Tandem mass spectrometry is used to obtain DNA fingerprints as it is used for sequencing of both DNA and RNA.
It involves multiple fragmentation.
In this mass spectrometry, the substrate is first converted to ions and then the ions are separated based on mass to charge ratio. Now these ions separated are further processed for fragmentation producing daughter or product ions. These are again separated and analyzed based on mass to charge ratio.
The barium oxide chemical formula is BaO. The molar mass is 153.33 g/mol. The molecule is formed by one barium cation Ba2+ and one oxide anion O2-. Both ions are bound by one ionic bond.
