What are some possible alternatives for paper chromatography?
Some possible alternatives for paper chromatography include thin-layer chromatography (TLC), gas chromatography, high-performance liquid chromatography (HPLC), and capillary electrophoresis. These techniques offer different separation mechanisms and have varying applications depending on the analyte and desired outcome.
What is paper chromatography?
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.
How is tie dye chromatography?
Tie dye chromatography is a technique that separates mixtures of colored components through capillary action. When a sample is applied to a chromatography paper and allowed to run in a solvent, the different colors separate based on their solubility and interaction with the paper. This process creates distinct bands of color, similar to the patterns seen in tie dye clothing.
Uses for paper chromatography?
They are used in many scientific studies to identify unknown organic and inorganic compounds. They are also used in crime scene investigation, DNA and RNA sequencing, among others. Essentially, any solution can be separated through some form of chromatography.
Disadvantages of paper chromatography?
The only disadvantage, like any paper chromatography method, is that the test take a lot of time - typically 45 to 90 minutes.This method also yield little amount of pigments when it comes to the extraction of the isolated pigments. Several tests must be run to gather a respectable amount for further chemical tests.

In chromatography why do some colours not spread up the paper?
Some colors may not spread up the paper in chromatography because they may have a higher affinity for the stationary phase (paper) than the mobile phase (solvent). This means they are more likely to stick to the paper and not move as far as other colors.

Why some substances in chromatography will travel futher up the paper?
Substances travel further up the paper in chromatography due to differences in their affinity to the mobile phase (solvent) and the stationary phase (paper). Substances that have higher affinity for the solvent will move faster and farther up the paper, while those with higher affinity for the stationary phase will travel slower and remain closer to the origin.
Why will some substances travel further up the paper?
Some substances will travel further up the paper in chromatography because they are more attracted to the mobile phase (solvent) and less attracted to the stationary phase (paper). This results in them moving faster and traveling a greater distance up the paper.

Why stop paper chromatography from reaching the top of the paper?
The end of the paper nearest the spot is allowed to be in contact with a suitable solvent, WITHOUT immersing the spot itself. If the spots were immersed they would dissolve in the solvent and be pulled down into the solvent itself.
Disadvantages of using paper chromatography?
TLC has following advantages over paper chromatography: greater speed greater sensitivity for many substances than paper Small sample requirement Usually sharper preparation Different kind of reagents can be applied without damaging the plate
How can substances be separated?
Substances can be separated through various methods such as filtration, distillation, evaporation, chromatography, and centrifugation. These techniques take advantage of the different physical and chemical properties of the substances to isolate them from each other.
How do you separate blue dye and red dye?
Chromatography-This is when you put dye on a piece of special paper and put it in some water. When the water is soak up the dye will separate.
