High-pressure gas phase femtosecond laser ionization mass spectrometry.
We describe a novel ion source for analytical mass spectrometry based on femtosecond laser ionization at pressures at and above atmospheric and characterize its performance when coupled to a tandem quadrupole/time-of-flight mass spectrometer. We assess source saturation limits, ionization and sampling efficiencies, the effective ionization volume, and limits of detection. We demonstrate 100% ef...
متن کاملIsoelectric Focusing, Matrix-assisted Laser Desorption/ionization Time-of- Flight Mass Spectrometry, Electrospray Ionization Mass Spectrometry
LEVEL: INTERMEDIATE D iscovery, development, and commercialization of novel biologics frequently involve collaboration between two or more companies. In the context of these business relationships, transfer of technology from one institution to another is a crucial step that needs to be executed f lawlessly and rapidly. Follow-up activities usually include the development of productive, reliabl...
متن کاملGas chromatography/multiphoton ionization/time-of-flight mass spectrometry using a femtosecond laser.
A laser can be used for the selective excitation and subsequent ionization of a molecule with an absorption band at the laser wavelength. This technique of multiphoton ionization (MPI), when combined with time-of-flight mass spectrometry (TOF-MS), permits the efficient detection of induced ions in mass analysis. This combination of MPI/TOF-MS can be coupled with gas chromatography (GC) to achie...
متن کاملDetection of posaconazole by surface-assisted laser desorption/ionization mass spectrometry with dispersive liquid-liquid microextraction.
A simple, rapid, and sensitive method for the detection of posaconazole using dispersive liquid-liquid microextraction (DLLME) coupled to surface-assisted laser desorption/ionization mass spectrometric detection (SALDI/MS) was developed. After the DLLME, posaconazole was detected using SALDI/MS with colloidal gold and α-cyano-4-hydroxycinnamic acid (CHCA) as the co-matrix. Under optimal extract...
متن کاملBacteriocin detection from whole bacteria by matrix-assisted laser desorption ionization-time of flight mass spectrometry.
Class I bacteriocins (lantibiotics) and class II bacteriocins are antimicrobial peptides secreted by gram-positive bacteria. Using two lantibiotics, lacticin 481 and nisin, and the class II bacteriocin coagulin, we showed that bacteriocins can be detected without any purification from whole producer bacteria grown on plates by matrix-assisted laser desorption ionization-time of flight mass spec...
