Question- Part 1- Suppose two compounds of known identity but with distinctive mass spectra cannot be resolved chromatographically. How could they be individually quantitated by MS as they co-elute from a column.
Part 2- Would the kinetic energy of a nitrogen (2s) electron be higher or lower than a nitrogen (1s) electron using the same x-ray excitation source and why?
I want to know how this is done please show all steps in detail
