【摘要】 以新疆天山乌鲁木齐河源1号冰川上采集的大气气溶胶样品为例,就滤膜选取、样品采集、提取方法、分析技术、污染防范等方面进行了介绍,给出了离子色谱法分析中的检测限和不确定值。这种方法和技术同样适用于测定其它偏远高山地区和极地地区大气气溶胶中的可溶性成分。更多还原

【Abstract】 Aerosol samples were taken from Glacier No.1, at Urumqi river head, Tianshan Mountains, Xinjiang, Northwest China, as an example. Sampling and extracting methods, analyzing techniques, measures of avoiding contamination were introduced. Meanwhile, the detection limits and the uncertainty for atmospheric ion concentartions were presented. These limits made the techniques suitable in very remote atmospheres, such as other high mountains and pole sites.更多还原
