Selective reaction monitoring
WebThis technique is known as selected reaction monitoring (SRM), and is frequently used for quantification. Fragmentation is usually achieved in a collision cell pressurized with an inert gas such as argon. Collision of ions with atoms in the cell produces fragments by a process known as collision induced dissociation (CID). WebSelected reaction monitoring (SRM) is a highly sensitive and selective method for the targeted quantitation of peptides and, by inference, the corresponding proteins in …
