What are the Common Types of Analytical Instruments Used?
Several types of analytical instruments are used in toxicology, each with its specific applications and strengths. Some of the most commonly used instruments include:
Gas Chromatography (GC): Used for separating and analyzing compounds that can be vaporized without decomposition. It is commonly used to detect volatile organic compounds. Liquid Chromatography (LC): Ideal for separating non-volatile and thermally unstable compounds, frequently used in drug analysis and toxicology studies. Mass Spectrometry (MS): Often coupled with GC or LC, this technique provides detailed information about the molecular weight and structure of compounds. Atomic Absorption Spectroscopy (AAS): Utilized for detecting metals and metalloids in samples, essential for analyzing environmental pollutants. Infrared Spectroscopy (IR): Helps in identifying organic compounds by measuring the vibration of chemical bonds.
