  Physical, spectral and chromatographic properties of all 209 individual PCB congeners

  摘要：

  Physical, spectral and chromatographic data for all 209 individual PCB congeners is presented. The individual congeners were synthesized and then isolated and purified. Recent emphasis on the source of the toxicity of commercial PCB formulations has increased the need for a complete set of the PCB congeners. Through the use of two capillary GC columns: 40% octadecyl/ 15% phenyl methyl siloxane and 50% phenyl methyl siloxane, it was possible to separate 201 PCB congeners with only four unresolved pairs. The data compiled in this study for all 209 congeners will aid in the identification of selected individual components of these environmental pollutants. The use of this data also presents the opportunity for the improved quantification of the commercial PCB formulations.

  To provide the following instruments 1 and 2 as a low-molecular-weight substance detection instrument employing immunochromatography capable of detecting conveniently and sensitively detecting a low-molecular weight substance such as an environmental pollutant (e.g., a dioxin), as a target substance contained in a test sample: 1. an instrument, which comprises 1) a test sample application section with which a test sample is brought into contact; 2) a label product reaction section containing a label product containing, as a portion thereof, an antibody capable of binding to a target substance contained in the test sample, the label product being not bound to the reaction section; 3) an unbound label product capturing section containing an element capable of capturing the label product which is not bound to the target substance, the element being bound to the capturing section; and 4) a detection section containing a detection element which, when coming into contact with the target substance bound to the label product, causes a visually observable change, and 2. an instrument wherein a test sample is reacted with a labeled antibody containing, as a portion thereof, an antibody capable of binding to a target substance contained in the test sample, and the resultant reaction product is employed for detecting the target substance contained in the test sample.

  提供以下仪器1和2作为低分子量物质检测仪器，采用免疫层析法能够方便、灵敏地检测低分子量物质，例如环境污染物（例如二恶英），作为试样中所含的目标物质：1.一种仪器，包括1）试样应用部分，用于将试样接触；2）标记产品反应部分，含有能够与试样中所含的目标物质结合的抗体作为其一部分，标记产品未与反应部分结合；3）未结合的标记产品捕获部分，含有能够捕获未结合于目标物质的标记产品的元素，该元素与捕获部分结合；和4）检测部分，含有检测元素，当与结合于标记产品的目标物质接触时，会引起可视的变化；2.一种仪器，其中试样与含有能够与试样中所含的目标物质结合的抗体的标记抗体反应，反应产物用于检测试样中所含的目标物质。
