A portable reagent inlet system for a linear quadrupole ion trap (LQIT) mass spectrometer was designed to diminish the impact of air and water on gas-phase ion-molecule reactions. Compared to the traditional reagent mixing manifolds that has been extensively used for decades, the portable system is much simpler and has fewer junctions and a smaller inner space. These changes reduce the amount of air and water introduced into the mass spectrometer with the reagent. Furthermore, unlike the traditional manifolds, the portable system can be easily attached to or detached from the LQIT mass spectrometer. Finally, the price of the portable system is only 1/10 of that of a traditional manifold as estimated in 2022. Therefore, the portable system has several advantages over the traditional reagent mixing manifolds.
设计了一种用于线性四极杆离子阱(LQIT)质谱仪的便携式试剂入口系统,以减少空气和水对气相离子 - 分子反应的影响。与已广泛使用数十年的传统试剂混合歧管相比,该便携式系统要简单得多,连接点更少,内部空间更小。这些变化减少了随试剂引入质谱仪的空气和水量。此外,与传统歧管不同,该便携式系统可以轻松地与LQIT质谱仪连接或拆卸。最后,据2022年估计,该便携式系统的价格仅为传统歧管的1/10。因此,该便携式系统相对于传统试剂混合歧管具有多个优势。
