Figure 3: IMS Predominant Ionization (positive polarization)
The above figure exemplarily shows typical IMS spectra without analyte and with
analyte. The RIP is formed as a sharp signal proving the cleanliness of the system
and at a specific position that is used as internal standard. The spectrum containing
analytes shows a decreased RIP, while new (analyte) peaks are correspondingly
formed. The drift time is specific to an ion; therefore analyte identification is possible.
The peak height and area correlate to the analyte concentration, so that a
quantification is also possible.
