OAD-TOF System

The world’s first quadrupole time-of-flight mass spectrometer system equipped with ion dissociation technology

The OAD-TOF system, a quadrupole time-of-flight mass spectrometer, is the first in the world to provide detailed structural analyses of lipids and other natural compounds. Oxygen attachment dissociation (OAD), an ion dissociation technology developed by Shimadzu, enables estimation of the position of double bonds between carbon atoms, a conventionally difficult task. In OAD, atomic oxygen is made to react with the ionized sample, and the double bonds between carbon atoms are selectively broken (dissociated). Information on the position of the double bonds between carbon atoms is then obtained from the ion fragments generated by the dissociation. A quadrupole time-of-flight mass spectrometer (Q-TOF MS) measures the size and amount of samples separated at the atomic and molecular levels, thereby obtaining precise information on compounds. In combination, these techniques elucidate the structure of all types of compounds including lipids and other biological compounds.
