A chromatogram is made by separating the components of a mixture through chromatography, which involves passing the mixture through a stationary phase. As the components travel through the stationary phase at different rates, they separate and form distinct peaks on the chromatogram. These peaks are detected and recorded to create a visual representation of the separated components.
What else can I help you with?
How do you reveal the position of a colorless spot on the chromatogram?
By adding a specific reagent.
What happens when you did not replace the cap of the jar to cover on the beaker while developing the chromatogram?
If you did not replace the cap on the beaker while developing the chromatogram, the solvent in the beaker may evaporate faster, leading to changes in the concentration and separation of the compounds on the chromatogram. This could potentially result in distorted or inaccurate results, making it more difficult to analyze the compounds present in the sample.
How can you tell from a chromatogram how many coloured substance there are in a drink?

How can you tell how many coulered substances in a drink using a chromatogram?
You can tell the number of colored substances in a drink using a chromatogram by observing the distinct peaks or bands produced on the chromatogram. Each peak or band represents a different colored substance present in the drink. By comparing the retention times of the peaks to known standards, you can identify and quantify the colored substances in the drink.
How do you obtain chromatogram?
A chromatogram is obtained by running a sample through a chromatography technique such as gas chromatography (GC) or liquid chromatography (LC). The components of the sample separate based on their unique properties as they move through the stationary phase in the column. Detection methods such as mass spectrometry or ultraviolet-visible spectroscopy are then used to generate a chromatogram showing the peaks corresponding to each component.
What are the key differences between a total ion chromatogram and an extracted ion chromatogram?
A total ion chromatogram shows all ions detected by a mass spectrometer, while an extracted ion chromatogram focuses on specific ions of interest by isolating and displaying only those ions.
Why the beaker covered during the development of chromatogram?
During the development of a chromatogram, it is better to cover it with a beaker to prevent evaporation, which will affect the movement of the solute and solvent system. This will ensure that the chromatogram will develop properly.
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 can go wronge in chromatogram?

How can the clarity of a chromatogram be improved?
The clarity of a chromatogram can be improved by optimizing the chromatographic conditions, such as adjusting the mobile phase composition or flow rate, using a column with better resolution, and ensuring proper sample preparation techniques. Additionally, improving the detector sensitivity and reducing background noise can also enhance the clarity of the chromatogram.
How do you reveal the position of a colorless spot on the chromatogram?
By adding a specific reagent.
How do you obtain a concentrated sample of the ink to run a chromatogram?
Go to alaska
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 happens when you did not replace the cap of the jar to cover on the beaker while developing the chromatogram?
If you did not replace the cap on the beaker while developing the chromatogram, the solvent in the beaker may evaporate faster, leading to changes in the concentration and separation of the compounds on the chromatogram. This could potentially result in distorted or inaccurate results, making it more difficult to analyze the compounds present in the sample.
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.
Would a pure substance show more than one color or spot in a chromatogram. explain?
No, a pure substance would only show a single color or spot in a chromatogram because it consists of only one compound without any impurities. Each compound present in a sample will appear as a distinct spot with a unique color in the chromatogram.
How to read an HPLC chromatogram effectively?
To read an HPLC chromatogram effectively, start by identifying the peaks representing different compounds. Analyze the peak shapes, heights, and retention times to determine the compounds present. Compare the chromatogram to a standard or reference for accurate identification. Pay attention to any abnormalities or unexpected peaks that may indicate issues with the analysis.
