A sample of a compound is bombarded with high-energy electrons, usually around 70 electron volts.
A sample of a compound is bombarded with high-energy electrons, usually around 70 electron volts. This causes the release of an electron to form a radical cation, which is then passes between two positively charged plates and enters an evacuated tube. Neutral and negatively charged fragments are excluded, but the positively charged ones proceed between a ring magnet which deflects them at an angle relative to their weight. Ions with a common weight pass through a collection slot in, FTP, what kind of instrument that allows scientists to determine the weight of an unknown chemical compound?
