Fig. 6. A sample mass spectrum, generated in mass scanning mode. The primary ion is O⁺₂ (32 amu). This sample was emitting NH₃ and had been treated with pyridine and dimethylamine. Consequently, peaks from these species (17 amu-NH₃, 44 and 45 amu-dimethylamine, and 79 amu-pyridine) are also present, demonstrating that multiple emissions can be readily analyzed.
