Assume you are trying to develop a GC-MS instrument which would be used in the field (unit must be portable and robust) for the identification of relatively small compounds (<500 g/mol). Assuming the GC (gas chromatograph) will separate the components prior to the MS, what type of ionization method (i.e. EI, CI, ESI, MALDI) and detector (i.e. magnetic sector, magnetic double sector, quadrupole, ion trap, or time-of flight) would you choose and why?
