Whatman filter paper is the traditional laboratory filter paper used for chromatograms. It is a good quality paper with reasonably reproducible performance. It is pure, containing few contaminants, that could interfere with the chromatoograms. Many published papers used it making it a kind of default standard.

MaxineFilter paper is used in chromatography because it is porous and allows the solvent to travel through it by capillary action. This helps separate the components of a mixture based on their solubility and affinity for the stationary phase. The filter paper also provides a large surface area for the separation to occur effectively.

What is chromatography paper called?
Chromatography paper is also called filter paper because it is commonly used to separate mixtures of substances based on their different polarities as they move through the paper.
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 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.
How will you separate the components of black ink using chromatography?
You can use the filter paper or chromatography paper to separate the different components in black ink.
What can you use instead of chromatography paper in a paper chromatography test?
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.

What is used as the stationary phase in paper chromatography?
The stationary phase in paper chromatography is the paper itself.

Can paper chromatography be used to separate large amounts of solutions Why or why not?
Paper chromatography is used as an analytical method not for production.
Why did different dyes travel up the filter paper at different rates in paper chromatography?
different dyes travel with different speed/rates on filter paper in paper chromatography as they have nothing to do with the filter paper as it is the stationary medium while the rates depends upon the interaction between the solute i.e., dyes and the mobile phase i.e., the solvent.
A hypothesis for paper chromatography?
A possible hypothesis for paper chromatography could be: Different molecules in the mixture will separate and move at different rates along the paper strip due to variations in their solubility and affinity for the stationary phase.
What is pen chromatography?
Pen chromatography is a simple paper chromatography technique where a capillary pen is used to apply a small sample to filter paper. As the solvent moves up the paper, different components in the sample will separate into distinct bands based on their interactions with the paper and the solvent. This technique is often used for separating and identifying components of a mixture.
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 are the two techniques used in paper chromatography to identify caffeine in tea?
The two techniques used in paper chromatography to identify caffeine in tea are stationary phase and mobile phase. In stationary phase, a sheet of filter paper is used to hold the sample, while in mobile phase, a solvent is used to carry the sample along the paper. These techniques separate the components of the sample based on their affinity for the stationary and mobile phases.
