Claim 0:
1. A mass spectrometer including an ion source using an atmospheric pressure ionization method for ionizing a component contained in a liquid sample, a mass separator configured to separate ions derived from the sample component in accordance with a mass-to-charge ratio and a detector configured to detect separated ions, the mass spectrometer further comprising:
a parameter optimization unit configured to optimize values for device parameters including a plurality of parameters that affects ionization efficiency in the ion source using a Bayesian optimization method, based on a result acquired by making measurements while changing the values of the device parameters;
a display processor configured to display a sensitivity model which is a posterior distribution indicating a relationship between a plurality of parameters in all or some of the device parameters and signal strength estimated during the optimization of the device parameters by the parameter optimization unit, expressing as a graph like a heat map or an array of a plurality of the graphs on a display, and to sequentially update the sensitivity model; and
a file creation unit configured to allow a user to designate a position on the graph displayed by the display processor and to create a method file containing a measurement condition used for sample measurement, based on a combination of values of parameters corresponding to the designated position.
