STEL监控 - 真空取样瓶

STEL Monitoring - Vacuum Sampling Bottles

短期暴露限制（STEL）监测可以使用真空瓶式Vac采样器和MiniCans进行，也可以使用第82-85页上的新型氦气吸收式采样（HDS）个人监测器进行监测。

Vacuum sampling for 15 minutes into a Bottle-Vac or MiniCan is easily accomplished using a simple restrictor and transfer line leading to the evacuated sampler worn on a convenient waist-mounted pouch. The chart below shows the fill times based on the size of the sampler used. Note that lling with a critical orice sampler maintains a constant flow rate only until the canister or Bottle-Vac is half full, then the flow rate will begin to decrease. Fortunately, the sampling can be stopped at 50% of atmospheric pressure while still providing several times the amount of sample needed by a laboratory to perform the analysis. Typically laboratories will measure the pressure, dilute the sample 2-3x to create a positive pressure in the container, and then adjust for the dilution when determining concentrations. Using this approach, the dilution amount is very reliably determined via pressure measurement, allowing a high degree of accuracy.
