How can one effectively interpret a chromatogram?

To effectively interpret a chromatogram, one must analyze the peaks, retention times, and peak shapes to identify and quantify the compounds present in the sample. Peaks represent different compounds, retention times indicate the time it takes for a compound to travel through the column, and peak shapes can provide information on compound purity. By comparing these factors to known standards or databases, one can determine the identity and concentration of the compounds in the sample.
