Q

first step of mass spectroscopy (vaporisation)

A

The sample is turned to a gas so atoms and molecules are seperated

Q

second step of mass spectroscopy (ionisation)

A

A heated filament gives out electrons to pass through the gas, where they knock out other electrons from the atom to form a positive ion

Q

third step of mass spectroscopy (Acceleration)

A

An electrical field is applied to accelerate the positive ions so they have the same ke

Q

last step of mass spectroscopy (detection)

A

Ions with the correct mass:charge ratio will be detected. If magnetic field stays constant while while the electrical field is varied,one type of molecule after another will be detected, a complete spectrum will be obtained
