內容簡介
《質譜(原著第2版)(英文版)》作為一 部成功的教科書。其全新修訂的第2版在內容上得以充分的擴展 ,以其詳盡和準確的敘述。精美的插圖和照片為讀者津津樂道。?新增串級質譜 法,涵蓋了儀器設備、離子激活方法(CID。ECD,ETD,IRMPD) 及其套用?新增敞開式質譜(DART。DE SI等),新增無機質譜。包含元素形態分析和成像,? 新增了所有章節的學習目標,新增先進儀器介紹,諸如or bitraps、線性離子阱、串級TOFs、FT-ICR。以及各種聯用儀器。JurgenH. Gross對書中的概念、方法和技術做出了深入的闡述。指導學生和專業人員從新手逐步 成長為質譜套用的行家裡手。JurgenH.Gross首先介紹了氣相離子化學原理、 同位素組成和精確質量,然後是各種質量分析器和離子化方法的設計,最後是質譜圖的解析和聯用技術。可以說《質譜(原著第2版) (英文版)》是實用信息和基於豐富文獻的理論知識的完美結合。
