Short summary

The generation of clean calibration gases is critical for accurate ambient air measurements. Here, we describe a source of HONO vapour dynamically generated from reaction of HCl and NaNO₂. The output was characterized by Fourier transform infrared (FTIR) and thermal-dissociation cavity ring-down spectroscopy (TD-CRDS) and was stable, tuneable, and > 95 % pure. We show how generation of unwanted side products (NO, NO₂, and ClNO) can be avoided.
