FOURIER TRANSFORM MASS SPECTROMETER AND METHOD FOR GENERATING A MASS SPECTRUM THEREFROM |
摘要 |
A method of generating a mass spectrum from an FTMS is disclosed. A first quantity of ions from a source, having a first m/z range, is captured and detected in the FTMS measurement cell to produce a first output. A second quantity of ions, having a second m/z range which at least partially does not overlap with the first m/z range, is then captured and detected so as to produce a second output. The two outputs are then combined using a processor so as to "stitch" together the outputs, which may be FTMS transients or may first be Fourier Transformed into the frequency mass domain, into a composite output from which a composite mass spectrum covering the full range of m/z ratios included by the first and second ranges can be produced. |
