Degradability of PBSu with Size-Exclusion Chromatography
February 21st 2025The biodegradability of poly(butylene succinate) (PBSu) in marine environments is under scrutiny. As it is well known that the biodegradability of biodegradable polymers depends on their molecular weight, researchers explored the effect of that factor of PBSu on its biodegradability through biochemical oxygen demand (BOD) testing in seawater, with samples of differing molecular weight prepared with size-exclusion chromatography (SEC).
The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
