Elemental Mercury Passive Samplers

The SKC 520 Series Elemental Mercury Samplers are lightweight personal samplers designed to be worn in the breathing zone of individuals who are potentially exposed to mercury vapour. They are a fully validated, accurate and convenient alternative to active pump sampling.

The samplers use Anasorb® C300 sorbent to collect elemental mercury (Hg) in the vapour phase by positive controlled diffusion. They are analysed by flameless atomic absorption. Validation of the original SKC 520 Series Passive Sampler for Elemental Mercury is reported in OSHA Method ID-140

SKC offers two configurations of the Elemental Mercury Passive Sampler:

A reusable capsule holder deployed with a replaceable sorbent capsule

- The HgChek, a single-piece disposable sampler, in the same style as our VOC Chek passive badges.

Extensively field tested
- Validation based on OSHA Method ID-140
- Meets requirements of OSHA and MDHS (UK) methods
Low cost per measurement
Lightweight and easy-to-use
- Clips to a worker’s collar or pocket
- No pump needed
Validated for 8-hour work shifts
- Extended sample periods up to 120 hours with reusable holder/capsule model
High accuracy and sensitivity
Unaffected by the presence of other gases, including chlorine
Simple analysis using standard laboratory equipment

Note: For sampling low levels of mercury or if particulate mercury must be determined, use an active sampling method rather than a passive sampler.
