Mass Spectrometry

Explore the fascinating world of mass spectrometry in this presentation by Matthew Cash. Delve into its origins, tracing back to Arthur Dempster, and discover the core principles of how this analytical technique works. By shooting electrons at molecules, mass spectrometry breaks them apart to analyze and identify various compounds, including larger molecules. Visual aids such as graphs and videos enhance understanding, paving the way for discussions and questions about this crucial tool used in chemistry and biochemistry.
