Abstract: A mass spectrometry device and process may include the use of helium as a nebulizing gas to provide increased signal strength in mass spectrum results. This may be implemented in, for example, ESI-based and/or DESI-based systems and/or processes. The process may be implemented utilizing a unique ionization source and, optionally, other unique components. One or more process parameters may be adjusted to provide increased signal intensity in mass spectrum results.
