1. In a magnetic sector (single-focusing) mass spectrometer, it might be reasonable under some circumstances to monitor one m/z value, to then monitor a second m/z, and to repeat this pattern in a cyclic manner. Rapidly switching between two accelerating voltages while keeping all other conditions constant is called peak matching. a) Derive a general expression that related the ratio of the accelerating voltages to the ratio of the corresponding m/z values. b) Use this equation to calculate m/z of unknown peak if m/z of the ion used as a standard, CF3 is 69.00 and the ratio of Vunknown/Vstandard is 0.956134. c) Draw a simple schematics of magnetic sector analyzers d) What causes band broadening in magnetic section analyzers
