Short summary
A continuous source for the generation of pure HONO mixtures was developed and characterized, which is based on the Henry's law solubility of HONO in acidic aqueous solutions. The source shows a fast time response and an excellent long-term stability and can be easily adjusted to HONO mixing ratios in the range 0.05–500 ppb. A general equation based on Henry's law is developed, whereby the HONO concentration of the source can be absolutely calculated with an accuracy of better than 10 %.
