1. Name two gases that can be used in Gas Chromatography.

2. In gas chromatography, the mobile phase is a liquid. TRUE or FALSE?

3. Name three detectors used in gas chromatography.

4. State three parameters in Gas Chromatography that affect resolution.

Answer :

Final answer:

The gases used in gas chromatography are helium and nitrogen. The mobile phase in gas chromatography is a gas, not a liquid. Three detectors commonly used in gas chromatography are the FID, TCD, and ECD. The resolution of gas chromatography can be affected by the column length, column temperature, and flow rate.

Explanation:

Name two gases that can be used in Gas Chromatography:

  • Helium
  • Nitrogen

In gas chromatography, the mobile phase is a liquid.

FALSE. The mobile phase in gas chromatography is a gas.

Name three detectors used in gas chromatography:

  • Flame Ionization Detector (FID)
  • Thermal Conductivity Detector (TCD)
  • Electron Capture Detector (ECD)

Three parameters in Gas Chromatography that affect resolution:

  • Column length
  • Column temperature
  • Flow rate
