The ion-accelerating voltage in a particular quadrupole mass spectrometer is V. How long will it take a singly charged cyclohexane ion to travel the cm length of the rod assembly? Assume that the initial velocity of the ion in the z direction is zero.
When a magnetic sector instrument was operated with an accelerating voltage of , a field ofwas required to focus thedata-custom-editor="chemistry" on the detector.
(a) What range of field strengths would be required to scan the mass range between 16 and 300, for singly charged ions, if the accelerating voltage is held constant?
(b) What range of accelerating voltages would be required to scan the mass range between 16 and 300, for singly charged ions, if the field strength is held constant?
How do gaseous and desorption sources differ? What are the advantages of each?
The following figure is a simplified diagram of a a commercially available EI source.
(a) What voltage must be applied between the filament and target so that electrons interacting with molecules at the point marked SS (sample source) will have 70 eV of kinetic energy?
(b) What will happen to a molecule that diffuses toward the filament and is ionized at point P?
