10 Questions
What is mass spectrometry used for?
Mass spectrometry is used to measure the mass-to-charge ratio of ions.
What is a mass spectrum?
A mass spectrum is a plot of intensity as a function of the mass-to-charge ratio.
How is a sample ionized in mass spectrometry?
A sample can be ionized by bombarding it with a beam of electrons.
What happens to the ions (fragments) in mass spectrometry after ionization?
The ions (fragments) are then separated according to their mass-to-charge ratio.
What can mass spectra be used to determine?
Mass spectra can be used to determine the elemental or isotopic signature of a sample, the masses of particles and molecules, and the chemical identity or structure of molecules and compounds.
Which of the following is NOT true about mass spectrometry?
Mass spectrometry is only used for complex mixtures
What type of plot is a mass spectrum?
A plot of intensity as a function of the mass-to-charge ratio
How are samples ionized in mass spectrometry?
By bombarding them with a beam of electrons
What happens to the sample's molecules during ionization in mass spectrometry?
They break up into positively charged fragments
