Drug Testing and Addiction

Method of separating and tentatively identifying components of a liquid mixture.

• Ultraviolet Spectrophotometry

• Thin-layer chromatography (TLC)

• Gas Chromatography (GC)

• Mass spectrometry (MS)

• Infrared spectrophotometry

Measures the absorption of radiation as it passes through the tests material. Provides a complex pattern that can specifically identify a substance.
