摘要：
一种离子迁移谱仪或其它分析仪器具有用以使样品气体或蒸气产生电离的电晕放电针(20)。门(3)被打开或关闭从而允许和防止通过电晕放电所产生的离子进入漂移室(4)中。对电晕放电针(20)和门(3)的工作进行控制，从而使得所述门在至少两次放电过程中被打开，从而允许通过最近放电所产生的更快的离子连同通过较早放电所产生的较慢的离子一起通过。
摘要（英）：

An IMS or other analytical instrument has a corona discharge needle (20) to ionize sample gases or vapours. A gate (3) is opened or closed to admit or prevent entry of the ions produced by the corona discharge to a drift chamber (4). The operation of the corona discharge needle (20) and the gate (3) are controlled such that the gate is open during at least two discharges, to admit faster ions produced by the most recent discharge together with slower ions produced by an earlier discharge.
