We have chromatograms!!!!
Figure 1. The chromatograms (or signals) from LACE on two different
channels of ambient air with about 270 ppt of CFC-11 and 80 ppt of CFC-113 (taken
on May 21, 1996). The actual injection took place 60 seconds earlier. We can
get data on the CFCs every 60 seconds because we wrap around the 120 seconds
chromatogram when the baseline is relatively flat in the first 60 seconds.
