Question

In Energy dispersive system, the energy level and the number of pulses is related to which of the following?

(a) Amount of sample, element involved

(b) Element involved, concentration of the element

(c) Concentration of the element, element involved

(d) Number of atoms, amount of sample

The question was posed to me during an interview.

My question comes from X-Ray Fluorescent Spectrometer in section X-Ray Spectrometers of Analytical Instrumentation

Answer 1

The correct choice is (b) Element involved, concentration of the element

For explanation I would say: In Energy dispersive system, the energy level is related to the element involved. The number of pulses is related to the concentration of the element involved.
