    • A mass spectrometer is disclosed comprising a quadrupole rod set ion guide or mass filter device (6). A broadband frequency signal (10) having one or more notches (11a, 11b, 11c) is applied to the rods of the quadrupole rod set (6). The notched broadband frequency signal (10) causes undesired ions to be resonantly ejected from the ion guide (6). The notched broadband frequency signal (10) has frequency components missing which correspond with the resonance frequency of ions which are desired to be onwardly transmitted. The ion guide or mass filter device (6) enables a plurality of desired ions having different mass to charge ratios to be simultaneously transmitted by the ion guide or mass filter device (6) whilst other ions are resonantly ejected from the ion guide or mass filter device (6).
    • 公开了一种质谱仪,其包括四极杆离子导向器或质量过滤装置(6)。 具有一个或多个凹口(11a,11b,11c)的宽频率信号(10)被施加到四极杆组(6)的杆上。 有缺口的宽带频率信号(10)使不想要的离子从离子导向器(6)共振地弹出。 缺口宽带频率信号(10)具有与期望向前发射的离子的谐振频率相对应的频率分量。 离子导向器或质量过滤装置(6)使得具有不同质荷比的多个所需离子能够由离子导向器或质量过滤装置(6)同时传输,而其它离子从离子导向器或质量过滤器 装置(6)。
