脉冲离子束枪与脉冲抽拔（Wiley/McLaren）型飞行时间分析仪相连。无场离子源很好地适应于液体基质的使用。使用大的初级离子脉冲，并通过使用快速模拟数字技术记录产生的次级离子。离子形成和从源区提取之间的时间延迟改善聚焦并允许从亚稳态分解中观察碎片离子。
A pulsed ion beam gun Is Interfaced to a pulsed drawout (Wiley/McLaren) type tlme-of-fllght analyzer. The field-free Ion source Is well-adapted to the use of a liquid matrix. Large primary Ion pulses are used and the resulting secondary ions are recorded by use of fast analog to digital techniques. Time delays between Ion formation and extraction from the source region Improve focusing and allow observation of fragment ions from metastable decompositions.
