2. Go online to locate the Gas Chromatograms of the samples in the lesson. Click on Sample 1 to see the gas
chromatogram of that sample. This sample is an unknown sample because investigators have not been able
to identify it yet. Now click on the known chromatogram of Acme Lacquer Thinner. Does the chromatogram of
Sample 1 match the chromatogram of Acme Lacquer Thinner? If it matches, you know that Sample 1 is also
Acme Lacquer Thinner. If it doesn't match, try the other known samples to see if they match.
3. Repeat Step 2 for each of the unknown samples. Record all matches in the table below.
