Claim Text:
1. A non-thermal plasma jet device as spatial ionization source for ambient mass spectrometry of the type that allows a free adjustment of the geometry of the emerging plasma beam, wherein said device comprises a double dielectric barrier probe of non-thermal plasma or NTP probe, which generates a non-thermal plasma jet; a high voltage and high frequency transformer circuit connected to an external electrode through which it is possible to perform the discharge for gas ionization that producing plasma; wherein said plasma generator circuit is in turn connected to an AC power source; a grounded internal electrode, which allows to perform the discharge for producing plasma; a storage tank for a gas serving as discharge gas; a test sample on which the non-thermal plasma jet is applied; and a ion transfer adapter to direct the ions produced by the device from the vacuum-free sample to a mass analyzer.
