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 automated and can perform multiple simultaneous sampling and testing
- Modern instruments are very sensitive and can work with very small sample sizes
Exam Tip
You need to discuss the advantages of instruments over chemical testing in terms of sensitivity, speed and accuracy.
