Fractionation When Using Direct Insertion Probes

4 Fractionation When Using Direct insertion Probes 

Using RICs, the ions belonging to the same component can readily be identified from their parallel dependence in time (Fig. 5.10). The increase of the signal at m/z 194 in the chromatogram during late scans results from the presence of a minor signal at m/z 194 in the mass spectrum of the target compound. (More examples for the use of RICs are presented in Chap. 14.)
