Commercial passive monitoring devices for volatile organic chemicals were evaluated to determine their potential application to ambient air concentrations (0.1 to 50 ppbv). A high-performance passive device was developed for short-term, low-level monitoring applications. The stainless steel monitor is small, simply designed, and inexpensive. It has a high equivalent sampling rate, is reusable and rechargeable, and is amendable to thermal desorption. Laboratory and field tests with Tenax GC as the sorbent have shown that the monitor compares very favorably with active (pump-based) samplers.
