The sampling and analysis of soil gas poses several unique challenges when compared to indoor or ambient air monitoring. For instance, soil gas often has higher moisture content and possibly a broader range of compounds. Because of the confined space, typical sites can be very contaminated. Thus sorbent tubes and the analytical system need to deal with this while providing accurate data at the low detection limits required for the toxic regulated compounds. 爱游戏平台注册登录 , with assistance from CARO Analytical Services, has designed a new thermal desorption tube that successfully accommodates the challenges of soil gas sampling and analysis while outperforming the regulatory criteria a detection limits, accuracy and analyte range.
