We present a feasible instrument for the measurement of NO2, total peroxy nitrates (PNs, RO2NO2), and total alkyl nitrates (ANs, RONO2) in the atmosphere. The instrument samples sequentially from three channels at different temperature settings and then measures spectra using one cavity-enhanced absorption spectrometer. The concentrations are determined by spectral fitting and corrected using the lookup table method conveniently. The instrument will promote the study of PNs and ANs.
