Sampling time is not critical for industrial exposure monitoring. Metals with timing “not critical” have very long elimination half-lives and accumulate in the body over years, some for a lifetime. After a couple of weeks of exposure, specimens can be collected at any time.

Storage Instructions

Maintain specimen at room temperature.

Stability Requirements



Room temperature
