Read each question carefully and provide your best answer based on your understanding of mass spectrometry. Refer to the provided diagram if necessary.
Observe the diagram of a mass spectrometer:
1. Which component of a mass spectrometer is responsible for converting neutral atoms or molecules into ions?
Detector
Ion source
Mass analyzer
Vacuum system
2. In a magnetic sector mass spectrometer, ions are separated based on their:
Velocity
Charge
Mass-to-charge ratio
Kinetic energy
3. The is the component that detects the separated ions and converts them into an electrical signal.
4. In mass spectrometry, fragmentation of molecules often occurs in the region, leading to characteristic patterns.
5. All ions in a mass spectrometer are deflected by the same amount, regardless of their mass.
True
False
6. Mass spectrometry can be used to determine the isotopic abundance of elements.
True
False
7. Briefly explain the purpose of the vacuum system in a mass spectrometer.
8. Describe how ions are accelerated in a mass spectrometer.
