Plasma-based ambient desorption/ionization sources are versatile in that they enable direct ionization of gaseous samples as well as desorption/ionization of analytes from liquid and solid samples. However, ionization matrix effects, caused by competitive ionization processes, can worsen sensitivity or even inhibit detection all together.

Ambient desorption/ionization (ADI) sources coupled to mass spectrometry (MS) offer outstanding analytical features: direct analysis of real samples without sample pretreatment, combined with the selectivity and sensitivity of MS. Since ADI sources typically work in the open atmosphere, ambient conditions can affect the desorption and ionization ...

The Luminescence of Water Excited by Ambient Ionizing Radiation
Radiation Research, 1971A nondecaying weak luminescence of intensity 1.5 ± 0.1 photons ${\rm sec}^{-1}\ {\rm ml}^{-1}$ has been observed from purified water exposed to ambient ionizing radiation. The structured emission spectrum and the observed quenching by dissolved oxygen, indicated that a substantial portion of the luminescence was non-Cerenkov emisson.

Inlet and Vacuum Ionization from Ambient Conditions
2014The discovery that laser ablation of a common MALDI matrix at atmospheric pressure without use of a voltage produced ions with nearly identical charge states to ESI led to a series of new ionization methods that we have given the general term inlet and vacuum ionization.

The Journal of Physical Chemistry A
Microdroplet chemistry has been utilized in different fields due to a plethora of unique properties such as the existence of a high electric field up to 109 V/m at the surface of the microdroplets or between two oppositely charged microdroplets. Such a high field endows microdroplets with the ability of ionizing ambient air.
