Chromatography is a technique used to separate and analyze mixtures of substances. It works by passing a mixture through a stationary phase, which interacts differently with each component of the mixture. This causes the components to move at different speeds, leading to their separation. Chromatography is used in various fields such as chemistry, Biology, and forensics to identify and quantify substances in a mixture.

What are the key differences between anion exchange chromatography and cation exchange chromatography?
Anion exchange chromatography and cation exchange chromatography are both types of ion exchange chromatography used to separate molecules based on their charge. The key difference between them is the type of ions they attract and retain. Anion exchange chromatography attracts and retains negatively charged ions (anions), while cation exchange chromatography attracts and retains positively charged ions (cations).
What are the key differences between paper chromatography and thin layer chromatography?
Paper chromatography and thin layer chromatography are both techniques used to separate and analyze mixtures of substances. The key differences between them lie in the materials used and the method of separation. In paper chromatography, a strip of paper is used as the stationary phase, while in thin layer chromatography, a thin layer of silica gel or other material is used. Additionally, in paper chromatography, the solvent moves up the paper through capillary action, while in thin layer chromatography, the solvent is applied directly to the stationary phase. Overall, thin layer chromatography is faster and more efficient than paper chromatography, but both techniques have their own advantages and applications in analytical chemistry.
What is used as the stationary phase in paper chromatography?
The stationary phase in paper chromatography is the paper itself.
What are the two types of paper chromatogaphy?
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.
What are the key differences between normal phase chromatography and reverse phase chromatography?
Normal phase chromatography and reverse phase chromatography are two types of chromatographic techniques that differ in the polarity of the stationary and mobile phases. In normal phase chromatography, the stationary phase is polar and the mobile phase is nonpolar, while in reverse phase chromatography, the stationary phase is nonpolar and the mobile phase is polar. This difference in polarity affects the retention and separation of compounds in the sample.
How does a liquid liquid chromatography work?
The principle is found in "Counter Current Extraction"
What are the different types of chromatography?
there are different types like gas chrom. and thinlayer chrom Answer: There are two types of chromatography:liquid chromatography gas chromatography
What are 3 types of chromatography?
1. thin -layer chromatography 2. gas chromatography 3. liquid chromatography
What are the advantages for gas chromatography?
its completely and utterly rubbish and doesn't work it is only for the movies
How many types of Chromatography are there?
Types of Chromatography:Gas ChromatographyLiquid ChromatographyIon Exchange ChromatographyAffinity Chromatography
How is paper chromatography used in everyday life?
it can be used in everyday life by liquid chromatography, gas chromatography, thin-layer chromatographyand paper chromatography.
What is chromatography in science?
chromatography seperates substances from an object
Which dyes adhere best to chromatography paper?
Dyes that are more polar tend to adhere better to chromatography paper because they interact more strongly with the cellulose fibers in the paper. Therefore, water-soluble dyes like food coloring or ink tend to work well for paper chromatography.
What is grass chromatography?
Grass chromatography is a method used to separate and analyze the components of grass samples. It involves using a chromatography technique, such as thin-layer chromatography or gas chromatography, to separate the different compounds present in grass based on their chemical properties. Grass chromatography can be used to identify and quantify specific compounds like chlorophylls, carotenoids, and other pigments present in grass samples.
Is planar chromatography same as gas chromatography?
No, they are different techniques.
When was Journal of Chromatography A created?
Journal of Chromatography A was created in 1958.
When was Biomedical Chromatography created?
Biomedical Chromatography was created in 1986.
