Say the Gnome you are measuring is made from plastic and you check the density of plastic you will find that it's about 1.2 gm/cm^3. Then you make a Gnome with a weight of 1.2 gm. Suppose you measure that in air at sea level and then in another location at an altitude of about 5000 ft and you see a difference in weight. If you take the density of air at sea level it will be about 0.001225 gm/cm^3 and at 5000 ft it will be about 0.001007 gm/cm^3. You don't really care too much about the air density at a specific location but the difference between the two locations you are doing the measurements since you are interested in the difference in weights, not the absolute values. When you subtract the two typical air densities you find that it's about 0.000218 gm/cm^3. Your Gnome has a density of 1.2 gm/cm^3 so the typical difference due to any air buoyancy would be about 0.018%. That's a difference that probably wouldn't be measurable with the scale used in the experiments. So any difference measured would mostly be due to gravitation or some other unknown factors. That means that measuring the Gnome in a vacuum chamber would make for more accuracy in absolute weights but the difference in weights (what you are looking for) would be so small (due to air buoyancy) because the differences would be more than 3 digits to the right of the decimal point.
