The goal of this study was to explore the use of LC-captive spray ionization (CSI)-mass spectrometry for detection, characterization and quantification of drugs and metabolites. CSI allows the use of conventional HPLC or uHPLC columns and flow rates of 0.35-0.6 mL/min (before post-column flow splitting) and can be considered as a technique.

Untargeted mass spectrometry is employed to detect small molecules in complex biospecimens, generating data that are difficult to interpret. We developed Qemistree, a data exploration strategy based on the hierarchical organization of molecular fingerprints predicted from fragmentation spectra.


Applications of Mass Spectrometry

Cold spray ionization mass spectrometry (CSI-MS) is a variant of ESI-MS that promotes ionization by increasing the polarizability of the compound at low temperature [17]. This native-MS technique allows the facile and precise characterization of weak noncovalent interactions in solutions compared to the conventional ESI method [18].

Cold-spray ionization (CSI) is designed for the MS detection of labile organic species. It is used to analyze the structures of biomolecular complexes and labile organic species in solution.


Coldspray ionization (CSI) mass spectrometry (MS) has been developed and applied to characterize labile organometallic compounds. While conventional ESI is not applicable to those compounds because of their instability to heat and/or air, CSI affords multiply charged molecular ions with many solvents molecules attached. Here we describe the CSI method and its application to several labile.
