Mass Spectrometers

Mass spectrometers are an analytical apparatus used for separating isotopes, molecules, and molecular fragments according to mass. The mass spectrometer produces charged particles (ions) from the chemical substances and then uses electric and magnetic fields to measure the mass or weight of the charged particles.

What are Mass Spectrometers Used For?

Mass spectrometers are used to measure the mass-to-charge ratio (m/z) of one or more molecules present in a sample. These measurements are often be used to calculate the exact molecular weight of the sample components as well to identify unknown compounds via molecular weight determination, to quantify known compounds, and to determine structure and chemical properties of molecules.
