Mass spectrometer resolution
Resolution required to separate two neighbouring X and Y elements.
uma
Unit of atomic mass. Experimentally obtained value not belonging to the International System (SI). Equivalent to 1.6605 × 10 –27 kg or 1/12 of the mass of a 12 C atom.
Mass spectrometer sensitivity
An analyzer's ability to measure the largest electrical signal for a given quantity of gas. For mass spectrometers, this can be expressed in Amperes (measurement of ions emitted by the analyzer source) per unit of pressure (Pascal, Torr...).
