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.
