Observe the diagram of a mass spectrometer below:
1. Mass spectroscopy is a technique used to measure the -to-charge ratio of ions.
2. In a mass spectrometer, samples are first vaporized and then to form charged particles.
3. The component responsible for separating ions based on their mass-to-charge ratio is the analyzer.
1. Which of the following is NOT a main component of a mass spectrometer?
Ion source
Mass analyzer
Detector
Spectrophotometer
2. What is the primary purpose of the detector in a mass spectrometer?
To ionize the sample
To separate ions by mass
To record the abundance of ions
To vaporize the sample
1. Mass spectroscopy can be used to determine the molecular weight of a compound.
True
False
2. All ions produced in the mass spectrometer have the same charge.
True
False
1. Briefly explain how a mass spectrometer separates ions of different masses.
2. List two real-world applications of mass spectroscopy.
