Question:
Following are the desirable properties of the liquid phase used in GLC EXCEPT for one of the following. Identify the same.
Following are the desirable properties of the liquid phase used in GLC EXCEPT for one of the following. Identify the same.
Show Hint
Desirable GLC liquid phases should be inert, have low vapor pressure, and low viscosity.
Updated On: Jun 16, 2025
- It should be inert to the analytes
- It should have high viscosity at operating temperature
- It should have low vapour pressure at the operating temperature
- It should have a high resolving power
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In GLC (Gas-Liquid Chromatography), the stationary phase (liquid) should have low viscosity to ensure good coating and efficient separation. High viscosity can hinder flow and reduce efficiency.
