| Popis: | International audience; Contamination modeling has struggled with the challenge of species separation. Without the capabiliity to physically identify the chemical nature of contaminants and their contributions, the realistic correspondence between a chosen model and its underlying physics is very difficult to demonstrate. With the development of TGA/MS coupling experimental techniques and specific data treatments, a species separation was achieved on the ScotchWeld EC2216 adhesive. After a detailed exposure of the species separation need, this paper presents the experimental facility and the numerical procedure to effectively get contaminants identification and differentiate their contribution in a mixture. |
