Previously, vacuum matrix-assisted ionization (vMAI) was employed with matrix/analyte sample introduction into the vacuum of a mass spectrometer on a probe sample introduction device. Low attomole detection was achieved, while no carryover was observ

Sublimation has been known at least since the middle ages. This process is frequently taught in schools through the use of phase diagrams. Astonishingly, such a well-known process appears to still harbor secrets. Under conditions in which compound su

Ionization processes have been discovered by which small and large as well as volatile and nonvolatile compounds are converted to gas-phase ions when associated with a matrix and exposed to sub-atmospheric pressure. Here, we discuss experiments furth

An unexpected ionization process was recently discovered for use in mass spectrometry in which no added energy is required to convert condensed-phase molecules to ESI-like gas-phase ions. This process offers the opportunity to greatly simplify ioniza

Atmospheric solids analysis probe (ASAP) mass spectrometry is an effective means for rapidly analyzing liquids, solids, or material surfaces by direct introduction into an atmospheric pressure (AP) ionization source. A sample is typically placed on t

Vacuum matrix-assisted ionization (vMAI) uses select matrix compounds which when exposed to the vacuum of a mass spectrometer produce gas-phase ions from associated volatile or nonvolatile analyte without external energy input. Here, a vMAI source wa
