Instrumental Methods

Machines can analyse unknown substances:

  • Used for medical purposes, police forensic work, environmental analysis, checking whether an athlete has taken drugs...
  • Advances in electronics and computing have made more advanced analysis possible


  • Can be operated by technicians whereas lab methods need trained chemists
  • More accurate than lab methods and can detect the tiniest amounts of substances
  • Much faster than lab methods and tests can be automated


  • Very expensive to buy, run and maintain the machines

Atomic absorption spectroscopy:

  • A bit like a flame test machine, used for indentifying metals
  • Patterns of light absorbed by the metals in the sample are analysed - each metal produces a different…
