used here purely for demonstration purposes. Indeed, there is good reason to suppose that most thermally stable reactive species can be generated in this manner. In a sense, the present results remove the "hardware" aspects from consideration in reactive gas generation and focus attention on the thermal properties of organic molecules. We also note that the majority of substances that are presently considered hazardous are, in fact, liquid or solids at ambient conditions and are not particularly unstable in the bulk. For such substances, generation can be effected without the pyrolyzer and obviously our observations with respect to reproducibility, precision, accuracy, and range will hold with equal, if not greater, force. Thus, this instrument may well provide a simple general solution to a difficult analytical problem.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
