The geogas prospecting can analyze the characteristics of mineralization and content of relational elements of the deposit which makes exchange interaction with geogas field by extracting the Ore-forming elements information in it. And the measurement offers a new idea to discuss genetic mechanism of deposit. Although the theory and practice of geogas prospecting are accepted gradually, the natural interferential factors check the development of it (Guo et al., 2007). And the collection medium is of importance to extract the ore-forming elements information. The collection medium are mainly for solid materials in early geogas prospecting (Gao, 2006)Because of the high elemental content in the background values of this kind of medium and poor uniformity, the problems has been effectively solved by using liquid collector to gather gas instead of the solid (Liu et al., 2003). Liquid capture agent has characteristics as follows: 1 capture agent uniform and low content of element background; 2without Preprocessing and uneasily polluted; 3can be analyzed directly and repeatedly. The capture effect of nitric acid and aqua regia is better in different types of trap effect in the study (Liu et al., 2003). The capture of the nitric a-d solution medium also has a stronger ability to capture for most elements. And trapping force of nitric acid aimed at Au, Cu, Zn and other important ore-forming elements is the best in the same concentration of different types of capture agent. Nitrate which capture effect is relatively good is selected as the research object. Firstly, BV-III level nitrate and Wahaha purified water are made up into different concentrations nitrate and nitric acid solution. Secondly, field sampling, using ICP-MS (10) testing and debugging parameter accuracy timely have been done to study the effects of different concentrations of nitric acid on extraction of metallogenic element information. To enrich and develop applicability of the liquid capture agent in geogas prospecting. Also some preliminary exploration work are done for the qualitative research that different concentrations and different kinds of liquid capture agent are chosen to extract information of different ore-forming elements. So the test no matter in theory or in fact is very meaningful.
