Mercury vapor is collected by a thin ultra high-purity layer of gold.  The gold is digested overnight with a mixture of concentrated acids.  Then, an analysis of elemental mercury is performed by cold vapor atomic fluorescence (CVAF).

Each badge comes with a particle screen to prevent particles containing mercury from entering the sampler during monitoring and causing a high biased result.  The screen must be removed immediately after the monitoring is complete.  Best to use a pair of tweezers.  In addition, we recommend the cap be twisted off during sampling and stored away from dusts.  After sampling, remove remove the filter and snap the caps in place.
