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.
electron volt. Standard unit of energy in particle physics. One electron volt is the energy gained by an electron that is being accelerated by an electric potential difference (electric voltage) of 1 volt. One electron volt, in short: 1 eV is equivalent to 1.602176Â·10-19 Joule (the Joule being the energy unit of the SI system of units).
