    Abstract: This study describes an improved gaseous nitrous acid (HONO) generation system. The mixed solution of sodium nitrite and sulfuric acid was stored in a brown bottle in an ice bath, and the solution was transferred into a glass spiral tube by a peristaltic pump and transferred out from the rear end. The carrier gas (high-purity nitrogen) was used to drive the solution from the spiral tube to stabilize. Gaseous HONO with a high purity (nitrogen oxide NOx interference< 2%) will continue to be generated from the solution with a coefficient of CV< 1%. The reproducibility of the system was good. The experimental results showed that the concentration of HONO was positively correlated with the concentration of nitrite ion (NO2-) and the solution flow rate. Therefore, adjusting the rotational speed of the peristaltic pump could quickly change the concentration of HONO. The technology is simple in structure and easy to operate, making it ideal for laboratory analysis and HONO calibration.
