quadrupole ion trap

The MS and MS2 spectra of tetrandrine and sinomenine in positive ion detection mode were analyzed by electrospray ionization quadrupole ion trap mass spectrometry ( ESI-QITMS), and their cleavage patterns were summarized.

用电喷雾离子阱质谱（ESI-QITMS）研究了粉防已碱和青藤碱在正离子检测方式下的一级质谱和二级质谱，总结出各自的ESI碎裂规律。

A new GC detector& quadrupole ion trap detector ( ITD) is described.

本文介绍一种新型气相色谱仪鉴定器&四极离子阱探测器（ITD）。

The principle of ion Trap Detector ( ITD) is different from that of quadrupole and magnetic mass spectrometers.

离子阱检测器的原理不同于四极杆和磁质谱仪。

There are many types of mass spectrograph, such as quadrupole mass spectrograph, ion trap mass spectrograph, time-of-flight mass spectrograph, etc.
