The Progress in Analytical Chemistry

Discuss, using a recent example, how progress in analytical chemistry and changes in technology can alter the outcome of a forensic investigation

One technique that can be used for forensic investigation is chromatographic analysis. These are:

  • Thin layer chromatography (TLC)
  • Gas chromatography (GC)
  • High performance liquid chromatography (HPLC)

Technological advances lead to the development of more techniques that can be used in analytical investigations. The limitations of a certain technique could be resolved by introducing new techniques. This greatly helps the forensic chemists to achieve better results in shorter period of time.
