Abstract: Mass spectrometry systems and methods are disclosed. Briefly described, one embodiment of the mass spectrometry system, among others, includes a mass spectrometer, a laser generator, and a sample substrate. The mass spectrometer includes a first end and a second end and the laser generator produces a laser radiation beam that travels along a first path. The sample substrate holds a sample at the first end of the mass spectrometer, where the sample produces a plurality of ions that travel along a second path that is substantially parallel the first path but towards the second end of the mass spectrometer.
