Two common methods for \u0394        \u0394 determining the ratio of m to     m (m\/    m) are: - m is the mass of a component comprising the first peak of a doublet, and  \u0394m is the difference in the mass of the two peaks. The doublet shall be separated by a valley, the value of which shall not exceed 10 % of the value of the highest peak (m\/ \u0394m is constant (sector type)). \u0394 - m is the mass of a sample component within a peak and         m is the full width at half maximum (FWHM) of the peak ( \u0394m is \u0394 constant, (quadrupole type)). Thus m\/      m decreases as mass decreases. With this type of instrument unit resolution, one can separate each mass from the  next integer mass, i.e. one can distinguish mass 50 from mass 51, and distinguish mass 1000 from mass 1001 "}],"skos:broader":["https:\/\/digilab.ptb.de\/oiml-g-18\/vocab\/skos\/2"]}
