III detector.
IV mass separator.
V accelerator.

Question

Quizplus · Accepted Answer

The three essential components of any mass spectrometer are the ion source, detector, and mass separator. The ion source ionizes the sample, the mass separator separates the ions based on their mass-to-charge ratio, and the detector detects the separated ions. The decelerator and accelerator are not essential components of a mass spectrometer, although they may be used in some specific types of mass spectrometers. Therefore, option A, which includes the ion source, detector, and mass separator, is the correct choice.
