In a magnetic sector mass spectrometer, would the measured mass increase or decrease if you:
1). Increase the accelerating potential
2). Decrease the magnetic field
Thank you for the help!
Homework Answers
formula is given by
acceleration potential in the source region (V) and the mass to charge ratio (m/z) of the ion.
mass (m) and the velocity (v).
so from above formula it is clear
m ∝ B2 ( directly proportional )
and m ∝ 1/v (inversely proportional)
so
1)
so if we increase the potential the mass will decrease ( inversely proportional )
2)
and if we Decrease the magnetic field the mass will also Decrease ( directly proportional )
Good Luck !!
let me know in a comment if there is any problem or
doubts

How does changing the magnetic field strength in a magnetic sector mass spectrometer affect which ions reach the detector? answers are: increase in magnetic field strength = ions with larger m/z reaching the detector, increase in magnetic field strength = ions with smaller m/z reaching the detector, or decrease in magnetic field strength = ions with larger m/z reaching the detector How does changing the accelerating voltage in a magnetic sector mass spectrometer affect which ions reach the detector? answers...

(Figure 1) shows a mass spectrometer, an analytical instrument used to identify the various molecules in a sample by measuring their charge-to-mass ratio q/m. The sample is ionized, the positive ions are accelerated (starting from rest) through a potential difference ΔV, and they then enter a region of uniform magnetic field. The field bends the ions into circular trajectories, but after just half a circle they either strike the wall or pass through a small opening to a detector. As...

In a mass spectrometer, a student needs to find the strength of
the electric field that is needed in the velocity sector if a
single charged particle with a mass of 7.971x10^-26 kg after
leaving the velocity sector is to hit the ceiling 0.036 m above the
opening where it enters the region with only magnetic field. There
is no E field. The value of the magnetic field is 0.025 T in the
entire mass spec.

In a common type of mass spectrometer, a beam of ions is passed through a velocity sector with crossed electric and magnetic fields. What is the purpose of the velocity sector? to strip loose electrons from the ions to decrease the kinetic energy of the ions to prevent the ions from traveling in a circular path to block all ions except those with specific speeds
