Outdoor Ambient Air

The MerPAS® sampler fitted with the white body diffusive barrier is best used for sampling outdoor ambient air of low to intermediate mercury concentrations (0-50 ng/m3). With the high trapping capacity of the MerPAS® substrate, the sampler may be deployed for intervals from 1 week up to 1 year. With air concentrations of 50 to 1000 ng/m3, the sampler can be deployed for time intervals of less than one week. For general guidelines on the appropriate MerPAS® sampling configuration, see the Estimated Sampling Intervals table in the attached document.
