Read each question carefully and answer to the best of your ability. For multiple choice questions, circle the correct option. For fill-in-the-blank questions, complete the sentence with the appropriate term. For short answer questions, provide a concise explanation.
1. Which of the following is the primary purpose of a mass spectrometer?
To measure the absorption of light by a sample
To determine the elemental composition and molecular structure of a sample
To separate components of a mixture based on boiling points
To analyze the crystalline structure of solids
2. In a mass spectrometer, what is the role of the ionization chamber?
To detect ions
To accelerate ions to high speeds
To convert neutral atoms or molecules into ions
To separate ions based on their mass-to-charge ratio
3. The deflection of ions in a mass spectrometer is dependent on their mass-to-charge ratio and the strength of the field.
4. In mass spectrometry, fragmentation patterns can provide information about the structure of a molecule.
