Abstract

Preparation of standard NO ₃ gas is explored at the level of ppbv for atmospheric measurements utilizing an LIF instrument. The sequence of thermal decomposition of N ₂O ₅ and gas phase titration of NO ₃ by adding NO is useful. To reduce NO ₂ contamination in N ₂O ₅, N ₂O ₅ trapping after mixing NOx and O ₃ was adopted. As a convenient method in the field studies, dynamic mixing of NOx and O ₃ was explored.
