In GC-MS, numerous neutral molecules originated from carrier gas pass through quadrupole mass filter without being removed, and thereby they are finally transferred to ion detector. When they enter the detector, they may cause noise in the detecting signal. For this problem, some detector structures have already been proposed to remove these neutral molecules. However, they have complex structures and the room for improvement of ion transmission. In this study, we have developed a novel high sensitivity detector which has a simple structure to achieve high ion transmission and to eliminate neutral molecules simultaneously.
