Abstract
Various techniques are provided to determine the presence of trace chemicals corresponding to various materials of interest. In one example, a method includes receiving a vapor-phase nitric acid precursor. The vapor-phase nitric acid precursor is subsequently hydrolyzed in the presence of an acid catalyst to form nitric acid. The nitric acid is then received at a chemical reporter of a chemical detector. A response of the chemical reporter to the nitric acid is detected by the chemical reporter to determine whether materials of interest are present. Additional methods and related devices are also provided.
