Enlist the factors involved in selecting a suitable stationary phase for gas chromatograph
Accepted Answer
Factors involved in selecting a suitable stationary phase for gas chromatography include:
1. Sample Polarity: Polar stationary phases are suitable for polar analytes, while nonpolar stationary phases are suitable for nonpolar analytes.
2. Boiling Point: Stationary phases with higher boiling points are suitable for higher boiling point analytes.
3. Column Temperature: The stationary phase should be stable at the operating temperature of the column.
4. Selectivity: The stationary phase should provide good separation for the target analytes.
5. Capacity: The stationary phase should have sufficient capacity to retain the target analytes.
6. Cost: The stationary phase should be affordable.
7. Availability: The stationary phase should be readily available.
8. Compatibility with GC system: The stationary phase should be compatible with the GC system, including the injector and detector.
