The mass spectrometry facility at the JHU Chemistry Department contains six instruments equipped with a variety of different ionization techniques. Each is based on a different combination of mass analyzer design and ionization source and therefore has different analytical capabilities. Together, they form a suite of instruments that provides a comprehensive range of analytical organic...
If two atoms are isotopes of the same element, the atom of higher mass number has the higher priority. For example, in 2-butene, the carbon atom of each methyl group receives first priority over the hydrogen atom connected to the same carbon atom.
