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.
Principle of partition chromatography?
Chromatography in which separation is based mainly on differences be- tween the solubility of the sample components in the stationary phase (gas chromatography), or on differences between the solubilities of the compo- nents in the mobile and stationary phases (liquid chromatography)
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 the significance of the stationary phase in gas chromatography?
The stationary phase is the medium that is used to react with the mobile phase. The molbile phase is sent through the column. The stationary phase is inside the column and reacts with your carrier liquid (mobile phase) which contains the sample that you want to be analyzed. Stationary phase is different for every column because you need different mediums for different tests.
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 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

What does chromatography mean in science?
Chromatography is a way to separate mixtures. You start by dissolving your sample in a mobile phase. This mobile phase travels through a structure, the stationary phase. Depending on how much the compounds in the mixture like or dislike the stationary phase they will move at different speeds throughout the stationary phase. This allows for slower moving compounds to separate from fast moving compounds and allowing you to collect different compounds from a single mixture.
What are the advantages of thin layer chromatography?
There are two big advantages of thin later chromatography. They are 1. simplicity and 2. economy. The experimental setup is simle and eay to perform since it only involves spotting the stationary phase with the sample and placing one edge of the stationary phase plate in the mobile phase reservoir. The process is economical since the equipment required for the experiment is rather minimal. It only requires the TLC stationary phase, which is many cases is Silica and can be bought from a variety of commercial analytical chemistry lab suppliers. The mobile phase is generally prepared in the laboratory. In addition, the mobile phase travells up the stationary phase by capillary action, unlike in other chromatography setups where the mobile phase has to be pumped.
What is Chromatography and what is it for?
Chromatography is an analytical method to separate the compounds from the two immiscible phases,one being a mobile phase and another being a stationary phase. It is used in petroleum industry,pharmaceutical industry.
Why reverse phase chromatography is so called?
The first chromatography used was with polar stationary phase and non polar mobile phase, called normal phase. So, later when this was reversed by using polar mobile phase and non polar stationary phase was called reversed phase. Although reversed phase implies that it is less used, it is not the case. RPLC rose to success around the 1970s as NPLC dropped off.
What is the purpose of the filter paper inside the developing chamber in chromatography?
Paper is the (solid) stationary phase, 'sucking' up the liquid, mobile (= transporting) phase
What is the mobile phase of ion exchange chromatography?
The mobile phase as indicated is the moving phase. Either the mobile or stationary phase is polar and the other is Non-polar. A common polar phase is Methanol, and non-polar is hexane
