The detection of contaminants involves various analytical techniques. Some common methods include:
Chromatography: Techniques like gas chromatography (GC) and liquid chromatography (LC) are used to separate and analyze complex mixtures. Mass Spectrometry (MS): Often coupled with chromatography, MS identifies substances based on their mass-to-charge ratio. Spectroscopy: Techniques such as atomic absorption spectroscopy (AAS) and infrared spectroscopy (IR) are used to detect and quantify elements and compounds. Bioassays: These are used to assess the biological activity of a substance, often using living cells or tissues.
