Abstract

Balancing the contradiction between portability and analytical performances of a miniaturized mass spectrometer is vital to extend its on-site applications. In this study, triboelectric nanogenerator (TENG)-driven ion sources were coupled with our home-built Mini 2000 system and applied to the analyses of different samples. Compared with the conventional direct current (DC) nanoelectrospray ionization (nanoESI) source, the ion intensity of the TENG-nanoESI miniature mass spectrometer was improved by ∼3 times. Moreover, maybe due to the different pathways of ion formation in comparison with DC electrospray, TENG electrospray is shown to reduce the salt suppression effect during ionization. With these figures of merit, the direct detection of reserpine in saliva was demonstrated using the TENG-Mini 2000 system.
