摘　　要：通过对不同介质地气的空白、样品的各种对比分析,基本上可以肯定:含有一定浓度的高纯的液体捕集介质在一定程度上对地气样品的捕集是有效的,并具有元素含量本底低、易操作、分析过程简单等优点;不同介质对地气中不同元素的捕获能力有差异,王水对Au、Ag、Cu、Zn等元素的捕获能力要强于硝酸,泡塑对金元素的吸附也有一定的优势。因此,在今后的实际工作中,可根据具体矿床类型,选择合适的介质或2种介质配合使用。Through comparison of geogas's blank and sample for different mediums, it is concluded that highly purified liquid capture medium with certain concentration is effective for collection of geogas's samples, which has the advantages of low background, easy operation, and simple analytical procedure. Different mediums have different capture capabilities for different elements. For example, the capture capability of aqua regia is stronger than that of nitric acid for Au, Ag, Cu, Zn. Poly-plastic has some advantage to adhere Au. Therefore, suitable medium and or conjugating use of two mediums should be considered on the basis of type of concerned mineral deposits henceforth.
