초록
본 연구에서는 Py-GC/MS(Pyrolysis Gas Chromatography Mass Spectroscopy)를 이용하여 단백질 섬유(Protein fiber)로 이루어진 15종의 모피를 열분해 분석하였다. 열분해에 의해 생성된 성분들은 열분해 경로(pyrolysis pathway)및 기원(origin)에 따라 단 분자 열분해 화합물과 이 분자 열분해 화합물로 분류하여 변수화하였고 주성분분석(Principal component analysis)으로 통계 처리하여 섬유의 개체식별, 동물 종류에 따른 미세분류 가능성을 알아보았다.
Abstract
To find the best method to contribute the species of animal hair using analytical pyrolysis, the thermal decomposition fragments of 15 species of animal hair were analysed by Pyrolysis Gas Chromatography Mass Spectroscopy(Py-GC/MS). Then some fragments which originated from mono amino residues and amino residue pairs were arranged as factors to distribute species of fiber and each individual fiber. Principal component analysis was used to verify this method have applicability.
