C12.6 Instrumental analysis


Instrumental methods of analysis:

Instrumental methods of analysis rely on machines. There are several different types of instrumental analysis. Some are suitable for detecting and identifying elements, while others are better suited to compounds. In general, instrumental methods of analysis are:

  • Fast
  • Accurate (they reliably identify elements and compounds)
  • Sensitive (they can detect very small amounts of a substance in a small amount of sample)

Disadvantages include:

  • Usually very expensive
  • Takes special training to use
  • Gives results that can often be interpreted only by comparison with data from known substances

Flame Emission Spectroscopy:

All atoms give off light when heated, although sometimes this light is not visible to the human eye…
