Mass spectrometry is an analytical technique that measures the mass-to-charge ratio of ions. The results are typically presented as a mass spectrum, a plot of relative abundance versus mass-to-charge ratio (m/z). This technique is widely used for identifying unknown compounds, determining isotopic composition, and elucidating the structure of molecules.
1. Which of the following is the primary information obtained from a mass spectrum?
Molecular formula
Mass-to-charge ratio (m/z)
Melting point
Boiling point
2. The process of converting neutral molecules into ions in a mass spectrometer is called:
Chromatography
Ionization
Spectroscopy
Distillation
3. The component of a mass spectrometer responsible for separating ions based on their m/z ratio is the .
4. In mass spectrometry, the most abundant ion in the spectrum is referred to as the peak.
5. Briefly explain the purpose of the vacuum system in a mass spectrometer.
6. How can mass spectrometry be used to distinguish between isotopes of an element?
7. Mass spectrometry can be used to determine the exact molecular weight of a compound.
True
False
8. The detector in a mass spectrometer measures the kinetic energy of the ions.
True
False
