摘要： Systems and methods are disclosed for detecting compounds in a sample using a tandem mass spectrometer. A sample comprising a plurality of detectable compounds that have been separated in time over a time interval is introduced into a tandem mass spectrometer. A sample product ion spectra is obtained. The presence of one or more known compounds of interest in the sample product ion spectra is determined. A compound is identified as present in the sample if the score associated with said compound meets a threshold value set as indicative of the likely presence of the compound in the sample.

摘要： Systems and methods are provided for analyzing a sample using overlapping measured mass selection window widths. A mass range of a sample is divided into two or more target mass selection window widths using a processor. The two or more target widths can have the same width or variable widths. A tandem mass spectrometer is instructed to perform two or more fragmentation scans across the mass range using the processor. Each fragmentation scan of the two or more fragmentation scans includes a measured mass selection window width. The two or more measured widths of the two or more fragmentation scans can have the same width or variable widths. At least two of the two or more measured mass selection window widths overlap. The overlap in measured mass selection window widths corresponds to at least one target mass selection window width.

摘要： Systems and methods are used to rapidly screening samples. A fast sample introduction device that is non-chromatographic is instructed to supply each sample of a plurality samples to a tandem mass spectrometer using a processor. The fast sample introduction device can include a flow injection analysis device, an ion mobility analysis device, or a rapid sample cleanup device. The tandem mass spectrometer is instructed to perform fragmentation scans at two or more mass selection windows across a mass range of each sample of the plurality of samples using the processor. The two or more mass selection windows across the mass range can have fixed or variable window widths. The tandem mass spectrometer can be instructed to obtain a mass spectrum of the mass range before instructing the tandem mass spectrometer to perform the fragmentation scans.

摘要： A precursor ion spectrum and one or more product ion spectra are received from a tandem mass spectrometer that analyzes a compound. For a selected precursor ion peak in the precursor ion spectrum, mass differences are calculated between other peaks and one or more limitations on the number of elements in the selected precursor ion are generated. For a precursor ion peak, a product ion spectrum is located from the one or more product ion spectra. For a selected product ion peak in the product ion spectrum, mass differences between other peaks are calculated and one or more limitations on the number of elements in the selected product ion are generated. Limitations on the number of elements from the precursor ion and the product ions are combined. One or more elemental compositions are generated from a mass of the selected precursor ion peak and the combined limitations.

摘要： Systems and methods are used to analyze a sample using variable mass selection window widths. A tandem mass spectrometer is instructed to perform at least two fragmentation scans of a sample with different mass selection window widths using a processor. The tandem mass spectrometer includes a mass analyzer that allows variable mass selection window widths. The selection of the different mass selection window widths can be based on one or more properties of sample compounds. The properties may include a sample compound molecular weight distribution that is calculated from a molecular weight distribution of expected compounds or is determined from a list of molecular weights for one or more known compounds. The tandem mass spectrometer can also be instructed to perform an analysis of the sample before instructing the tandem mass spectrometer to perform the at least two fragmentation scans of the sample.

摘要： Apparatus is provided and an IDA method is modified to detect and separately dissociate alkali-metal adducts of a compound. An ion source device ionizes one or more compounds of a sample, producing an ion beam. A mass filter selects a mass range of precursor ions from the ion beam, a mass analyzer measures intensities and m/z values of the precursor ions, and one or more of the precursor ions are selected for a peak list. For each pair of precursor ions of the peak list, if an m/z difference between the pair corresponds to an m/z difference between an alkali metal ion and another alkali metal ion or a proton, an ExD device is used to dissociate one precursor ion or both precursor ions of the pair using the processor. A CID device is used to dissociate all other precursor ions of the peak list.
