Mass Spectrometer and How to Find Atomic Mass

Mass Spectrometer and How to Find Atomic Mass

Mass Spectrometer and How to Find Atomic Mass. It has several stages of operation that you must get familiar with (i.e. learn!): injection of the sample vaporization of the sample (if it's not already gaseous) ionization of the sample acceleration of the ions deflection of the ions

M ass S pectrometer(MS). 분자가 MS 내로 들어가면 분자는 이온화됨과 동시에 더 작은 이온들 (fragments) 로 쪼개진다 . 쪼개진 이온들은 그들의 질량 / 전 하 (m/z ) 비에 따라 선택적으로 분리되어 이온수에 비례해 signal 을 만든다 . 이온들의 질량 / 전하비는 이온들의 생성된 양 (Abundance) 의 함수로 표시되어 mass spectrum 이 그려지며 , 이 mass spectrum 을 이용하여 미지성분의 정성확인을 할 수 있다 .
