How are Toxic Substances Detected in Biological Samples?
In biological samples such as blood, urine, or tissue, toxic substances are detected through a combination of sample preparation, extraction, and analysis. Sample preparation involves making the sample suitable for analysis, often through dilution or concentration. Extraction techniques like solid-phase extraction help isolate the toxin from the biological matrix. Analytical methods like GC-MS or LC-MS are then used to identify and quantify the substance.
