文摘

The parameters influencing the combination of the dielectric barrier electrospray (DB-ES) with an ion trap mass spectrometer are investigated. Two approaches are presented: the application of different polarity cycles in the DB electrospray high voltage signal and the triggering of it to an output signal received by the mass spectrometer. Both approaches are addressed to improve the detection sensitivity over the sensitivity of conventional nano ES.
