ascending chromatography is a type of chromatography in which chromatic substance is in mobile phase and moving from bottom to top.
similarly in descending chromatography mobile phase moving from top to bottom.
Carotene travels the farthest in chromatography of leaf pigments because it is the least soluble in the chromatography solvent. This means it interacts less with the solvent and more with the chromatography paper, allowing it to move further up the paper before the solvent front stops it.
Stationary Phase is a layer or coating on the supporting medium that interacts with the analytes and is fixed in a place either in column or a planar surface. It can be solid, liquid, gel or solid-liquid mixture.
We used a technique called chromatography to separate plant pigments. This involves placing a sample of the pigment on a solid medium, such as paper or a column, and allowing a solvent to move through the medium. As the solvent travels, it carries the different pigments at different rates, resulting in their separation based on their different affinities for the solvent and the medium.
One common method to extract chlorophyll from grass is through a process called chromatography. This involves grinding the grass, soaking it in a solvent to extract the pigments, then applying the extract to a chromatography column where different pigments, including chlorophyll, can be separated based on their solubility. Another method could involve using a centrifuge to separate the chlorophyll by spinning the ground grass in a solvent mixture.
The process is called chromatography. It is a technique used to separate and analyze mixtures based on their differential affinities for a stationary phase (the porous paper) and a mobile phase (the solvent).
The two types of paper chromatography are ascending chromatography, where the solvent moves up the paper, and descending chromatography, where the solvent moves down the paper.
The choice between ascending and descending paper chromatography depends on the specific compound being analyzed. In general, descending chromatography is preferred for compounds that are more soluble at the starting point on the paper, while ascending chromatography is better for compounds that are less soluble at the starting point. It is important to consider the properties of the compound and the goal of the chromatography experiment when choosing between ascending or descending.
The stationary phase in paper chromatography is the paper itself.
it can be used in everyday life by liquid chromatography, gas chromatography, thin-layer chromatographyand paper chromatography.
there are different types like gas chrom. and thinlayer chrom Answer: There are two types of chromatography:liquid chromatography gas chromatography
Instead of chromatography paper, you can use materials like coffee filters, filter paper, or even paper towels for paper chromatography tests. These alternative materials can absorb the solvent and help separate the components of a mixture based on their solubility and molecular properties, similar to chromatography paper.
Descending chromatography is faster because gravity aids in pulling the solvent down through the stationary phase, allowing for quicker elution of compounds. In this method, the analytes travel with the solvent flow, resulting in faster separation compared to ascending chromatography where the solvent has to move against gravity.
The paper chromatography technique is based on ascending process in which the loaded amino acid or carbohydrate rises along with the solvent only when the rising fluid is below the point of loading solution, if it is above the loaded solution then descending process occurs

If you like science Paper Chromatography is something to look into. You can take Chemistry classes to find out different ideas on how to use Paper Chromatography.
yes.
Paper chromatography is used as an analytical method not for production.
