What are the Common Optical Techniques Used in Toxicology?
There are several optical techniques widely used in toxicology, each with unique advantages:
Spectrophotometry: Measures the amount of light absorbed by a sample at specific wavelengths, useful for quantifying known toxic substances. Fluorescence Spectroscopy: Utilizes the emission of light by a substance that has absorbed light, ideal for detecting specific toxins that fluoresce. Raman Spectroscopy: Provides molecular fingerprints by detecting vibrational, rotational, and other low-frequency modes in a system. Infrared Spectroscopy: Uses the infrared region of the electromagnetic spectrum to identify and quantify organic compounds, often used in conjunction with other techniques. Mass Spectrometry with Optical Detectors: Combines mass spectrometry with optical detectors to enhance sensitivity and specificity.
