Interpretation Introduction
Interpretation:
The difference between the spectra of EI, field ionization and the CI sources is to be stated.
Concept introduction:
Ionization refers to the process in which an atom or a molecule obtains a positive or a negative charge by losing or gaining an electron. This results in the synthesis of an ion. There are a variety of ionization methods. These include chemical ionization, electron impact, electrospray ionization, field ionization etc.

- Technetium is the first element in the periodic chart that does not have any stable isotopes. Technetium-99m is an especially interesting and valuable isotope as it emits a gamma ray with a half life ideally suited for medical tests. It would seem that the decay of technetium should fit the treatment above with the result In(c/c) = -kt. The table below includes data from the two sites: http://dailymed.nlm.nih.gov/dailymed/druginfo.cfm?id=7130 http://wiki.medpedia.com/Clinical: Neutrospec_(Technetium_(99m Tc)_fanolesomab). a. b. C. Graph the fraction (c/c.) on the vertical axis versus the time on the horizontal axis. Also graph In(c/c.) on the vertical axis versus time on the horizontal axis. When half of the original amount of starting material has hours fraction remaining disappeared, c/c = ½ and the equation In(c/c.) = -kt becomes In(0.5) = -kt1/2 where t₁₂ is the half life (the time for half of the material to decay away).
