Abstract
Description
図1は、液体クロマトグラフィー質量分析装置の概略構成を示す構成図である。タンパク質試料の多くは、酵素消化により断片化され、ペプチド試料とされた後に、液体クロマトグラフィー装置1によって分離される。液体クロマトグラフィー装置1により分離されたペプチドの成分は、質量分析装置本体2に導入され、イオン源3によりイオン化される。イオン生成部であるイオン源3は、タンパク質,ペプチドの有用な多価イオンを生成し易いという特徴を持つ前述のエレクトロスプレーイオン源ESIを用いている。ESIは、イオン化を行う目的成分に対して、イオン化時にダメージを与えないソフトなイオン化法であり、タンパク質やペプチド成分の分子量に由来する多価イオンを生成し易いという特徴を持つ。そのため、夾雑成分等の低分子成分であると1価イオンで検出される傾向が高いため、ESIを採用することにより、ペプチド成分と夾雑成分とを価数の違いから判断することが可能となる。
