Mass Spectrometer Process
Cards in this deck (4)
- 1IonisationA gaseous sample is bombarded with high energy electrons to form positive ions
- 2Accelerationan electric field accelerates the positive ions to high speed
- 3Deflectiona magnetic field deflects the ions according to their mass/charge ratio (heavier ions deflected less)
- 4Detectionions with the correct mass/charge ratio pass through a slit and are detected by an instrument such as an electrometer. The signal is then amplified and recorded
