The problem can be stated as follows: A mixture of three solvents, A, B, and C, is provided. The composition of the mixture is unknown but it is suspected that solvent C is present only in small quantities. Using gas chromatography, how can you determine the relative amounts of each solvent in the mixture and confirm the presence of solvent C in the mixture?
