AbstractIn this thesis a new design for electrospray ionization ion mobility spectrometry ESI IMS was developed This design has two important differences in comparison to thepresent ESI IMS systems First a few centimeters of the cell comprising the electrosprayneedle was located outside of the oven used for heating the IMS cell This modificationprevents prespray solvent evaporation problems such as needle clogging and disturbanceof the electrospray process Second in addition to the drift gas a counterflow of a heatedgas desolvation gas was used between the counter electrode and the ion gate to speed upthe desolvation process This modification increased the solvent evaporation resulted indecreasing the drift time increasing the peak intensity and increasing the resolving power RP or enhancing the resolution for separation of two adjacent ion peaks Additionally the ion mobility spectra of different compounds including ethion malathion metalaxyl fenamifos methylamine triethylamine tributhylamine codeine and morphine wereobtained to confirm enhancing of the resolving power of the ion peaks by using thedesolvation gas Furthermore the method has also been applied to obtain the figures ofmerit for ethion as a test compound The linear dynamic range for ethion was in the range50 to 1000 g L 1 with a limit of quantification of the 50 g L 1 In addition the ion mobility spectrometer with corona discharge as an ionizationsource CD IMS was used for qualitative and quantitative analysis of narcotics morphine and noscapine in mixture solutions antibiotic furazolidone chloramphenicol and enrofloxacin residues in chicken meat furfurals 2 furfural and 5 methyl 2 furfural in mixture solutions and ammonia nitrogen in water samples Thefigures of merit obtained demonstrate the capability of CD IMS for analysis of thesecompounds
