Techniques used to identify spots on a chromatogram include comparing the retention factor (Rf) values of the spots with known standards, visualizing spots using UV light or specific staining reagents, and analyzing the spots through mass spectrometry or infrared spectroscopy. Additionally, methods such as thin-layer chromatography (TLC) often employ mobile phase solvents to separate components, allowing for clearer identification. These techniques help determine the identity and concentration of compounds in the sample.
Locating agent is a substance/liquid that help to separate and analyze colorless substances in chromatography by reacting with the colorless substance to form colored spots on the chromatogram.
To determine if a substance is soluble or insoluble from a chromatogram, observe the distance it travels compared to the solvent front. A substance that moves alongside or close to the solvent front indicates it is soluble in the solvent used, while a substance that remains near the baseline suggests it is insoluble. Additionally, the intensity of the spot can provide clues; more intense spots may indicate higher solubility.
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.
The chromatogram in paper chromatography is just the paper itself. You can look at the paper and see the dots that have risen due to the solvent. The appearance is just simply a piece of paper with dots that have risen from the baseline to a certain spot on the paper. see related link below for more info
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.
As the chromatogram develops, the ink spots begin to separate and spread along the chromatography medium, typically due to differences in the solubility of the ink components in the solvent used. Lighter or more soluble components travel further up the medium, while heavier or less soluble components remain closer to the origin. This separation allows for the identification of the various pigments or dyes present in the ink, as each component will form distinct spots at different positions on the chromatogram.

Flies with spots on their wings have distinct markings that help differentiate them from other fly species. These spots can vary in size, shape, and color, and are often used by scientists and researchers to identify and classify different types of flies.

The base peak in HPLC refers to the peak in the chromatogram that corresponds to the highest intensity or abundance of ions detected by the mass spectrometer. It is used as a reference peak for quantification and identification of other peaks in the chromatogram.
Chromatography is a technique used to separate and analyze mixtures of substances into their individual components. It works by allowing a sample to move through a stationary phase at different rates based on their interactions with the stationary phase. This separation can be visualized by the different bands or spots created on the chromatogram.

A chromatogram is like a chemical fingerprint because a fingerprint is diffrent for every single person in the world and to indicate who is who we use fingerprints, for chromatography its a bit diffrent because you can have more than 2 types of the same thing. For example if someone has been killed & they found a little ink next ti the person, they would collect the ink. Then they would find the few people they think are the suspects. They would take a bit of each suspects' ink and then they would use chromatography to indicate who did it (who has the same ink as the murdurer ). So basically a chromatogram is like a chemical fingerprint because they both indicate who is who or who did what.
Paper chromatography is a technique used to separate and identify components in a mixture, such as ink. A small spot of the unknown ink is placed on a strip of chromatography paper, which is then placed in a solvent. As the solvent travels up the paper, it carries the ink components at different rates, creating distinct spots. By comparing the resulting pattern of spots (the Rf values) with known inks, one can identify the unknown ink based on its unique chromatographic profile.
