Flow diagram of the surface chemistry reactant air delivery and experiment system (SCRADES).
Log plots of ring-down traces for τ empty (no NO3 •) and (124 ppt NO3 •) with linear fit.
Drift of τ empty over a 72 h period with mean ring-down time (140.3 μs) bracketed by standard deviation (±1.6).
Percent loss of NO3 • between the CRDS cavity and the experiment chamber based on N2 flow through the N2O5 trap. Error bars represent the standard deviations from five separate experiments at each flow rate.
Calculated ideal NO3 • concentration to be measured by CRDS based on N2 flow through N2O5 trap (green). Actual NO3 • concentration measured by CRDS (red). Calculated NO3 • concentration in experiment chamber (blue).
Results of CRDS τ empty (no NO3 •) drift experiments.
