The effect on resolution of increasing voltage from 28 to 120 kV.
(a) What is the expected ratio of migration times (t120 kV/t28 kV) in the two experiments? Measure the migration times for peak 1 and find the observed ratio.
(b) What is the expected ratio of plates (N120 kV/N28 kV) in the two experiments?
(c) What is the expected ratio of bandwidths (σ120 kV/σ28 kV)?
(d) What is the physical reason why increasing voltage decreases bandwidth and increases resolution?
