Here, paper spray ionization mass spectrometry (PSI-MS), one of the ambient mass spectrometry technologies, is developed to characterize the content of drugs in dissolution media. The porous structure of paper can effectively retain salts from entering mass spectrometer. This makes the measurement of...
Paper Spray ionizationtandem mass spectrometrylabeled internal standardsA fast methodology for the assay of parabens in drug and cosmetic preparations has been presented. The procedure developed is based on paper spray tandem mass spectrometry and isotope dilution approach. For each investigated paraben, ...
Paper spray ionization (PSI) mass spectrometry (MS) is an emerging tool for ambient reaction monitoring via microdroplet reaction acceleration. PSI-MS was used to accelerate and monitor the time course of the reaction of dansyl chloride with aniline, in acetonitrile, to produce dansyl aniline. Thr...
The present study reports a paper spray (PS)method which has characteristics of both ESI and the ambient ionization methods and is useful for fast,qualitative,and quantitative analysis of complex mixtures.Analyte transport is achieved by wicking in a porous material with a macro- scopically sharp ...
This result of internal energy distributions suggests these two ionization methods might follow the same mechanism. In summary, paper spray mass spectrometry (PSMS) has desirable features for clinical applications, including neonatal screening, therapeutic drug monitoring, and, possibly in the future, ...
