HS-SPME GC/MS를 이용한 젤펜잉크의 휘발성 성분

Abstract

젤펜잉크 중 휘발성 성분을 스크리닝하여 개체특성자료를 확보하고자 3개국에서 생산된 16종의 흑색 젤펜잉크 카트리지를 시료로 분석하였다. 검출된 성분은 총 20종으로 isopropylalcohol, 2-methyl-2-propanol, 2-butanone, hydrazinecarbothioamide, benzeneacetic acid (ethyl ester), benzeneacetic acid, dimethoxymethy-silane, 2,2-dimethoxybutane, tetrahydro-2-methyl-furan, 1,2-ethanediol, silicic acid (tetramethyl ester), 1,2-propanediol, propyleneglycol, 3-ethyl-3-hexanol, 1,1-dipropoxy-propane, 2-butoxy-ethanol, 2,2'-oxybisethanol, 1-butyl-benzene, 2-pyrrolidinone, 2-(2-butoxyethoxy)-ethanol이었다. 그중 2,2-dimethoxybutane은 3.02~47%의 비율범위로 16종 젤펜 모든 시료에서 검출되었으며 tetrahydro-2-methyl-furan의 경우 1.19~52.19%로 GP1을 제외한 15종의 시료에서 검출되었다. 특히 일본산 제품 5종에서는 1,2-ethanediol가 52.83~95.84%의 범위, 한국산 동아제품 3종에서는 76.17~93.51%의 범위로 1,2-propanediol가 높은 함유율로 나타나 생산국에 따른 특성과 제조사별 특정성분의 함유분포를 알 수 있어서 잉크 휘발성 성분으로 개체특성을 확인하였다. In this study, VOCs of black gel pen inks was screening to identify individual characteristic of gel pen inks. Detected VOCs was total 20 species(isopropylalcohol, 2-methyl-2-propanol, 2-butanone, hydrazinecarbothioamide, benzeneacetic acid (ethyl ester), benzeneacetic acid, dimethoxymethy-silane, 2,2-dimethoxybutane, tetrahydro-2-methyl-furan, 1,2-ethanediol, silicic acid (tetramethyl ester), 1,2-propanediol, propyleneglycol, 3-ethyl-3-hexanol, 1,1-dipropoxy-propane, 2-butoxy-ethanol, 2,2'-oxybisethanol, 1-butyl-benzene, 2-pyrrolidinone, 2-(2-butoxyethoxy)-ethanol). We detected 2,2-dimethoxybutane (3.02~47% ratio) and tetrahydro-2-methyl-furan (1.19~52.19% ratio), 1,2-ethanediol (52.83~95.84% ratio). In case of manufacturer, manufactured ink was able to discriminate between Japan and Korea by distinct characteristics (Japan: 1,2-ethanediol, 52.83~95.84%, Korea: 1,2-propanediol, 76.17~93.51%). The results of this study indicated that distinct characteristic about manufacturers and brands could make a classifring tool of inks for identification of between gel pen inks.
