The GC-MS is an extremely useful instrument in determining the identity of a chemical substance. The GC-MS works just like the GC, but the compounds are detected in a different manner. In this instrument, compounds are separated in the GC and then pass into the mass spectrometer, where their molecular mass is determined.
“Ahhhh, Strontium!”Pyrotechnics expert John Conking ‘65, an adjunct professor of chemistry, offered a talk on the Chemistry of Fireworks Saturday afternoon.
