In recent years there has been much concern about air pollutants in the
museum environment. GCI has undertaken an extensive Environmental
Research Program quantifying pollutants in the museum environment.
Dynamic sampling methods were used to detect low parts per billion (ppb)
levels of many of these pollutants. Simple, economical passive monitors
have been developed based upon the chemistry used in the dynamic
sampling modes. Commercially available monitors and a generic passive
sampler are discussed. Some passive samplers can be used for direct reading
(no analysis required) determination of a number of pollutants. Validation
studies are presented along with applications and use of the passive monitors.
