Interpretation:
The difference between the gas-liquid and gas-solid chromatography is to be stated.
Concept introduction:
Chromatography is a technique or method used to separate the constituents of a mixture. The mixture is first dissolved in a type of fluid that is known as the mobile phase. This phase is carried through the stationary phase. The constituents travel at different speeds due to which they get separated. There are two types of chromatography methods. These include gas-solid chromatography and the gas-liquid chromatography
Answer to Problem 27.1QAP
In gas-solid chromatography, the solid surface is a stationary phase, which retains the analytes on it by the process of physical adsorption. In gas-liquid chromatography, the liquid that is stopped on a solid is the stationary surface.
Explanation of Solution
The differences between the gas-liquid and gas-solid chromatography are as mentioned below.
Gas-Solid Chromatography | Gas-Liquid Chromatography |
The solid state is the stationary phase. | The liquid state is the stationary phase. |
Gas-Solid Chromatography can be used at high temperatures. | Gas-Liquid Chromatography cannot be used at high temperatures. |
The stationary phase is stable. | The stationary phase is not stable. |
The stationary phase is deposited in the column as a solid compound. | The stationary phase is deposited in the column as a liquid film. |
Thus, in gas-solid chromatography, the solid surface is a stationary phase, which retains the analytes on it by the process of physical adsorption. In gas-liquid chromatography, the liquid that is stopped on a solid is the stationary surface.
