Abstract
본 발명에 따르면, 원재료의 고체 샘플을 직접 질량 분석할 수 있는 페이퍼 콘 스프레이 이온화(PCSI) 질량 분석법에 사용되는 삼각형의-피라미드-형태로 개량된 페이퍼 콘 팁을 제조하였다. 본 발명에 따른 3차원의 개량된 페이퍼 콘 팁은 샘플 콘테이너, 고체-액체 추출 챔버, 분석물질 이동 채널, 및 전기스프레이 팁(tip)으로 작용하는 효과를 가진다. 따라서, 이러한 페이퍼 콘 팁을 페이퍼 콘 스프레이 이온화 질량 분석법(PCSI MS)에 이용하여 파우더 형태의 정제뿐만 아니라, 가공이나 전처리 되지 않은 푸드 재료를 포함하는 다양한 고체 물질로부터 주요 화학적 핑거프린트를 빠르게 생성할 수 있는 효과를 가진다.
