气液包裹体存在并密闭于各种成因的矿物中,是天然的成矿溶液的样品.气液包裹体体积小(一般在几个微米以下)、组份复杂、含量极微.要分析这么小的包裹体成份,用一般分析方法是困难的,需采用进样量少、灵敏度高的分析测试手段.国内多采用比色法,比浊法、电化学等方法测定包裹体液相成份中的阴离子.我院以前采用的是离子选择电极法测定包裹体液相成份中的氟离子、氯离子;比色法间接测定硫酸根离子.这些方法都不能将氟、氯、硫酸根等离子一次同时分析出来,而且分析流程长、测定灵敏度还满足不了包裹体液相成份中阴离子的分析要求.
Gas-fluid inclusions exist and are confined in a variety of generative minerals, and are samples of natural ore-forming solutions. The volume of gas-liquid inclusions is small (usually below a few microns) and the composition is very complicated with very little content. Small inclusions, the general method of analysis is difficult, the need to use a small amount of injection, high sensitivity analysis and testing methods.More the domestic use of colorimetry, turbidimetry, electrochemical methods such as determination of liquid inclusions in the liquid composition Of the anions used in our hospital is the ion-selective electrode method for the determination of fluid inclusions fluoride ion, chloride ion; colorimetric indirect determination of sulfate ions. These methods are not fluoride, chlorine, sulfate and other ions at once Analysis, and analysis of the process is long, the determination of sensitivity can not meet the analysis of anions in the liquid phase composition requirements.
