Introduction to Mass Spectrometry (MS) A mass spectrometer produces a spectrum of masses based on the structure of a mol

Introduction to Mass Spectrometry (MS) A mass spectrometer produces a spectrum of masses based on the structure of a mol

Introduction to Mass Spectrometry (MS) A mass spectrometer produces a spectrum of masses based on the structure of a molecule. The x-axis of a mass spectrum represents the masses of ions produced (m/z) The y-axis represents the relative abundance of each ion produced

The Atom

The Atom

The Atom. How big is an Atom?. The average size atom (Al) is about 0.00000003 cm. It would take a stack of 50,000 aluminum atoms to equal the thickness of a sheet of aluminum foil. That’s Small!!!!. What’s Inside an Atom?.

History of The Atom

History of The Atom

History of The Atom. Democritus – 400B.C. He believed matter was made up of empty space and tiny particles he called “ atomos ” Said different things were made with different types of atoms. Aristotle – 335 B.C. Matter was continuous – “what you see is what you get”
