Which of the following are true? You may select more than one answer choice. The incorrect answers will be penalized.
a. Flame atomic absorption has a higher sensitivity than inductively coupled plasma-mass spectrometry.
b. Atomic linewidths are broadened by the Doppler effect, which arises because atoms moving toward the light source see a higher frequency of light than atoms moving away from the light source.
c. The Doppler linewidth is dependent on the temperature of the flame or plasma and the mass of the atom.
d. in flame spectrophotometry, precision is higher in absorption than in emission measurements.
