Gas Chromatography-Mass Spectroscopy

Mass Spectroscopy As the individual compounds elute from the GC column, they enter the electron ionization (mass spec) detector. There, they are bombarded with a stream of electrons causing them to break apart into fragments. These fragments can be large or small pieces of the original molecules.

Specimen Section 2

A radioactive isotope X, which is used in hospitals, has a half-life of 6.0 hours. It decays to form an isotope Y of a different element which is not radioactive. A pure sample of X is produced in a nuclear reactor. Twelve hours later, when the sample arrives at a hospital, the number of atoms of X in the sample is 1.6 × 10
