Abstract
A briefcase contains components capable of sampling air for analysis. For example, air can be introduced into the briefcase through inlet ports and that air can be monitored for components of environmental tobacco smoke. A chemical collection device such as a sorbent tube can collect nicotine, a filter can collect respirable suspended particulate matter, and a chemical detector can monitor carbon monoxide levels. The environmental temperature and barometric pressure of the environment can be monitored also. Data is stored on a microcomputer within the briefcase, and can be transferred to a computer at a later time for data analysis.
