Mass spectrometry is an analytical technique that uses an instrument called a mass spectrometer to measure the mass-to-charge ratios of molecular ions. Molecules fragment within the mass spectrometer to produce a mass spectrum, which can be interpreted to determine the identity of the molecules in ...

to interact with data within the database itself. Tandem mass spectral databases are acquired by the analysis of reference standards. Since a fragmentation spectrum can look different depending on the excitation process (e.g., resonant vs. non-resonant) as well as the collision energy applied to...
In subject area:Chemistry A Tandem Mass Spectrum is a type of mass spectrum that contains predominantly b- and y-ions, which are generated from the peptide sequence as prefixes and suffixes, respectively. It is used to identify peptide sequences based on the observed m/z values of these ions...
