There are several types of detectors used in gas chromatography, each with its specific applications in catalysis: 1. Flame Ionization Detector (FID) - Commonly used for hydrocarbons and organic compounds. 2. Thermal Conductivity Detector (TCD) - Useful for detecting inorganic gases and permanent gases. 3. Mass Spectrometer (MS) - Provides detailed molecular information and is highly sensitive. 4. Electron Capture Detector (ECD) - Excellent for detecting halogens and nitrates.
