GC Detector Matching Explained
This section provides the correct matching between Gas Chromatography (GC) detectors listed in LIST-I and their corresponding applicable sample types from LIST-II.
- A. Flame ionization detector (FID) correctly matches with II. Hydrocarbons. FID is highly sensitive to organic compounds, especially hydrocarbons.
- B. Thermal conductivity detector (TCD) is correctly matched with III. Universal detector. TCD can detect a wide range of substances based on their thermal conductivity difference from the carrier gas.
- C. Mass spectrometer (MS) is correctly matched with I. Tunable for any species. MS can identify specific compounds by analyzing their mass-to-charge ratio and fragmentation patterns.
- D. Photo ionization detector (PID) is correctly matched with IV. Compounds ionized by UV radiation. PID works by ionizing compounds using UV light, effective for molecules with ionization potentials matching the lamp energy.
The correct combination is A-II, B-III, C-I, D-IV.
