It is very cool the way you explained how you found th CFC's but I don't understand how you track them because that part was not explained.

CFC's are detected in the air using a gaschromatograph (see journal CFC's). The gas-chromatograph takes in air from the outside . It can separate different gases of the air and makes them appear on a graph as a peak. That is how we know how much CFC is in the air. E Bergholz
