| Abstract: | A method was developed for the determination of cross linker contents in thermal interface material by GC/MS and using hexane soxhlet extraction in the paper. The detection limit was 0.01mg/kg for TEOS at S/N=3. The recoveries ranged from 90% to 110%, while the RSDs of precision experiment varied from 3% to 10%. The proposed methed was simple,accurate and high sensitive. |
