SKC 520-02A Inorganic Mercury Passive Sampler - Manual

Passive Sampler for Inorganic Mercury
Catalog No. 520 Series
Introduction
The 520 Series Passive Sampler for Inorganic Mercury is a lightweight, reusable
personal sampler designed to be worn in the breathing zone of individuals who
are potentially exposed to inorganic mercury vapor.
The sampler is comprised of a reusable housing and a replaceable sorbent cap-
sule. The sample enters the sampler by positive controlled diff usion. The sorbent
is analyzed by fl ameless atomic absorption. The sampler housing can be cleaned
and reused with a new sorbent capsule. Validation of the SKC 520 Series Passive
Sampler for Inorganic Mercury is based on OSHA ID-140.
