Unformatted text preview: mixture is .033 minutes. Toluene is definitely present because the retention time difference between it and the mixture is .017 minutes. Finall, P-Xylene is definitely present because the retention time difference between it and the mixture is .016 minutes. The minimum number of possible components in the mixture is most likely 4. There were 5 retention times that showed up on the chromatogram and one of these is probably DI water. The maximum number of different components in the mixture is seemingly infinite and difficult to determine. Many components could have longer retention times and did not show up in the 2 minute chromatogram, yet they would have appeared if the solution were to run through the GC for 5 or even 10 minutes....
