Description
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, potentially 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.
