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 technique can be used to separate a mixture in science?
One technique that can be used to separate a mixture is chromatography. In chromatography, the components of the mixture are separated based on their different affinities for a stationary phase and a mobile phase, allowing them to move at different rates and be identified.
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 is chromatography in science?
chromatography seperates substances from an object
Where may one learn about paper chromatography?
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.
How do you use chromatography in everyday life eg forensic science and Csi crime scene Inveatigation?
Chromatography is used in forensic science to separate and analyze complex mixtures of compounds found in samples such as blood, drugs, or fibers collected from crime scenes. In CSI investigations, chromatography helps identify unknown substances, compare samples, and provide evidence for solving crimes, through techniques like gas chromatography and high-performance liquid chromatography.
Who discovered candy chromatography?
Candy chromatography was not discovered by one specific individual. It is a scientific technique that involves separating and identifying different components in candy dyes through a process similar to traditional chromatography.
What does chromatography mean in Greek?
The name Chromatography comes from the greek word "Chromos" meaning color and "grafein" meaning to write. So, Chromatography is "writing with colors"...
Pictures of science apparatus used in school labs I need pictures of science apparatus used in school labs?
To get all of kinds science equipment/apparatus go to Wikipedia.com and look up pH meter, high performance liquid chromatography (HPLC), gas chromatography mass spectroscopy (GC/MS), pipettes, vortex, electrophoresis, and a desiccator. This should get you started.
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 technique can be used to separate a mixture in science?

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.
How can ink chromatography be used in forensic science?
Ink chromatography can be used in forensic science to analyze pen inks and determine if two or more inks are chemically similar, aiding in forgery detection. By separating the ink components, analysts can compare the ink profiles from different sources to provide evidence in cases involving counterfeiting or document fraud.
What does pure mean scientifically?
In science, purity refers to the extent to which a substance is free from impurities or contaminants. A pure substance consists of only one type of molecule, atom, or ion. Purity is often determined through techniques such as chromatography or spectroscopy.
