Instrumental Methods (AQA GCSE Chemistry): Revision Note

Advantages of instrumental methods

• Advancements in technology and computing have allowed for the development of instruments designed to analyse chemical substances

• Methods of analysis include X-ray, Infra-Red and Mass Spectroscopy, Gas Chromatography and Flame Photometry

• These analytical techniques require modern day instruments which are a vital part of chemistry laboratories

• The advantage of using these instruments over more traditional methods include:

  • They provide greater accuracy

  • They are faster and easier to use

  • They are more sensitive than non-instrumental methods
