This article describes a portable reagent inlet system for a linear quadrupole ion trap mass spectrometer, designed to reduce the impact of air and water on gas-phase ion-molecule reactions. Compared to traditional reagent mixing manifolds, the portable system is simpler, has fewer junctions, a smaller inner space, and can be easily attached or detached from the mass spectrometer.
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.
