As the majority of what enters through the sample cone (and consequently into the vacuum regions) is Argon and not Matrix the amount of matrix Pumped awaywill be miniscule, if you are pumping away matrix will you not also pump awaythe analytes?

你接触过那么多家的仪器，分子泵不是把气体抽出去的，而是撞出去的，离子在电场作用下，被加速，聚焦，只有不受电场作用的粒子扩散到分子泵入口，被抽走。
