Identify the detector or detectors that can be used for gas chromatography for the detection of each analyte.

A. Flame Ionization Detector (FID)
B. Mass Spectrometer (MS)
C. Thermal Conductivity Detector (TCD)
D. All of the above

Answer :

Final answer:

The detectors used for gas chromatography include the Flame Ionization Detector (FID) for organic compounds, Mass Spectrometer (MS) for identification based on mass-to-charge ratios, and Thermal Conductivity Detector (TCD) to detect all types of analytes.

Explanation:

To identify the detector or detectors that can be used for gas chromatography for the detection of each analyte:

  • (a) Flame Ionization Detector (FID) is typically used for detecting organic compounds and is suited for analytes that can be ionized in a flame.
  • (b) A Mass Spectrometer (MS) is widely utilized to identify substances based on their mass-to-charge ratios. It is often coupled with gas chromatography for detailed chemical analysis.
  • (c) A Thermal Conductivity Detector (TCD) measures changes in thermal conductivity and can detect all types of analytes including those that are not ionizable.
  • (d) All of the above detectors can be used for gas chromatography depending on the analyte's properties and the desired level of analysis.
