ABSTRACT:
A novel multi-gas passive sampler is described, whereby different collection media are packed into one passive sampler to collect a variety of air pollutants (or groups of air pollutants) at the same time. By comparison with known commercially available passive samplers—in which only a single collection medium is used to collect a single air pollutant of or group of air pollutants—the MGPS is more cost effective, convenient to use and more environment-friendly.
