Do a web search on instrumentation for hazardous material identification used by Hazmat teams. For a starting reference see DHS Guide for the Selection of Chemical Detection Equipment for Emergency First Responders. Using the following chemicals:
hydrochloric acid, anhydrous nitric acid (>70%)
It is common practice it takes more than one type of detection equipment to identify a chemical.
Summarize in a page (1 page per chemical) the kind of instrumentation needed to detect that chemical, (choose at least 2 types of detection equipment). Be explicit in your reasoning for choosing the equipment. In summary Pick 2 chemicals/Pick 2 different instruments to detect the chemical, explain your reasoning.
