    摘要: A method of searching for potentially unknown metabolites of pharmaceutical compounds is disclosed. The accurate mass of a pharmaceutical compound will generally be known and can be rendered in the form of an integer nominal mass or mass to charge ratio component and a decimal mass or mass to charge ratio component. Possible metabolites are searched for on the basis of having a decimal mass or mass to charge ratio component which is substantially very similar to the decimal mass or mass to charge ratio of the parent pharmaceutical compound.

    摘要: A mass spectrometer comprising a collision, fragmentation or reaction cell (4) is disclosed. The collision, fragmentation or reaction cell (4) is repeatedly switched back and forth between a high fragmentation mode of operation and a low fragmentation mode of operation. Mass spectral data sets are obtained in both modes of operation. A decimal mass filter is applied to one or both sets of data. In particular, fragment ions or metabolites related to a parent or precursor ion of interest are identified on the basis of having a decimal mass which is similar to that of the parent or precursor ion of interest.
