Interpretation Introduction

(a)

Interpretation:

The general expression that relates the ratio of the accelerating voltages to the ratio of corresponding m/z values is to be stated.

Concept introduction:

Peak matching is a process in which there is rapid switching between the accelerating voltages while the other conditions are kept constant.
