University of Arizona Core Facilities Highlight Mass Spectrometry Research Mass spectrometry has become an essential tool for researchers exploring the molecular intricacies of diverse materials, from biological samples to extraterrestrial substances. The University of Arizona’s Analytical and Biological Mass Spectrometry Core Facility plays a pivotal role in this scientific endeavor, offering advanced instrumentation and expertise to scientists across disciplines. The facility, directed by Krishna Parsawar, is dedicated to analyzing complex samples to determine their molecular composition. This process involves measuring the mass-to-charge ratio of ionized molecules, enabling precise identification of structures, molecular weights, and impurities. Such accuracy is critical for understanding how chemical compounds behave, ensuring their safety, and evaluating their effectiveness. Parsawar emphasized the versatility of mass spectrometry, noting that it is indispensable for researchers tackling a wide range of questions. For example, pharmaceutical chemists use the technology to study drug metabolism and efficacy, while forensic scientists analyze trace evidence from crime scenes. Planetary scientists have even applied it to lunar dust samples, and historians employ it to examine ancient artifacts. The facility’s state-of-the-art equipment and team of specialists support collaborations with researchers from the university’s Cancer Center and beyond. One notable project involved analyzing mummy samples, where scientists examined dyes used in ancient textiles and hair composition from 5,000-year-old remains. These studies highlight the technology’s ability to uncover insights into historical and scientific mysteries.#university_of_arizona #krishna_parsawar #bio5_institute #thomas_keating_building
