Combined amino acids in aerosol samples from Ny-Alesund, Svalbard Island, 2015

Combined amino acids (CAA) were quantified in 7 aerosol samples collected during the Arctic campaign at Gruvebadet Laboratory in 2015. Combined amino acids (CAA) refer to amino acids contained in peptides, polipeptides and proteins. Aerosol samples were collected in quartz fiber filters. They were spiked with isotopically labelled standard solutions (2 - 3 µg/ml) prior extraction. CAA content was measured using HPLC-MS.
