Question
Question 3: Mass Spectrometer
Consider a mass spectrometer with a 200.00 mT magnetic field and an 8.0000 cm spacing between the
entrance and exit holes.
To five significant figures, what accelerating potential differences AV are required to detect the ions
(a) 02+, (b) N2+, and (c) CO+?
Note: the missing electron is less than 0.001 u and is not relevant at this level of precision.
Although N2+ and CO+ both have a nominal molecular mass of 28, they are easily distinguished by virtue
of their slightly different accelerating voltages. The conversion between atomic mass units and
kilograms is 1 u = 1.6605 x 10-27 kg, and the charge of each ion is e = 1.6022 × 10-1⁹ C.
