Chromatography separates chemicals based on their affinity for a stationary phase and a mobile phase, allowing them to travel at different rates. Different types of chromatography like gas chromatography, liquid chromatography, and thin-layer chromatography utilize different mechanisms such as adsorption, partition, ion exchange, and size exclusion to separate the components in a mixture. By adjusting the conditions like solvent polarity, temperature, and column material, chromatography can effectively separate complex mixtures into individual components.
Chromatography separates a mixture of pigments, usually in inks. You can separate colours in food and felt tips. The different solubilities of the different ink pigments, make some rise above others so you can see them clearly.
Paper chromatography is a laboratory technique used to separate and analyze mixtures of substances. It involves applying a sample to a strip of paper, which is then placed in a solvent and allowed to separate into its individual components based on their different affinities to the paper and the solvent. The separated components can be visualized as distinct bands on the paper strip.

This looks to me like a confusion with "chromatography". Say you put some liquid substance on a piece of paper. Some molecules will move (diffuse) faster than others; thus, the substance becomes separated.
Some other methods of separating mixtures include filtration, distillation, chromatography, and crystallization. These techniques work by utilizing differences in properties such as size, boiling point, solubility, or affinity for a solid surface to separate the components of a mixture.
Filtration, evaporation, chromatography, and distillation are some physical processes to separate a mixture.
because it will separate the chemicals and give the investigators some evidence
Some common methods to separate a mixture include filtration, distillation, chromatography, and evaporation. Filtration is used to separate solids from liquids, while distillation can separate liquids based on their boiling points. Chromatography is effective for separating different components in a mixture based on their interactions with a stationary phase, and evaporation can be used to separate a solvent from a solute.
Chromatography is a laboratory process that occurs in several steps and is used to separate mixtures of various chemicals into their individual components. The governing principle of chromatography is that different chemicals in a mixture have different degrees of dissolving in a liquid or sticking to a solid surface. In other words, chromatography can identify a chemical and separate it from a dense mixture of other chemicals and show it on a surface. Various chemicals in a mixture have different sticking ability on a surface. By varying this process in many ways, the chromatography technique can be used to separate any amount of quantities ranging from micrograms (in laboratories) to tons (in chemical plants). There are various chromatography procedures that have become popular since the invention of chromatography by Russian botanist, Mikhail Semyonovich Tsvet, in 1901. In the chromatography processes, a stream of liquid, that is called mobile phase, is made to flow through a tube known as column, and it is packed with porous solid material, called the stationary phase. The sample of the mixture that is to be analyzed is sent through the mobile phase and as the mixture proceeds in the tube, the compounds are separated. Chromatography is preferred over many other techniques as it doesn't cause any molecular changes in the composition of the chemicals involved. Uses of Chromatography Chromatography has evolved to be one of the most widely used chemical techniques to separate particles and contaminates in chemical plants. For example, in the chemical industries, pesticides and insecticides like DDT in the groundwater and PCBs (Polychlorinated biphenyls) are removed by the process of chromatography. As a major testing tool, chromatography is used by government agencies to separate toxic materials from the drinking water and also to monitor air quality. Chromatography is used by pharmaceutical companies to prepare large amounts of pure materials that are further required in making medicines. Also, it is used to check the presence of any contamination in the manufactured compounds. In the field of organic chemistry and pharmacy, chiral compounds are very close to each other in terms of atomic or molecular weight, element composition, and the physical properties. However, they exist in two different forms, called the enantiomers and optical isomers. Both these compounds though may appear to be same, have very different chemical properties. So, in pharmacy, chromatography becomes crucial to analyze the exact chiral compound so that correct medicines can be manufactured. For instance, a compound called thalidomide has two optical isomers and one of the isomers can cause birth defect if a pregnant women consumes it in early stages of pregnancy. So, it is important to carefully separate the isomers. Chromatography is used as a technique to separate the additives, vitamins, preservatives, proteins and amino acids. Some other uses are in the detection of drugs or medications in the urine and the separation of traces of chemicals in the case of fire in houses or buildings. It is also very popular in forensic science for investigative purposes. Chromatography technology has gained immense industrial popularity in the past few decades as it can separate chemicals that just differ even in their atomic orientations in space.
It really depends what the mixture consists of. You would not use the same method to separate sand from gravel as you would to separate salt water from pure water.Some common separation methods include:Filtration: works best for solids suspended in a liquid (to separate sandy water into dry sand and pure water for example) or for two solids with very different particle sizes (to separate a mixture of sand and gravel).Distillation: works to separate liquids that have different boiling points. This method is used to separate alcohol from water (to make hard liquor) and the essentially the same method is used to take oil from the ground and turn it into petroleum products such as gasoline. Chromatography: used to separate mixtures of liquids based on polarity. Many different types exist, including thin layer chromatography (TLC), gas chromatography (GC), and column chromatography. Extraction:used to separate a mixture of solids based on their solubilities in organic and inorganic phases. Differences in pH can also be used to separate different solids by selectively ionizing one compound, causing it to dissolve more readily in inorganic solution.See the Related Questions to the left for more information.

Pudding is chemically complex; basically I would consider it to be a mixture, however, there are some chemicals which are dissolved in other chemicals in the mixture.
A centrifuge might separate out a mixture if the particles that are mixed together are of significantly different sizes/densities, but other than that there aren't any good ways to mechanically separate out a mixture. The answer is filtration because filtrarion seperates the two things after filtrated.... (eg: water and bacteria are a mixture, but if you filtrate them, the 2 substances separate making them unmixtured.) ..... the answer again is filtrate.
