He relates a theory that hundreds of bodies larger than Ceres, perhaps as large as Mars, may have existed in the early asteroid belt, without pointing out that presumably all of these bodies were ejected, intact, from the solar system (they're too big to have been collisionally fragmented into smaller pieces).
In addition the design of the electrospray ion source can permit a molecular ion to undergo a process known as collisionally induced decomposition.
The optimization included collisionally activated dissociation MS/MS, which was performed in the second quadrupole with nitrogen at 0.
