Based on 2 compounds, one pure, one unpure, can the contaminate be found from a UV spectrum graph of each?

Answer 1

Yes, the contamination would show up as spikes in unexpected regions of the spectrograph.

Answer 2

yes, the contamination would grow as in your pants in the form of gas, which would be released in society killing all those in its path. this would be a problem because its a little known fact that americans are only allowed 2.5 million metric tons of farts a day before the country is taken over by toxic fart gas.
