A mobile multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) combines the advantages of high mass resolving power and high mass accuracy with the possibility of in-situ mass measurement applications in the field. For example, it is an excellent tool for real-time tissue recognition in electrosurgery and identification of mycotoxins. Such a mobile MR-TOF-MS has been developed and a mass resolving power in excess of 100.000 has been demonstrated.
To enable the coupling of various types of ion sources to the mass spectrometer, an atmospheric pressure interface (API) has been designed and commissioned. The API is connected to an RFQ ion trap system consisting of a mass filter, ion cooler and ion trap. The ion trap system ensures the highly efficient transport of the ions from the ion source to the mass analyzer and provides cooled ions for the bunched extraction into the mass analyzer. A characterization and first measurement results of the MR-TOF-MS utilizing the new ion trap system in combination with the API will be presented.
