Web19 dec. 2024 · Abstract. Due to the important contribution of nitrous acid (HONO) to OH radicals in the atmosphere, various technologies have been developed to measure HONO. Among them, wet-denuder–ion-chromatography (WD/IC) is a widely used measurement method. Here, we found interferences with HONO measurements by WD/IC based on a … Webchromatographic run and can interfere with fluoride. The retention times of anions may differ when large amounts of acetate are present. Therefore, this method is not … Web1 dec. 2006 · 2.1 Chemicals and Solutions. 2.2 IC–ICP–MS Conditions.
