question? An analyst injects a 2µL sample of unknown into a GC-TCD and observed the following:
Peak # 1 Rt = 2.011 min Response = 41334 units
Following the above injection, the analyst mixes 1mL of unknown with
10 µL of pure toluene, and after injecting 2 µL sample observes the following:
Peak # 1 Rt = 2.010 min Response = 41117 units
Peak # 2 Rt = 3.502 min Response = 25667 units
Following this injection, the analyst mixes 1mL of unknown with
10 µL of pure hexane, and after injecting 2 µL sample observes the following:
Peak # 1 Rt = 2.021 min Response = 48335 units
Based on the above data, determine the identity and concentration (in ppm) of the unknown solution
NOTE: density of toluene = 0.87g/mL, density of hexane = 0.66g/mL
