Short summary

An incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS) technique has been developed for the in situ monitoring of NO₃ radicals in the CSA simulation chamber at LISA. The optical cavity allows a high sensitivity for NO₃ detection up to 6 ppt for an integration time of 10 s. The technique is now fully operational and can be used to determine rate constants for fast reactions involving complex volatile organic compounds (with rate constants up to 10⁻¹⁰ cm³ molecule⁻¹ s⁻¹).
