    Abstract: One aspect of the disclosure provides a method of mass spectrometric analysis that includes producing either glow discharge within a noble gas between 3-100 mBar pressure, sampling and conditioning glow discharge products within a gas flow through a conductive channel, removing charged particles while transferring excited Ridberg atoms, and mixing conditioned discharge products with analyte flow within an enclosed chamber at elevated temperatures above 150° Celsius for producing a Penning reaction between analyte molecules and Ridberg atoms. The method further includes sampling, by a gas flow, said analyte ions for mass spectrometric analysis, and at least one of the following steps: (i) removing charge within said conditioning channel; (ii) coaxially mixing of analyte flow with the flow of conditioned plasma; and (iii) cooling of the mixed flow within a sonic or supersonic jet for reducing the region of Penning ionization to cold jet.

    Abstract: The metastable atom bombardment source provides a charged particle free beam of metastable species that can be used to bombard and ionize organic and inorganic substances in a gas phase. The metastable atoms are produced by inducing a discharge in a gas (rare gases or small molecules). The discharge is curved between the cathode and anode, with the cathode located in a medium pressure zone and the anode located off-axis in a low pressure zone. A nozzle located between the cathode and the anode provides a collimated beam of metastable atoms of low kinetic energy that is directed at an ion volume containing the substances to be analyzed. By selecting the energy of the metastable state, selective fragmentation of molecules, particularly large molecular weight molecules, can be carried out.
