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.
