Sublimation Driven Ionization for Use in Mass Spectrometry: Mechanistic Implications

Autor: Khoa Hoang, Milan Pophristic, I-Chung Lu, Charles N. McEwen, Sarah Trimpin, Ellen D. Inutan, Abigail Moreno-Pedraza

Publikováno v: Journal of the American Society for Mass Spectrometry. 32(1)

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

Publikováno v: Journal of the American Society for Mass Spectrometry. 32(1)

Ion mobility spectrometry (IMS) mass spectrometry (MS) centers on the ability to separate gaseous structures by size, charge, shape, and followed by mass-to-charge (m/z). For oligomeric structures,...

An overview of biological applications and fundamentals of new inlet and vacuum ionization technologies

Publikováno v: Rapid communications in mass spectrometry : RCMREFERENCES. 35

Rationale The developments of new ionization technologies based on processes previously unknown to mass spectrometry (MS) have gained significant momentum. Herein we address the importance of understanding these unique ionization processes, demonstra

Spontaneous Charge Separation and Sublimation Processes are Ubiquitous in Nature and in Ionization Processes in Mass Spectrometry

Autor: Charles N. McEwen, Nicholas D. Chubatyi, Milan Pophristic, Stephan Rauschenbach, Beixi Wang, Ellen D. Inutan, Khoa Hoang, I-Chung Lu, Sarah Trimpin, Alexander Sidorenko, Wen-Jing Zhang

Publikováno v: Journal of the American Society for Mass Spectrometry. 29:304-315

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

Publikováno v: Analytical Methods. 9:4971-4978

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

Publikováno v: Rapid communications in mass spectrometry : RCMREFERENCES. 34

RATIONALE New ionization processes have been developed for biological mass spectrometry (MS) in which the matrix lifts the nonvolatile analyte into the gas phase as ions without any additional energy input. We rationalized that additional fundamental
