Which of the following statement is false for mass spectroscopy?

Mass spectroscopy is used to identify unknown compounds within a sample, and to elucidate the structure and chemical properties of different molecules

Particle are characterized by their mass to charge ratios (m/z) and relative abundances

This technique basically studies the effect of ionizing energy on molecules

This technique can be used on all state of matter
