Chromatography (/ˌkroʊməˈtɒɡrəfi/; from Greek χρῶμα chroma which means "color" and γράφειν graphein "to write") is the collective term for a set of laboratory techniques for the separation of mixtures.
The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus changing the separation.
Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for more advanced use (and is thus a form of purification). Analytical chromatography is done normally with smaller amounts of material and is for measuring the relative proportions of analytes in a mixture. The two are not mutually exclusive.

Take a jar containing some water.
Put the filter paper in it such that the drop of ink is just above the water level.
After sometime, the water starts gradually rising up by capillary action.
As the water moves up, it takes the dyes present in the ink along with it.

Chromatography
The term chromato means colour and graphy means to write. Chromatography technique is widely used for the separation of molecules from a mixture. Chromatography separation is based on the difference in solubility of sample molecules in the mobile phase and the stationary phase. The mobile phase is also known as Eluent. The mobile phase leaving the column is called eluate and the sample leaving the column is called eluite.

Our topic for today is Chromatography.

Let us find out by the process of paper chromatography.
Chromatography is a technique of separating two or more dissolved solids which are present in a solution in very small quantities.
Take a strip of filter paper.

Put a small drop of ink on the center of the line.

Take a jar containing some water.
Put the filter paper in it such that the drop of ink is just above the water level.
After sometime, the water starts gradually rising up by capillary action.
As the water moves up, it takes the dyes present in the ink along with it.
Slowly, we start seeing some different colors on the paper as the water rises up, these are the different dyes present in the ink.
Different dyes have different solubility levels and travel at different speeds as the water rises up.
As a result, we see different colors at different heights and the dyes get separated.
Hence, in this way paper chromatography is used to separate the different colors in a dye.

Chromatography (/ˌkroʊməˈtɒɡrəfi/; from Greek χρῶμα chroma which means "color" and γράφειν graphein "to write") is the collective term for a set of laboratory techniques for the separation of mixtures.
The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus changing the separation.
Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for more advanced use (and is thus a form of purification). Analytical chromatography is done normally with smaller amounts of material and is for measuring the relative proportions of analytes in a mixture. The two are not mutually exclusive.
Representational Image(BrigadeGroup). “I’ve lived in maybe 10 apartments, and this illegal retention of deposit has happened every single time,” Varun Mayya wrote, striking a chord with many users who shared similar experiences. Read the post here..
How will Peacock retain these new subscribers? Early data indicates that single-event sports may not support long-term retention ... shows and familiar programming that truly anchor audiences over time.
At the same time, he said the data isn’t necessarily surprising, given that the nationwide rate of chronic absenteeism doubled during the COVID-19 pandemic ... Other times, it’s a question of whether the student wants to go to school.
