- Sampling time is end of shift for industrial exposure monitoring. Analytes with timing end of shift (meaning the last two hours of exposure) are eliminated rapidly with a half-life less than five hours. Such compounds do not accumulate in the body and, therefore, their timing is critical only in relation to the exposure period.
