Forensic Chemistry > 1. The job of the forensic chemist is to identify materials and trace their origins > 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.
