An experimental technique for the direct measurement of N2O5 reactivity on ambient particles
experimental technique direct measurement N2O5 reactivity ambient particles
2010/2/8
An experimental approach for the direct measurement of trace gas reactivity on ambient aerosol particles has been developed. The method utilizes a newly designed entrained aerosol flow reactor coupled...
Chlorine activation by N2O5:simultaneous,in situ detection of ClNO2 and N2O5 by chemical ionization mass spectrometry
Chlorine activation N2O5 simultaneous ClNO2 N2O5 chemical ionization mass spectrometry
2010/2/8
We report a new method for the simultaneous in situ detection of nitryl chloride (ClNO2) and dinitrogen pentoxide (N2O5) using chemical ionization mass spectrometry (CIMS). The technique relies on the...
A cavity ring down/cavity enhanced absorption device for measurement of ambient NO3 and N2O5
cavity ring down cavity enhanced absorption device ambient NO3 N2O5
2010/2/8
An inexpensive, compact instrument for the sensitive measurement of NO3 and N2O5 in ambient air at high time resolution is described. Light from a red-emitting laser diode (≈662 nm) is coupled off-axi...
