Publication number: 20240063006Abstract: Methods for acquiring mass spectral data comprise determining first and second sets of m/z sub-ranges comprising respective first and second m/z sub-ranges. A sample is mass filtered to isolate ions in the first and second sets of m/z sub-ranges using respective mass filters. Mass analysis is performed to obtain first and second partial mass spectral data sets, the first and second mass filters having first and second response profiles having respective relatively high transmission regions and one or more relatively low transmission regions. The first and second sets of m/z sub-ranges are determined such that relatively high transmission regions of the first response profile and the second response profile at least partially overlap.Type: ApplicationFiled: August 11, 2023Publication date: February 22, 2024Applicant: Thermo Fisher Scientific (Bremen) GmbHInventors: Christian THÖING, Alexander MAKAROV, Denis CHERNYSHEV

Publication number: 20240055245Abstract: Methods for acquiring mass spectral data of a sample across at least a portion of an m/z range comprise receiving mass spectral data across the m/z range and partitioning the m/z range into one or more sets of m/z sub-ranges, each set comprising one or more m/z sub-ranges, by dividing the m/z range into a plurality of m/z bins, determining an indication of ion abundance for each m/z bin, based on the mass spectral data, and forming an m/z sub-range of the one or more sets of m/z sub-ranges by assigning m/z bins having ion abundances that correspond to at least a threshold degree to the formed m/z sub-range. A mass analysis is performed on the sample for each set of m/z sub-ranges, thereby acquiring one or more partial mass spectral data sets.Type: ApplicationFiled: August 10, 2023Publication date: February 15, 2024Applicant: Thermo Fisher Scientific (Bremen) GmbHInventors: Christian THÖING, Alexander MAKAROV, Denis CHERNYSHEV
