The Biemann Medal is awarded to an individual early in his or her career to recognize significant achievement in basic or applied mass spectrometry. Trimpin’s award is for unusual observation of highly charged protein ions in an atmospheric pressure matrix-assisted laser desorption-ionization (MALDI) experiment that led to her discovery that ionization occurs simply by passing compounds through the inlet of a mass spectrometer. Trimpin demonstrated that her simple approach achieves sensitivity comparable with, and frequently better than, electrospray or MALDI.
Through fundamental studies, Trimpin discovered solid matrices that produce highly charged ions upon laser ablation using MALDI ion sources. She also discovered matrix compounds that spontaneously produce multiply charged ions when exposed to vacuum (termed matrix-assisted ionization). She has now discovered more than forty matrices that spontaneously produce analyte ions. Her work has been recognized by numerous awards and has led to commercialization.
Researchers Develop Adaptive Gap-Tunable SERS Device
April 24th 2024In a new study, researchers from Ulsan National Institute of Science and Technology and Pohang University of Science and Technology presented a new surface-enhanced Raman spectroscopy (SERS) device, improving gap plasmon resonance.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
