A Mass Spectrometer Works by Ionizing Atoms or Molecules, and Then

question 140

Multiple Choice

A mass spectrometer works by ionizing atoms or molecules, and then accelerating them through oppositely charged plates. The mass is obtained by

• A) measuring the force of impact on a detecting screen, and then calculating the mass using force = mass * acceleration.
• B) suspending the ions in an applied electric field, and then calculating mass by the setting the downward gravitational force equal to the upward electrostatic force.
• C) measuring the magnitude of deflection as the ions pass through a magnetic field to obtain the charge-to-mass ratio, and then calculating the mass from that ratio.
• D) measuring the time it takes for the ions to hit the detector at a known distance to calculate the acceleration, and then calculating mass from force = mass * acceleration.
