In a magnetic sector (single-focusing) mass spectrometer, it might be reasonable under some circumstances to monitorone mlz value, to then monitor a second m/z, and to repeat this pattern in a cyclic manner. rapidly switching between twoaccelerating voltages while keeping all other conditions constant is called peak matching.(a) derive a general expression that relates the ratio of the accelerating voltages to the ratio of the correspondi ng mlzvalues.(b) use this equation to calculate mlz of an unknown peak if mlz of the ion used as a standard, cf3 +, is 69.00 and the ratioof vunknown/ vstandard is 0.965035.( c) based on your answer in part (b ), and the assumption that the unknown is an organic compound that has a mass of143, drnw some conclusions about your answer in part (b ), and about the compound.
