We scientists oftentimes like to make graphs. Usually they only serve to confuse people. While I can't definitively link my sarcasm development with my increasing levels of schooling (R2 value not quite good enough for publishing), there is a trend toward increased cynicism over time. Again, this is only personal data based on one replication of my life.

cynisism international units? how do you measure these? GC-MS?
GC-O, actually...you can SMELL them!
What's GC-O?
you know about thixotropy but not gas chromatography...interesting, Bob...engineer?
I know quite a lot about gc and hplc. I was analyzing flavor molecules via GC and HPLC while you were in high school. Just not familiar with GC-O and never afraid to admit that and learn someting new. So the GC provides the seperation of the compound and the "O" provides the identification? You mention smell so this device is better for gasses? Like for head space analysis?
while I was in high school...?
A GC 'souped up' with olfactometer just splits the effluent off the GC column and half goes to the FID (or whatever detector) and the other part goes to a tube which a person smells and writes down what they smell and the elution time...helps to identify which compounds are odor active and present at high enough conc. to contribute to flavor. Usually done with solvent extracts (since they are more concentrated) but you could do it with headspace (SPME I have done it with, but odors are much more faint).
So, now, who are you?
Thanks for the info. In my estimation, this instrument, the way you describe it, would only be of much value in the hands of a very experienced Flavorist. Someone who has the rare ability to recognize 1,000's of chemicals by odor. So, if you use an ether solvent, do you get a buzz while sniffing?
I'm your SECRET admirer and devoted fan.
Ok this post has gone completely geek. I love it.
