What is stationary phase and mobile phase?
mobile phase is the phase that consist of the analyte and stationary phase is the phase that is standstill
What is mobile and stationary phase in Chromatography?
In chromatography, the mobile phase is the solvent that carries the sample through the stationary phase. The stationary phase is the material that interacts with the components of the sample, causing separation based on differences in their affinity for the stationary phase.
How does the polarity of the stationary phase affect the separation of compounds?
The polarity of the stationary phase is critical in determining the interactions between the compound and the stationary phase. Compounds with similar polarity to the stationary phase will interact more strongly and be retained longer, leading to better separation. Conversely, compounds that are less polar than the stationary phase will elute faster.
What is the difference between the stationary phase and the mobile phase in chromatography?
stationary phase stays at the bottom of the paper chromatography while mobile phase is moving on the stationary phase and move on stationary phase till it gets its right place on the top of the paper or somwhere else.
What is the significance of the stationary phase in gas chromatography?
The stationary phase in gas chromatography is crucial because it interacts with the components of the sample being analyzed, causing them to either be retained or move at different rates through the column. This separation process allows for the identification and quantification of individual components in the sample mixture. The stationary phase can be tailored to enhance the separation efficiency based on the specific properties of the compounds being analyzed.

What is used as the stationary phase in paper chromatography?
The stationary phase in paper chromatography is the paper itself.

What is a method of separation that employs a system with two phases of matter a mobile phase and a stationary phase?
Chromatography is a method of separation that employs a system with two phases of matter – a mobile phase and a stationary phase. The mobile phase carries the mixture to be separated through the stationary phase, where the components separate based on their interactions with the stationary phase.
Why H2O is stationary phase in chromatography?
H2O (water) is not typically used as a stationary phase in chromatography. Instead, it is commonly used as a mobile phase due to its excellent solvating capabilities. Stationary phases in chromatography are usually solid supports or coated surfaces that interact with the analytes being separated.
What are the differences between reverse phase and normal phase chromatography?
Reverse phase chromatography and normal phase chromatography are two types of chromatographic techniques that differ in the polarity of the stationary phase and mobile phase. In reverse phase chromatography, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase chromatography, the stationary phase is polar and the mobile phase is nonpolar. This polarity difference affects how compounds interact with the stationary phase, leading to differences in separation and elution times.
What are the key differences between HPLC reverse phase and normal phase chromatography techniques?
In reverse phase HPLC, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase HPLC, the stationary phase is polar and the mobile phase is nonpolar. This difference in polarity affects how compounds interact with the stationary phase, leading to variations in separation and elution times.
What is the role of the stationary phase in paper chromatography?
The stationary phase in paper chromatography acts as a medium for separating different components of a mixture based on their affinity for the stationary phase. It helps to slow down the movement of the components as they travel through the paper, allowing for the separation based on their different interactions with the stationary phase.
What are mobile phase and stationary phase?
stationary phase is the solid called the filter paper and mobile phase is the liquid or organic solvent present in the developing tank or beaker by ayesha zulfiqar

What are the key differences between HPLC normal phase and reverse phase chromatography techniques?
In normal phase HPLC, the stationary phase is polar and the mobile phase is nonpolar, while in reverse phase HPLC, the stationary phase is nonpolar and the mobile phase is polar. This difference in polarity affects how compounds interact with the stationary phase, leading to different separation mechanisms and selectivity in each technique.
