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.

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 difference between partition chromatography and adsorption chromatography?
The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.
Why reverse phase chromatography is so called?
Reverse-phase chromatography is so named because it involves a non-polar stationary phase and a polar mobile phase, which is the reverse of what is typically used in normal-phase chromatography. In reverse-phase chromatography, the sample molecules with lower polarity interact more strongly with the non-polar stationary phase, resulting in separation based on differences in hydrophobicity.
What is the moving solvent called in chromatography?
The moving solvent in chromatography is referred to as the mobile phase. It carries the sample through the stationary phase, allowing for separation based on differences in affinity between the components of the sample.
What is the thin layer chromatography technique used to separate complex mixtures of?
Thin layer chromatography is a technique used to separate complex mixtures of compounds based on their differential partitioning between a stationary phase (thin layer of adsorbent material on a plate) and a mobile phase (solvent moving up the plate). As the mobile phase moves through the stationary phase, compounds in the mixture will separate based on their affinity for the stationary phase and the mobile phase.
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 are the principles and methods of high performance liquid chromatography and gel chromatography?
Liquid chromatography separation of multicomponant system according to diffrent interaction of dissolved componant with stationary phase. the stationary phase and mobile phase is very wide range
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 is the difference between partition chromatography and adsorption chromatography?
The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.
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.
What called mobil phase?
The mobile phase is the liquid or gas that flows through the chromatography system, carrying the sample to be separated. It moves over the stationary phase (solid or liquid) and helps separate the components based on their interactions with the stationary phase. The choice of mobile phase depends on the type of chromatography being performed.
Why reverse phase chromatography is so called?
Reverse-phase chromatography is so named because it involves a non-polar stationary phase and a polar mobile phase, which is the reverse of what is typically used in normal-phase chromatography. In reverse-phase chromatography, the sample molecules with lower polarity interact more strongly with the non-polar stationary phase, resulting in separation based on differences in hydrophobicity.
What is the moving solvent called in chromatography?
The moving solvent in chromatography is referred to as the mobile phase. It carries the sample through the stationary phase, allowing for separation based on differences in affinity between the components of the sample.
Why do colours separate in chromatography?
Colors separate in chromatography because different compounds have different affinities for the stationary phase and the mobile phase. As the mobile phase travels through the stationary phase, compounds are carried at different rates based on their interactions with the two phases. This results in the separation of the compounds based on their unique properties.
How is chromatography done in the use of science?
In science, chromatography is typically performed by passing a mixture of substances through a stationary phase using a mobile phase. As the substances travel through the stationary phase, they separate based on their differing affinities to the stationary and mobile phases. This separation allows scientists to analyze and identify the individual components of the mixture.
Why chromatography is a physical process?
Chromatography is physical techniques for separation. The method involves the dissolution of the materials in a mobile phase, then forced through a stationary phase in which the components of the sample separate.
What is normal and reverse chromatography?
Normal-phase chromatography separates molecules based on their polarities, with the stationary phase being polar and the mobile phase being nonpolar. Reverse-phase chromatography is the opposite, with a nonpolar stationary phase and a polar mobile phase. These techniques are commonly used in analytical chemistry to separate and analyze different compounds in a sample.
