GC-MS
- choose a substance to separate
- It will travel through a column carried by a gas
- the column is packed with solid material
- the different substances in the compound travel at different speeds
- the time taken for a substance to travel through the column can be used to help identify the sunstance
- the number of peaks on the output shows the number of compounds present
- the position of the peaks on the output indicates the retention time
- the output can be linked to a mass spectrometer which can be used to identify the substances leaving the end of the column
- a mass spectrometer can identify substances quickly and accurately
- the mass spectrometer can give the molecular mass of each substance
- the molecular mass is given by the molecular ion peak
- the molecular mass is given by the molecular ion peak
