Separation of an unknown two-component mixture by distillation and identification of the components by GC analysis. Part C: Gas chromatography and relative response factors. 1. Record the instrumentation parameters used for the analysis. 2. Analyze the "standard" or "known four-component mixture" by GC 3. Use the micro GC syringe to inject 1.0 µ L of the "standard mixture" into the injection port of the Gas Chromatograph. Rinse the syringe a couple of times with the standard mixture to be analyzed before each injection. 4. Press the start button of the plot recorder immediately after you inject. 5.
