Multi-Dimensional Fragmentation of Anthocyanins from Rose Petals by Ion Trap – Time-of-Flight (IT-TOF) Mass Spectrometry
نویسندگان
چکیده
A Shimadzu high performance liquid chromatography – ion trap – time of flight mass spectrometer (LCMS-IT-TOF) was used to aid in the identification of anthocyanin species in rose petals. The effects of varying the parameters which control the collision energy and the collision gas were observed on cyanidin-3,5-diglucoside and its related mono-glucoside and anthocyanidin fragment signals. Further variation in these parameters were used to optimize iterative multi-stage fragmentation (up to MS ) in order to elucidate the fragmentation pathway of cyanidin-3,5diglucoside.

A linear octopole trap interface for an ion mobility time-of-flight mass spectrometer has been developed for focusing and accumulating continuous beams of ions produced by electrospray ionization. The interface improves experimental efficiencies by factors of approximately 50-200 compared with an analogous configuration that utilizes a three-dimensional Paul geometry trap (Hoaglund-Hyzer, C.

متن کاملAn ion trap storage/time-of-flight mass spectrometer
An ion trap/time-of-flight (TOF) mass spectrometer combination has been developed in order to combine the storage capabilities of an ion trap with the speed and resolution of a time-of-flight device. The ion trap is an rf quadrupole trap which operates in the total storage mode, i.e., with the dc voltage=0 on the end caps and rf voltage on the ring electrode. The trap has an ion storage time of...
