A pulsed valve positioned just outside the ion trap electrodes (within the vacuum chamber) has been characterized. The observed gas pulse widths and the maximum ion intensities were found to decrease as the distance between the pulsed valve and the ion trap electrodes increased. An explanation is presented within. The pulsed valve was found to impart temporal separation in ion-molecule reactions by permitting the removal of interfering neutrals. Other factors that affect the degree of temporal separation also are presented.
一个位于离子阱电极（在真空室内）外部的脉冲阀已经过了特性描述。观察到的气体脉冲宽度和最大离子强度随着脉冲阀和离子阱电极之间的距离增加而减小。在本文中给出了一个解释。脉冲阀通过允许去除干扰中性粒子，从而在离子-分子反应中引入时间分离。还提出了其他影响时间分离程度的因素。
