Direct analysis of catalysts immobilised in ionic liquids using electrospray ionisation ion trap mass spectrometry.
Catalysts immobilised in ionic liquids have been analysed using electrospray ionisation ion trap mass spectrometry, which allows identification of the catalyst without contamination from the ionic liquid; additionally, a new ionic liquid containing the Monsanto catalyst as the anionic component, [Rh(CO)2I2]-, has been characterised using the same method.
متن کاملQuantification of Melittin in Iranian Honey Bee (Apis mellifera meda) Venom by Liquid Chromatography-electrospray Ionization-ion Trap Tandem Mass Spectrometry (LC-ESI-IT-MS/MS)
The current research aimed to quantify melittin (MEL) in Iranian honey bee (Apis mellifera meda) venom. To this end, a liquid chromatography-electrospray ionization-ion trap tandem mass spectrometry (LC-ESI-IT-MS/MS) approach was employed. Melittin is the main toxic peptide of honey bee venom with various biological and pharmacological activities. It was extracted with...
متن کاملA fragmentation study of isoflavones in negative electrospray ionization by MSn ion trap mass spectrometry and triple quadrupole mass spectrometry.
This study has elucidated the fragmentation pathway for deprotonated isoflavones in electrospray ionization using MS(n) ion trap mass spectrometry and triple quadrupole mass spectrometry. Genistein-d(4) and daidzein-d(3) were used as references for the clarification of fragment structures. To confirm the relationship between precursor and product ions, some fragments were traced from MS(2) to M...
متن کاملA Rapid, Simple, Liquid Chromatographic-Electrospray Ionization, Ion Trap Mass Spectrometry Method for the Determination of Finasteride in Human Plasma and its Application to Pharmacokinetic Study
A fast, accurate, sensitive, selective and reliable method using reversed-phase high performance liquid chromatography coupled to electrospray ionization ion trap mass spectrometry was developed and validated for the determination of finasteride in human plasma. After protein precipitation with perchloric acid, satisfactory separation was achieved on a Zorbax Eclipse® C8 analytical column u...
