Why is it important in the amino acid chromatogram not to touch the paper with your fingers or hand?
The oils in your skin will contaminate them and affect the polarities of the substances affected by capillary action.
The purpose of chromatography is to determine the components of a substance based on polarity. If the medium used to analyze the components is compromised then you will not arrive at a true answer.

How do you get fingerprints?
Fingerprints are obtained by pressing the fingertips onto a special ink pad and then onto a paper card or digitally scanned. The unique pattern of ridges and valleys on the fingers create a distinct fingerprint that can be used for identification purposes.
3 Why do the pigments become separated during the development of the chromatogram?
Pigments become separated during chromatography because each pigment travels at a different rate based on its unique chemical properties like size, solubility, and affinity for the stationary phase. As the solvent moves through the stationary phase, these differences cause the pigments to separate and form distinct bands or spots.
What are the answers for natural selection paper scissors rock?
I am not quite sure what you are talking about, but here is some info for paper scissors rock: Paper beats rock, rock beats scissor and scissor beats paper. If you are scissors and you win, you snap your fingers in the opponents "paper" If you are the paper and you win, you cover your hand over the opponents "rock" If you are the rock and you win, you bang your hands on the opponents "scissors" If you want to be paper, put your hand out. If you want to be rock, make a fist. And if you want to be scissors, hold out your pointer finger and your middle finger. Also, for your next game of paper scissors rock, if you are paper there is a very likely chance you will win. Hope this helps!
How to put biodegradable in a sentence?
Paper is a hundred percent biodegradable. Plastic is not biodegradable. We should use easily biodegradable materials more often, such as paper, wood, cloth, and the like.
How can one effectively write genotypes in a scientific report or research paper?
When writing genotypes in a scientific report or research paper, it is important to use the correct format. This typically involves using uppercase letters to represent dominant alleles and lowercase letters to represent recessive alleles. Additionally, it is important to clearly label the genotypes and provide any necessary context or explanations to ensure clarity for the reader.
What are two ways of identifying amino acids on a chromatogram?
Two ways of identifying amino acids on a chromatogram are by using standards of known amino acid composition to compare retention times and by detecting specific functional groups or side chains using appropriate reagents or detectors.
Why should you not touch chromatogram paper with your hands?
it is because sweat and other substances especially colored ones may be present there. so it is best not to touch chromatogram papers to aviod contaminating it and getting erroneous results..:) chem.student..:)
What is the purpose of spraying the chromatogram with a 0.2 percent ninhydrin solution?
Ninhydrin solution is used and sprayed on the filter paper or any paper used to make the position of the amino acids clearly visible. This is followed by measuring the distance of migration.
Where on the filter paper do you expect the larger molecules to be located in the final chromatogram?
Larger molecules will typically be located closer to the baseline of the chromatogram, as they move more slowly through the stationary phase on the filter paper and do not travel as far as smaller molecules during the chromatography process.
What is paper chromatograph?
Ascending paper chromatography is where a chromatogram rises, or ascends. The paper moves up because the solvent moves it in an upward direction.
What is ascending paper chromatograph?
Ascending paper chromatography is where a chromatogram rises, or ascends. The paper moves up because the solvent moves it in an upward direction.
Why must the chromatogram be removed before the solvent travels the entire length of the paper?
So that you can measure how far it traveled.
What are the names of locating agents in paper choromatografy?
The locating agents commonly used in paper chromatography are ninhydrin, iodine vapor, and UV light. These agents help visualize the separated components on the paper chromatogram.
How can you determine the purity of amino acid using paper chromatography?
To determine the purity of an amino acid using paper chromatography, you would first need to separate the amino acids using paper chromatography. Once the amino acids are separated on the paper, you can calculate the Rf value (retention factor) for each amino acid. Comparing the Rf values of the sample amino acid to a standard of known purity can help determine the purity of the sample.
What determines how far a substance moves on a chromatogram gram?
The substance moves according to the solubility of the substance. For example, dye a's solubility is water is high, it will reach the top of the chromatogram. If the dye is not soluble in water or low solubility in water, it will stop half way on the chromatography paper and/or will separate from the other dyes.
What were the modern computer's predecessors?
Pen and paper, fingers and toes.
Which pigment move slowest in chromatogram?
In a chromatogram, the pigment that moves the slowest is typically chlorophyll b. This is because it has a higher affinity for the stationary phase (usually the paper or the gel) compared to other pigments, leading to less distance traveled. Other pigments, such as carotenoids, generally move faster due to their lower affinity for the stationary phase.
