Write a note on mass spectrometry.

A mass spectrometer produces charged particles (ions) from the chemical substances that are to be analyzed. The mass spectrometer then uses electric and magnetic fields to measure the mass ("weight") of the charged particles.
Basic Principle. A mass spectrometer generates multiple ions from the sample under investigation, it then separates them according to their specific mass-to-charge ratio (m/z), and then records the relative abundance of each ion type.
Mass spectrometry (also called mass spec) provides valuable information about the structure of molecular compounds. Organic chemists can use a mass spectrometer to ionize (or 'smash') a molecular compound in gaseous form, sort the fragments, and then identify the molecule fragments based on their molecular weights.
The substance is bombarded with a beam of electrons so the atoms or molecules it contains are turned into ions. ... A computerized, electrical detector records a spectrum pattern showing how many ions arrive for each mass/charge. This can be used to identify the atoms or molecules in the original sample
