What Types of Detectors are Used in GC for Toxicology?
Several types of detectors can be used with GC, but some are particularly important in toxicology:
- Flame Ionization Detector (FID): Commonly used for organic compounds, FID is highly sensitive and provides a wide dynamic range.
- Electron Capture Detector (ECD): Highly sensitive to halogenated compounds, ECD is useful for detecting pesticides and polychlorinated biphenyls (PCBs).
- Mass Spectrometry (MS): When combined with GC (GC-MS), it offers unparalleled specificity and sensitivity, making it the gold standard for identifying unknown compounds.
