Anorexia is a very common manifestation of disease. Cats that are eating ravenously present less of a diagnostic dilemma, as there is a shorter list of illnesses that result in increased appetite (diabetes, hyperthyroidism, pancreatic insufficiency and a few others).
The fragments that survive the journey through the analyzer shoot into the electron multiplier-the detector of the GCMS. The electron multiplier detects every ion of the selected mass that passes through the quadrupole analyzer. Electron multipliers use a process known as secondary electron emission. When the ions hit a surface, it causes the electrons in the outermost area of the atom to be released, which are known as secondary electrons.
The battery terminals are represented as electron-source and electron-sink in the user interface of the models. The function of this variable is to stop the model once a certain number of electrons reach the battery positive, and a monitor displays the time taken to fill the electron-sink.
