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.
By adding a specific reagent.
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.

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.
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.
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.
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.
To overlap two photos, you can use photo editing software like Photoshop or GIMP. Simply open both photos in the software, place one image on top of the other, adjust the size and position to create the desired overlap effect, and then save the final image.

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.
During destructive interference, the peaks of one wave overlap with the troughs of another wave. This causes the waves to cancel each other out, resulting in a reduction or elimination of the overall amplitude of the wave.

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..:)
