摘要 |
A method for matching a precursor ion with one or more related product ions includes providing input data sets obtained from sample injections, each of the data sets including a precursor ion and one or more product ions, normalizing the input data sets in accordance with a single retention time for the precursor ion, determining which product ions are within a predetermined retention time window with respect to the single retention time, and, if a product ion is within the predetermined retention time window for a specified number of the input data sets, determining that the product ion is related to the precursor having the single retention time. An apparatus for analyzing a sample includes a chromatography module, a mass-spectrometry module in communication with the chromatography module, and a control unit in communication with the chromatography module and the mass-spectrometry module. |
