Linear quadrupole ion trap 是线性四极离子阱质谱;LTQ-Orbitrap XL由两种不同类型的质谱构成,前端是二维线性离子阱质谱LTQ,提供多级结构碎片信息;后端是Orbitrap静电场轨道阱质谱,提供高分辨率及高精度的分子量信息;LTQ Orbitrap Velos即轨道阱质谱仪;Thermo Scientific Orbitrap Elite MS是一款业界领先的高性能组合式质谱仪,结合了新型高场OrbitrapTM 分析器和最新双压线性离子阱Thermo Scientific Velos Pro。这几款都是赛默飞的仪器型号来着。
The linear ion trap (LIT) is a type of ion trap mass spectrometer. In a linear ion trap, ions are confined radially by a two-dimensional radio frequency (RF) field, and axially by stopping potentials applied to end electrodes. Linear ion traps have high injection efficiencies and high ion storage capacities.

看英语缩写,可知道个大概。前面是配置构成,最后尾词是自夸特色的词,XL,extra large;Elite,精英;Velos,不知道。一般Q都是指代四极杆吗?二维线性离子阱质谱LTQ里面也有四极杆?
