Question
__________method is used for calculating mass to charge for one or more molecules.
- Mass spectroscopy
- Light scattering
- Hydrodynamic
- Centrifugal
Hint:
Mass spectrometry (MS) is used to measure the mass-to-charge ratio of ions.
The correct answer is: Mass spectroscopy
Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio.
Mass spectroscopy method is used for calculating mass to charge for one or more molecules.
