Cluster measurements at CLOUD using a high resolution ion mobility spectrometer- mass spectrometer combination
Mass spectrometry is powerful tool for environmental and atmospheric chemistry analysis. Modern mass spectrometers demonstrate low detection limits, high sensitivity, and high resolving power. However, such high performance is not always enough to identify ambient ion clusters due to the clusters braking at the atmospheric pressure-to-vacuum interface of mass spectrometer. This study presents a...

متن کاملIon mobility-mass spectrometer interface for collisional activation of mobility separated ions.
An ion mobility-mass spectrometer (IM-MS) interface is described that can be employed to perform collisional activation and/or collision-induced dissociation (CID) with good transmission of mobility separated ions to the MS analyzer. The IM-MS interface consists of a stacked-ring ion guide design, where the field strength and pressure ratio can be operated such that structural rearrangement rea...
متن کاملDesign, Construction and Calibration of a Laser Ionization Time-of-Flight Mass Spectrometer
A time-of-flight mass spectrometer (TOF-MS) developed in our laboratory at Isfahan University of Technology is described here. The TOF-MS instrument uses laser as the ionization source which provides an opportunity to investigate the ions formed in laser ablation or desorption. The TOF-MS has an ionization chamber containing an accelerator and an ion lens to focus the ions into a one meter line...
متن کاملInfluence of the coupling between an atmospheric pressure ion mobility spectrometer and the low pressure ion inlet of a mass spectrometer on the mobility measurement
Ion mobility spectrometers (IMS) are versatile gas analyzers. Due to their small size and robustness, combined with a very high sensitivity, they are often used in gas sensing applications such as environmental monitoring. In order to improve the selectivity, they are typically combined with a mass spectrometer (MS). Since IMS works at atmospheric pressure, and MS works at vacuum, a special int...
