To do so, it imparts an electrical charge to molecules and converts the resultant flux of electrically charged ions into a proportional electrical current that a data system then reads.

The dalton (symbol: Da) is the standard unit that is used for indicating mass on an atomic or molecular scale (atomic mass). The unified atomic mass unit (symbol: u) is equivalent to the dalton. One dalton is approximately the mass of one a single proton or neutron. The unified atomic mass unit has a value of 1.660538921(73)×10 kg. The amu without the "unified" prefix is an obsolete unit based on oxygen, which was replaced in 1961.

WebSince the mass spectrometer randomly selects peptides for fragmentation, it is still challenging to consistently identify and quantify low-abundance peptides.
