Abstract
A system comprises an electrostatic trapping mass analyzer and an information processor configured to receive a transient signal from the electrostatic trapping mass analyzer at a maximum resolution, the information processor comprising instructions operable to: partition the transient signal into segments and, while a quality metric is either less than a pre-determined minimum threshold or greater than a pre-determined maximum threshold value, to perform the steps of: (i) defining a test transient as being equal to either a first one of the segments or a previously defined transient with an appended signal segment; (ii) generating a spectrum of component frequencies by calculating a mathematical transform of the test transient; and (iii) determining the quality metric from the spectrum of component frequencies; and set an instrumental resolution to be employed for subsequent mass spectral data acquisitions in accordance with a length of the most-recently-defined test transient.
