Classification: CPC G  H | IPC G  H

Claim 3:
4. The mass spectrum processing apparatus according to claim 2, wherein
k is equal to or greater than 3,
the number of top peaks, k, are formed from a highest peak and k−1 upper peaks,
wherein, when identifying the representative value array formed from a plurality of representative values as a characteristic amount of the mass spectrum, the at least one processor of the graph generation unit is further configured to:
calculate, as the representative value array, a ratio array formed from a ratio of intensities of the k−1 upper peaks to an intensity of the highest peak; and

wherein, when plotting the plurality of graphs, the at least one processor of the graph generation unit is configured to:
generate k−1 graphs by plotting a plurality of ratio arrays obtained from the plurality of mass spectra in a coordinate system having a retention time axis and a ratio axis.
