However, every single method has its limitation in terms of polarity and molecular weight of analyte molecules. After the miniaturization of every possible component of the different ion sources, we finally were able to embed two emitters and an ion transfer tubing into a small, hand-held device. The pen-like interface is connected to the mass spectrometer and a separate control unit via a bundle of flexible tubing and cables. The novel device allows the user to ionize an extended range of chemicals by simple switching between DESI, voltage-free EASI, or LTP ionization as well as to freely move the interface over a surface of interest. A mini camera, which is mounted on the tip of the pen, magnifies the desorption area and enables a simple positioning of the pen. The interface was successfully tested using different types of chemicals, pharmaceuticals, and real life samples. Moreover, the combination of optical data from the camera module and chemical data obtained by mass analysis facilitates a novel type of imaging mass spectrometry, which we name “interactive mass spectrometry imaging (IMSI)”."}],"publication_status":"published","publication":"Analytical Chemistry","extern":"1","type":"journal_article","date_updated":"2023-05-15T08:01:20Z","volume":92,"publication_identifier":{"issn":["0003-2700","1520-6882"]},"external_id":{"pmid":["33063994"]},"status":"public","page":"14314-14318","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","month":"10","date_created":"2023-05-10T14:50:19Z","citation":{"ama":"Meisenbichler C, Kluibenschedl F, Müller T.
