Ions and organc acids in aerosol samples from Ny-Alesund, Svalbard Island, 2015@en

Ions and organic acids were quantified in 7 aerosol samples collected during the Arctic campaign at Gruvebadet Laboratory in 2015. Aerosol samples were collected in quartz fiber filters. They were spiked with isotopically labelled standard solutions (2 - 3 µg/ml) prior extraction. Ion and organic acid content was measured using IC-MS and HPLC-MS.2015年在格罗夫巴德特实验室（Gruvebadet Laboratory）开展的北极考察中，对采集的7份气溶胶样品内的离子与有机酸进行了定量分析。气溶胶样品采用石英纤维滤膜采集。萃取前，向样品中加入浓度为2~3 μg/ml的同位素标记标准溶液进行加标。采用离子色谱-质谱联用（Ion Chromatography-Mass Spectrometry, IC-MS）与高效液相色谱-质谱联用（High Performance Liquid Chromatography-Mass Spectrometry, HPLC-MS）测定样品中的离子与有机酸含量。
