MAc (Mass Acquisition) is a software package designed for half-automated hardware control, data acquisition and online data analysis for MR-TOF-MS. It offers multi-dimensional automatic hardware parameter optimization e.g. electrode voltage optimization regarding transport efficiency or mass resolving power. Mass resolving powers in excess of 400.000 have been reached. MAc provides support for multiple data acquisition hardware (TDCs and ADCs), online filter features (peak detection, data smoothing etc.) and long-term measurements (days). Automated methods for peak detection and chemical compound identification are provided. Furthermore methods have been developed to visualize long-term signal stability and to correct flight time deviations due to electric field drifts by time-resolved calibration. Applications of MAc’s main features for on- and offline data analysis will be presented.
