    • Provided is a method for testing earth samples for contamination by organic contaminants, and particularly for aromatic compounds such as those found in diesel fuel and other heavy fuel oils, kerosene, creosote, coal oil, tars and asphalts. A drying step is provided in which a drying agent is contacted with either the earth sample or a liquid extract phase to reduce to possibility of false indications of contamination that could occur when humic material is present in the earth sample. This is particularly a problem when using relatively safe, non-toxic and inexpensive polar solvents such as isopropyl alcohol since the humic material tends to be very soluble in those solvents when water is present. Also provided is an ultraviolet spectroscopic measuring technique for obtaining an indication as to whether a liquid extract phase contains aromatic organic contaminants. In one embodiment, the liquid extract phase is subjected to a narrow and discrete band of radiation including a desired wave length and the ability of the liquid extract phase to absorb that wavelength of ultraviolet radiation is measured to provide an indication of the presence of aromatic organic contaminants.
    • 提供了一种用于测试土壤样品以用于有机污染物污染的方法,特别是对于在柴油和其它重质燃料油,煤油,杂酚油,煤油,焦油和沥青中发现的芳香族化合物。 提供干燥步骤,其中干燥剂与土样或液体萃取相接触,以减少在腐殖质存在于地球样品中时可能发生的污染的错误迹象的可能性。 当使用相对安全,无毒和便宜的极性溶剂如异丙醇时,这是特别的问题,因为当水存在时,腐殖质往往很易溶于这些溶剂。 还提供了一种用于获得关于液体提取相是否含有芳族有机污染物的指示的紫外光谱测量技术。 在一个实施方案中,液体萃取相经受包括所需波长的窄且离散的辐射带,并且测量液体萃取相吸收该波长的紫外线辐射的能力,以提供芳族有机物的存在的指示 污染物

    • A soil sample containment device is provided which allows soil samples to be contained within individual sections of a soil sampler liner. The device includes first and second end caps for covering and sealing the respective ends of the soil sampler liner section. Each end cap has a structure for coupling with the opposite end cap for securing the end caps together. The coupling structure for each end cap includes a hook arm and an eye arm. The hook arm of the first end cap can be coupled with the eye arm of the second end cap to secure the end caps together over the ends of the liner section. A flexible sealing material is provided within each end cap for providing a compression seal between the end caps and the liner section. The liner sections can be formed of different lengths and different materials to accommodate different soil tests.
    • 提供了土壤样品容纳装置,其允许将土壤样品包含在土壤采样器衬管的各个部分内。 该装置包括用于覆盖和密封土壤取样器衬里部分的各个端部的第一和第二端盖。 每个端盖具有用于与相对端盖连接的结构,用于将端盖固定在一起。 每个端盖的联接结构包括钩臂和眼臂。 第一端盖的钩臂可以与第二端盖的眼臂联接,以将端盖固定在衬套部分的端部上。 在每个端盖内提供柔性密封材料,用于在端盖和衬套部分之间提供压缩密封。 衬垫部分可以由不同的长度和不同的材料形成,以适应不同的土壤测试。
