Abstract:
Under the control of an analysis control unit ( 5 ), a mass spectrometer unit ( 2 ) performs a product-ion scan measurement for a target component in a target sample within a time range where the component is introduced. It also performs a scan measurement over an m/z range including the m/z of an ion originating from a standard component within the same segment of time. A mass correction information calculator ( 42 ) calculates mass correction information from measured and theoretical values of the m/z of the ion originating from the standard component observed on an MS spectrum obtained by the scan measurement. Using the mass correction information, a mass corrector ( 43 ) corrects the m/z of each ion peak originating from the target component observed on an MS/MS spectrum obtained by the product-ion scan measurement performed within the same cycle as the scan measurement concerned. It is possible to consider that the MS measurement and the MS/MS measurement within the same cycle have been almost simultaneously carried out. Accordingly, a mass correction which is almost equivalent to an internal standard method can be achieved.

Claim (Index 2):
The tandem mass spectrometer according to  claim 1 , wherein:\n the correction processor corrects the mass-to-charge ratio of the product ion originating from the component in the target sample, using the mass-to-charge ratio of the ion originating from the standard component obtained in the scan measurement carried out within the same cycle as the product-ion scan measurement concerned.
